The
transition of the two-seater Commonwealth Aircraft Corporation CA-6 Wackett
Trainer into the all-metal single seat agricultural Yeoman YA-1 Cropmaster
250 series is outlined in these topics in this series:

CA-6 WACKETT TRAINER
-
YEOMAN YA-1 CROPMASTER

This
paper details the steps and lists the Wackett Trainers modified along
the way.
By 1956 Kingsford
Smith Aviation Service Pty Ltd at Bankstown Airport, Sydney still held
a considerable number of RAAF disposals CA-6 Wackett Trainers in storage
in hangars at Bankstown Airport, Sydney. Company founder John T. Brown
OBE had purchased 91 Wacketts from RAAF disposals and established KSAS
in 1946. His son, wartime pilot Peter Brown DFC, who was also a foundation
director of KSAS, along with KSAS engineer C.W. (Bill) Smith were convinced
the CA-6 could be modified for agricultural use, and saw this is as an
effective way to utilise their stored Wacketts.
KSAS had
considerable experience in modification and re-engining of various aircraft
types. The company had carried out agricultural modifications to Austers
and built the KSAS PL-7 Tanker designed by Luigi Pellarini.
In
1957 Bill Smith designed an arrangement for a stock CA-6 Wackett Trainer
to have a hopper installed in the front cockpit area with the pilot sitting
in a slightly raised position in the rear seat position. The original
windscreen and overturn pylon were moved rearward. It retained the Warner
Scarab radial engine and little modification of the basic airframe was
involved, except some mods to reduce empty weight. It had a good performance
for minimum cost and there was obvious potential for the growing Australian
aerial agricultural market. KSAS development work, experimenting with
position of pilot and hopper, resulted in the KS.1,
KS.2 and KS.3 Wackett-Cropmaster. Five of these aircraft had been
completed (VH-AJH, VH-FBD (1, FBD (2, FBE & FBF) when the Australian
Department of Civil Aviation confirmed its earlier warnings to KSAS that
it would not approve any more agricultural aircraft with wings of wooden
glued structure.
Having
proven the concept, the KSAS directors decided to form an associated company
to specialise in developing the design into a modern agricultural aircraft.
It would have a metal mainplane and tailplane and be powered by a current
American flat-six engine: from this concept the YA-1 was designed.
The
new company Yeoman Aviation Pty Ltd was established
effective 8 August 1958, during a company restructure of Kingsford
Smith Aviation Service Pty Ltd. The prime KSAS business had been the Australian
Auster dealership, importing almost 300 new Austers from Britain. But
that market had been lost to new Cessnas. New associate companies were:
- Austerserve
Pty Ltd: Auster sales and service. Managing Director J.T.Brown
- Yeoman
Aviation Pty Ltd: develop agricultural aircraft: Directors J.T.Brown,
P.G.Brown, C.W. Smith
- Kingsford
Smith Flying Service Pty Ltd, an associate company since 1951 operating
a successful flying school at Bankstown
A
new design single-unit metal wing duplicated the dimensions of the CA-6
Wackett's wooden mainplane but reduced the empty weight by 200 pounds.
The Wackett's rounded wingtips and slots were deleted but the fabric-covered
wooden ailerons were retained. The windscreen, canopy and turtledeck were
of new design and extensive use was made of fibreglass, then new to aircraft
construction, including engine cowlings, lower fuselage forward of the
wing, front and rear turtledeck, dorsal fin and removable rounded wingtips.
The new design 145 gallon hopper was also made from fibreglass.
Twenty
Yeoman YA-1 Cropmasters were constructed in the Yeoman Aviation hangar
at Bankstown between 1960-1966 with constructor's numbers 101 to 121 (c/n
109 was not completed). It was a new design, using a new metal making
much use of fibreglass panels, using American horizontally opposed 250hp
Lycoming or Continental engines. At first the basic structure was the
CA-6 fuselage frame, but as Yoeman production continued the use of Wackett
parts was reduced.
The
initial engine chosen was the 250hp Lycoming 0-540A engine with a Hartzell
constant speed propeller. The stainless steel exhaust augmenter tubes
to provide engine cooling did away with the need for cowling flaps, and
became a distinctive identification feature of the aircraft.

The first YA-1 c/n 101 was test flown at Bankstown on 15 January 1960,
flown by Peter Brown. Yeoman Aviation was under-capitalised which restricted
their ability to develop a new metal tailplane at the same time as the
metal wing was being designed and tested. DCA were persuaded to allow
the early YA-1s to enter service fitted with CA-6 Wackett wooden tailplanes.
A fibreglass dorsal fin disguised the shape.
When
the new metal tailplane design featured a stabilator, attractive swept-back
fin and large rudder. The first unit was testflown on a Wackett Trainer
VH-CYB in December 1961 and January 1962, then the fuselage frame and
new tailplane of that test Wackett was used to construct the next production
YA-1 c/n 106 VH-CYW which first flew 13 April 1962 as the first Cropmaster
250 with the metal tailplane.
DCA
had delayed full Type Approval waiting on further operational experience,
and the metal tail unit. After flight tests of VH-CYW, the Type Approval
Certificate was issued in June 1962. As YA-1 production continued, CA-6
components were replaced by new-build units. By 1966 the only original
Wackett Trainer components remaining were the undercarriage structure,
comprising only 3% of the total airframe.

Airwork
Pty Ltd KS.3 at work in WA circa 1959 with Chief pilot Bill Boulden. Ben
Dannecker collection
This story
is one of conflicting aims of producing a low priced agricultural aircraft,
which gave better performance and payload to the DH.82 Tiger Moths then
in widespread agricultural use versus DCA concern with the strength of
the wooden wing and tailplane structure.
The KS.3
Cropmasters utilised the basic wooden CA-6 wing and tailplane of glued
plywood and spruce box spar with glued plywood covering on its wings and
empennage. In addition to DCA concern over the integrity of the glued
wood 15 years after manufacture, tests had shown agricultural chemicals
reacted with the glue resulting in deterioration of the joints.
KSAS founded
the associate company Yeoman Aviation Pty Ltd
to develop the concept to produce a more modern aircraft with metal wing
and metal tailplane, powered by the latest American engines. The result
was the YEOMAN CROPMASTER 250.
Twenty YA-1
Cropmaster 250s were built at Bankstown between 1960-1966. The CA-6 Wackett
Trainer fuselage frame was used as the basic structure at first but gradually
replaced by new-build structure. The first five YA-1s retained the Wackett
wooden tailplane, mounted on a newly designed metal main plane. A schedule
was implemented for delivered YA-1s to be returned to Yeoman Aviation
at Bankstown to have the new metal swept-back tailplane fitted. A "metalisation
program" was devised for the remaining KS.3 Cropmasters but accident
losses reduced their numbers and none were fitted with the metal wings
and tailplane.
The
following sequence shows the steps in the development of the YA-1. It
highlights the continual struggle with the Department of Civil Aviation
over the airworthiness restrictions being imposed on certain wooden structure
aircraft being used for agricultural flying. However frustrating it was
for the regulator, DCA can be seen to be sympathetic to the struggling
Yeoman Aviation, and allowed a series of dispensations to allow the KS.3
Cropmasters to continue in commercial operation while waiting to be replaced
by the new metal wing YA-1 Cropmaster range. Similarly DCA gave owners
dispensations against its Air Navigation Order cancelling the CofAs for
the first five YA-1s with wooden empennage, because of Yeoman Aviation
delays in manufacturing the new metal tailplanes.

C. W. (Bill) Smith of Kingsford
Smith Aviation Service Pty Ltd designed modifications to a
standard CA-6 Wackett Trainer to install a hopper in the front cockpit
area with the pilot sitting in a slightly raised position in the rear
seat. |
2.57 |
In preparation for the proposed agricultural use of Wacketts, KSAS
made a series of test flights with their Wackett
Trainer VH-AJB, flown by KSAS director
Peter Brown. Wacketts were flown from the front seat with only
basic controls in the rear. VH-AJB was evaluated for continuous flying
from the rear seat, an oil cooler was fitted to the Warner Scarab
engine to improve its durability for extended operations. A wooden
propeller and alternative pitot locations were also evaluated. |
3.57 |
Wackett Trainer VH-AJH owned by KSAS
was modified at Bankstown with an agricultural hopper installed in
the front pilot position. Pilot controls and instrumentation were
moved to the rear seat, with the original windscreen and overturn
pylon moved rearward. This was later designated as
Kingsford Smith KS.1 |
26.3.57 |
VH-AJH first test flight at Bankstown by Peter Brown. It had been
painted in a special colour scheme of yellow, black and white.
(Peter Brown’s pilot log book states 26.3.57. VH-AJH airframe log
book states 28.3.57) |
4.57 |
VH-AJH modified to evaluate different hopper configurations. |
4.4.57 |
VH-AJH commenced a series of performance test flights by Peter Brown
who was required by DCA to wear a parachute. In one flight it carried
a 650 pounds payload for 20 minutes. Last flight in this series of
tests was on 26.7.57 |
7.57 |
VH-AJH forward fuselage was extended by approximately 8 inches to
maintain Centre of Gravity. Pilot seat and control lines were modified,
flap motor removed and a new hopper with louvre box was fitted in
the front cockpit area. This version was designated
Kingsford Smith KS.2
|
7.57 |
KS.2 VH-AJH was flown at Bankstown by W. G.
(Bill) Boulden, Director and Chief Pilot of Airwork Pty Ltd,
Perth WA. He was impressed by the potential but requested KSAS to
move the hopper behind the pilot to improve forward visibility and
reduce superphosphate and chemical spray on the windscreen. It
was indicated that if Boulden was satisfied with the new design, an
order for up to six aircraft could be expected. |
9.8.57 |
Wackett Trainer VH-AMA
was purchased by Bill Smith from a Melbourne owner. An airworthy
Wackett was urgently needed to modify and flight test a new cockpit
canopy design for the hopper in the rear seat position, as per Boulden's
request. The rear cockpit canopy was deleted and the rear fairing
moved forward to the hopper section. On completion of tests,
VH-AMA was restored to a stock Wackett Trainer two-seater configuration
and sold. |
8.57 |
KSAS commenced submitting engineering drawings and design strength
calculations to DCA for formal approval for the conversion of a number
of CA-6 aircraft to agricultural operations. |
9.57 |
DCA wrote to KSAS formally advising them of airworthiness concerns
for glued plywood structure aircraft on agricultural flying and expected
that in the future certain wooden aircraft could be restricted. The
CA-6 had a glued plywood and spruce wing box spar and glued plywood
covering on its wings and empennage (tailplane).
DCA memo states "KSAS stated that their submissions
were for an order from Western Australia for 6 aircraft and their
client wanted all aircraft or none at all." |
10.57 |
KSAS commenced modifications to Wackett Trainer A3-65 c/n 299 taken
out of storage. It was fitted with an 80-gallon aluminium hopper in
the rear position and revising the control systems to accommodate
the hopper outlet. A different cockpit canopy design was installed,
similar to that trialled on VH-AMA, but with a new rear fairing with
side windows and hinged for a rearward facing seat for a loader driver
or passenger. Registration VH-FBD was issued and this design was designated
Kingsford Smith KS.3 Cropmaster.
Bill Smith chose the name Cropmaster from a popular David Brown tractor.
He also decided on a standard KS.3 colour scheme of green and grey,
based on contemporary Austin Freeway car range. |
29.11.57 |
KS.3 Cropmaster VH-FBD first flown
at Bankstown by Peter Brown |
29.11.57 |
KSAS requested 10 registrations VH-FBD to VH-FBM be allocated to
the agricultural Wackett conversions. Internal memos within DCA show
a high level of concern regarding the strength of the CA-6 wooden
wings and tailplane if used for low-level agricultural work.
The requested registrations were nevertheless allocated. |
11.57 |
KSAS converted a second stored Wackett A3-131 c/n 365 to KS.3 Cropmaster
VH-FBE |
17.12.57 |
KS.3 Cropmaster VH-FBE first flown
at Bankstown |
12.57 |
Bill Boulden purchased two KS.3s for Airwork Pty Ltd, Perth WA |
1.58 |
DCA Head Office Airworthiness Branch had not shared the agricultural
Wackett developments with the DCA WA Regional office in Perth, where
they were to be based. DCA Perth office cabled Head Office asking
for information: "Airwork Pty Ltd, Perth advise that KSAS
has two CA-6 converted for agricultural use, with CofA, which they
previously had agreed to buy provided they met full DCA requirements."
|
10.1.58 |
DCA Head office replied: "First two will be granted CofA
and CofR. They will be accepted for their Airwork Licence. Investigations
proceeding re the other four aircraft but indications are that we
are committed to accept them." |
10.1.58 |
KS.3 Cropmaster VH-AJH test flown
Bankstown after modification to KS.3 standard
|
17.1.58 |
KSAS suffered a major setback when a fire at night in a closed hangar
at Bankstown destroyed KS.3 VH-FBD and the Kingsford Smith PL-7 Tanker.
The other KS.3 VH-FBE, the next KS.3 under conversion VH-FBF and the
test Wackett VH-AMA were also damaged. Investigation found the fire
had been deliberately lit. |
17.1.58 |
VH-AJH departed Bankstown for a week of extensive agricultural flying
at Armidale, Tamworth and Walcha |
11.2.58 |
Letter to DCA from J.T. Brown, Managing Director of KSAS referring
to the hangar fire damage: "VH-FBD has been written off by
us, however we would like to retain the registration for future use.
VH-FBE is being reconditioned and returned to service." |
21.2.58 |
KS.3 Cropmaster VH-FBF first flown
at Bankstown |
14.3.58 |
First sale of a KS.3 when VH-FBF was handed over at Bankstown to
Bill Boulden of Airwork Pty Ltd. Boulden flew it to Perth. |
7.5.58 |
Letter to DCA from J.T.Brown of KSAS: "We have orders for
ten KS.3 Cropmasters and two more orders pending. KSAS plans
to design a metal wing and we request that these K.S.3 aircraft be
allowed to operate with the wooden empennage units for a period of
not less than 12 months from the date of issue of the respective Certificates
of Airworthiness, when we will fit metal components." His
letter went on to outline plans for installation of Lycoming or Continental
flat 6 engines with a target date of June 1959. |
6.58 |
DCA internal memos debate the advisability of allowing any more
CA-6 agricultural conversions retaining the original wooden wing and
tailplane.
"If we agree to the KSAS idea
of letting a number of wooden wing Wackett aircraft go into agricultural
operations, what guarantees do we have that satisfactory metal wings
will ever be produced, particularly when one considers the financial
standing of the firm. The final re-hash of the Wackett Trainer
proposed by KSAS is not a simple rebuild. It will constitute virtually
a new aeroplane and KSAS will have to conduct as much engineering
justification for it as CAC have done on the Wirraway to Ceres conversion.
|
6.58 |
KSAS converted a fourth stored Wackett A3-176 c/n 410 to KS.3 Cropmaster,
re-using the registration VH-FBD. |
27.6.58 |
KS.3 Cropmaster VH-FBD(2) first flown
at Bankstown |
9.7.58 |
VH-FBD & FBE were demonstrated as top dresser and sprayer respectively
at an aerial agricultural conference at the Hawkersbury Agricultural
College NSW |
11.7.58 |
DCA wrote to KSAS agreeing to their 7.5.58 proposal, but stating
that no wooden tailplane Cropmaster will be allowed on agricultural
operations after 30 June 1959. Annual CofA renewals would be endorsed
"Not eligible for renewal with wooden empennage".
(Dispensations against this order
were later to be granted by DCA because of delays in producing the
new design metal tailplane and in fact the first five YA-1 Cropmasters
were delivered with original Wackett wooden tailplanes)
|
14.7.58 |
KS.3 VH-FBF sold to Airwork Pty Ltd, Perth. Bill Boulden departed
Bankstown two days later on ferry flight to WA. |
.58 |
DCA WA Region complained to Head Office that the Region’s officers
were caused "acute embarrassment" when Boulden brought the
two KS.3s to WA. These aircraft had been given dispensations to operate
contrary to the Department's stated policy on glued wood structure
aircraft. |
8.8.58 |
KSAS formed an associate company Yeoman
Aviation Pty Ltd, Bankstown Airport, Sydney.
Directors were John T. Brown, Peter Brown and
Bill Smith, Chief Inspector was Jack McConnell and the first
licenced engineer was Noel Hall.
Yeoman was to specialise in the production and marketing on agricultural
aircraft, in particular to develop the KS.3 Cropmaster to a modern
design. Yeoman was also to manage the "metallisation program"
to retrofit the KS.3s with metal wings and tails. Included in the
assets of the newly formed Yeoman Aviation transferred from KSAS were
the KS.3 VH-AJH and the majority of stored Wackett Trainer airframes. |
10.58 |
DCA approved a KSAS submission for a 2.5 inch extension to the
aft Centre of Gravity limit for CA-6 Wacketts provided they had the
following modifications:
- KSAS reduced wing and tailplane incidence mod
- wing slots covered
- single pilot controls only |
12.58 |
Yeoman Aviation commenced design work
on the proposed YA-1 Cropmaster 250.
Designers engaged for the YA-1 project were Brian Wager and Mick Burns.
The YA-1 was based on CA-6 metal fuselage frame and wooden tailplane,
a new design metal wing, powered by a 250hp Lycoming 0-540-A engine
with a Hartzell constant-speed propeller. |
|
To reduce development costs, Bill Smith instructed Brian Wager
to design the metal wing to the same dimensions as the CA-6 wooden
wing but without the rounded wing tips and slots. Like the CA-6, the
new wing was one-piece, but slotted flaps replaced the split flap
to improve short-field performance.
A new fuselage design made extensive use of fibreglass, still new
to aircraft construction, including the 145-gallon hopper. Other fibreglass
components were engine cowling, turtledeck and dorsal fin fairing,
canopy top, lower forward fuselage.
The early production YA-1s retained the CA-6 wooden tailplane and
fabric covered rear fuselage. |
59 |
Early 1959 C.W. Smith and W.G. Boulden bought
out J.T. Brown and P.G. Brown’s interest in Yeoman Aviation
Pty Ltd:
Managing Director: Bill Smith
Operations Manager: Bill Boulden
Technical Director: Brian Wager |
3.59 |
Bill Boulden had sold his shares in Airwork Pty Ltd and established
his own company named Air
Culture Pty Ltd, Perth. |
3.59 |
Air Culture purchased KS.3 VH-FBE, which was ferried from Bankstown
to Perth 3.59 |
|
Bill Boulden wrote to DCA: "Air Culture is engaged on aerial
spraying and topdressing in WA and will operate three CA-6 Cropmaster
aircraft during the current season. Air Culture is also the major
shareholder in Yeoman Aviation Pty Ltd of Bankstown and is the WA
agent for this company which was formed recently to develop the CA-6
aircraft." |
5.59 |
KS.3 VH-AJH leased by Yeoman Aviation to Air Culture Pty Ltd, Perth
WA |
15.5.59 |
KS.3 VH-AJH test flown at Bankstown after its CofA was renewed.
Spray equipment was installed before it departed Bankstown on ferry
to WA on 24.5.59 |
20.6.59 |
Work commenced on constructing the first YA-1 Cropmaster 250 at
Bankstown, c/n 101 |
12.59 |
Air Culture placed an order with deposit for a KS.3 metal wing
conversion to be ready in June 1960 under Yeoman's metallisation
program. However progress was slow because of pressure of work
on the new YA-1 Cropmaster 250s. DCA granted a dispensation for KS.3s
VH-FBD & FBF to continue to operate in WA until 31.12.60 by which
time they will be required to be fitted with metal wings.
(Compiler’s note: It is assumed the metal empennage for the KS.3s
was the identical unit being designed for the YA-1s. In the event,
no KS.3 received a metal tailplane) |
59 |
Two Albury NSW based operators placed orders for YA-1 Cropmaster
250s before the type had flown: Air Spraying & Spreading, and
Marshalls Spreading Service |
15.1.60 |
First flight of prototype YA-1 Cropmaster
250 c/n 101, pilot Peter Brown
Commenced an extensive performance flight testing for DCA certification |
2.60 |
W.G. Boulden is Managing Director of Air Culture Pty Ltd, and Operations
Manager of Yeoman Aviation Pty Ltd, Sydney.
Air Culture now had all four surviving KS.3 Cropmasters, which were
operating in WA under a DCA Airwork Licence in the name of Yeoman
Aviation. |
8.60 |
DCA WA Region advise Head Office that they are "agreeably surprised"
at the good condition of the Wackett Cropmasters after two seasons
of agricultural operations in WA |
10.60 |
W. G. Boulden wrote to DCA: the contracted fitting of metal wings
to Air Culture KS.3s scheduled for June 1960 has been delayed. "It
now appears the metal wings will be ready for FBE in May 1961. The
remaining three aircraft will be converted as soon as production of
the metal components allows."
DCA granted another dispensation for KS.3s to continue to operate
on agricultural operations, extending the deadline to be converted
under the approved Yeoman Aviation metallisation program until
31.12.61. |
11.60 |
First flight of second YA-1 Cropmaster
250 c/n 102.
This aircraft had a modified main wing spar, which was used on all
following YA-1s. The modification made no change to the AUW 3250 lbs.
Delivered that month as VH-MSS |
24.11.60 |
The first two Cropmaster 250s VH-BJF & MSS flew demonstrations
for two days at an agricultural aviation conference at Wagga NSW |
60 |
DCA promulgated an Air Navigation Order prohibiting the use of aircraft
of glued-wood construction on agricultural operations after 31 December
1961. This affected the KS.3s and the YA-1s with wooden empennage. |
60 |
Jim Hazelton of Hazair Agricultural Service Pty Ltd, Orange NSW
and Hazair Sales & Service Pty Ltd became closely involved with
Yeoman Aviation as a salesman and pilot.
Later Jim Hazelton and his brother Max
of Hazelton Air Service, Cudal NSW held a financial interest in
Yeoman Aviation.
In July 1966 Max was quoted as saying that two years earlier he held
a financial interest in the Cropmaster but terminated it because he
considered there were design deficencies which he outlined. |
17.2.61 |
First flight of third YA-1 Cropmaster
250 c/n 103.
Delivered to Jim Hazelton’s Hazair Agricultural Service, Orange NSW |
61 |
Yeoman Aviation developed the all-metal tail unit to replace the
wooden Wackett tailplane retained on the first five YA-1s. Brian
Wager’s design was similar to the PA-24 Comanche, an all-flying tailplane
with swept fin and rudder. |
5.6.61 |
First flight of fourth YA-1 Cropmaster
250 c/n 104.
DCA internal memo same date: latest YA-1 Cropmaster has been completed
at Bankstown with the original wooden tailplane and is ready for issue
of CofA. The Department agrees to issue of CofA for 12 months, after
which metal empennage must be installed. |
7.61 |
Flight trials of the metal tailplane commenced at Bankstown using
Wackett Trainer VH-AIV which was
rebuilt by Yeoman Aviation, fitted with the prototype swept YA-1 metal
tailplane. It retained the Warner Scarab radial engine, fabric covered
rear fuselage and wooden wing with clipped wingtips. YA-1 Cropmaster
canopy and raised turtle deck were installed to test the aerodynamic
effect on the new tailplane. This hybrid Wackett Trainer was allocated
registration VH-CYB for the test flying, and designated by Yeoman
as type Yeoman
175. |
10.61 |
First flight of fifth YA-1 Cropmaster 250
c/n 105. The last delivered with wooden tailplane. |
10.61 |
Air Culture wrote to Yeoman Aviation confirming their order for
a second YA-1 (VH-CYW), and stated that their first KS.3 for metal
conversion will arrive at Bankstown on 26.10.61.
However the metal wing was not ready and no KS.3 flew from WA. |
19.12.61 |
Wackett VH-CYB first test flight with the
new metal Cropmaster tailplane. Pilot Peter Brown. 30 hours
of flight trials of the metal tailplane continued until 1.62, flown
by Peter Brown and Jim Hazelton. |
29.12.61 |
Bill Boulden wrote to DCA advising that metal wings for KS.3s VH-AJH
and the damaged VH-FBD are still not ready due to delays by Yeoman
Aviation. He urgently requested approval for AJH to continue in agricultural
operations until 31.3.62 for important spraying in the Jerramungup
district. The other three Air Culture KS.3s had been damaged in accidents.
DCA granted yet another extension until 31.3.62. |
21.3.62 |
Bill Boulden again requested an extension to CofA for KS.3 VH-AJH
because of the crash of Air Culture's Cessna 180 VH-KIH combined with
delayed delivery of their second YA-1 VH-CYW.
DCA granted yet another extension until YA-1 VH-CYW had been delivered
to Perth. |
22.5.62 |
The last remaining KS.3 VH-AJH was retired
from agricultural flying by Air Culture. |
|
Aircraft magazine report July 1962: "Development
flying to test and prove the new tail unit was carried out in a specially
modified Wackett VH-CYB which flew approximately 30 hours in the hands
of Peter Brown and Jim Hazelton. The new tailplane gave complete satisfaction
and was eventually static tested to destruction to satisfy DCA requirements."
|
13.4.62 |
First flight of YA-1 Cropmaster 250 with
metal tailplane, C/n 106.
This was a newly built tailplane unit because the prototype tailplane
air tested on the Wackett VH-CYB had later been tested to destruction.
Test flown extensively by Peter Brown for DCA Type Certification during
April and May.
C/n 106 introduced improvements including:
- fabric covering the rear fuselage replaced by removable Alclad panels
- fibreglass tail cone
- fibreglass rudder and tailplane tips
- fibreglass protective panels for tailplane leading edge
- fibreglass protective panels on underside of flaps
- Dunlop wheels and disc brakes
- electric auxiliary fuel pump
- air scoops fitted to fuselage sides to supply frehs air to pilot
and pressurise the cockpit to restrict ingress of superphosphate dust
and chemicals |
6.62 |
DCA issued Type Certificate for the YA-1
Cropmaster 250 and 250R.
The Type Certificate included Hartzell or McCauley propellers. |
6.62 |
Aircraft magazine report: Yeoman Aviation has received
enquiries from NZ, Argentina, Rhodesia and West Germany. They are
planning an extended production run, completing Cropmasters at a rate
of one a month. When existing stocks of CA-6 Wackett Trainer fuselage
frames have been used, Yeoman will construct this component themselves.
|
62 |
During the year, the three remaining YA-1s
in service with wooden tailplanes were returned to Bankstown to
have the metal tailplane installed by Yeoman Aviation.
First was VH-CXS from Hazair, Albury, then VH-CXQ flown from Perth
in June 1962. Last was VH-TSD from Adelaide, which was first flown
at Bankstown 22 November 1962 with the new tail. |
62/64 |
Yeoman Aviation purchased Wackett Trainer fuselage frames and parts
from many sources when the original stocks obtained from KSAS were
used in Cropmaster production. An example was the dismantled VH-AJU
at Parafield which was moved to Sydney in 1962 |
9.62 |
YA-1 Cropmaster 250 c/n 108 completed for export to New Zealand.
This and subsequent production YA-1s had a modified main spar permitting
an increase in AUW 3,250 lbs to 3530 lbs, allowing a significant increase
to agricultural payload. |
1.63 |
Executive Air Services, Essendon Airport, Melbourne have sub-contracted
for the manufacture of the YA-1 metal tailplane. The ribbed
rudder panels were supplied by Victa Consolidated Industries, and
other parts manufactured by Toowoomba Foundry (Southern Cross Aviation)
|
1.4.63 |
Yeoman Aviation purchased CA-6 Wackett Trainer
VH-AKF from a Melbourne owner and it was flown to Bankstown
and struck-off the Register the same day. Appears to have been used
as a static test aircraft, fitted with a YA-1 cockpit and rear turtledeck.
By January 1964 it was retired, engineless out on the grass at Bankstown. |
.63 |
Bankstown engineer Don Cameron bought
out Jim and Max Hazelton’s interest and gained control of the company.
It was recapitalised under name Yeoman Aircraft Pty Ltd.
Don Cameron was an experienced aircraft engineer. To improve efficiency,
the new company diversified its operations, taking on maintenance
and modifications to other agricultural aircraft.
Chairman and Managing Director: Don Cameron
Director in charge of production: Bill Smith |
4.63 |
Yeoman Aircraft modified two PA-25 Pawnees to provide faster load
dumping in emergencies. |
63 |
Don Cameron announced that customers of new
YA-1 Cropmaster 250s would have a choice of Lycoming or Continental
engines in future. All subsequent aircraft were completed
with the fuel-injected Continental IO-470 engines. The cowling
had different air intake and minor internal mods were required for
the CofG change due to the 40lb increase in weight of the Continental. |
12.3.64 |
Cropmaster 250 VH-TSD was test flown
at Bankstown, the first to have Continental IO-470 installed,
during an overhaul by Yeoman Aircraft at Bankstown and retrofit with
a Continental IO-470-G. VH-TSD was redesignated Cropmaster
250R |
3.64 |
First production YA-1 completed with Continental
IO-470G c/n 113. All subsequent production was fitted with
the Continental engine, model designated Cropmaster
250R |
3.64 |
Yeoman Aircraft were building large fibreglass underwing fibreglass
hoppers, and installing them in Cessna 180s, example VH-DEJ |
64 |
Don Cameron wanted 260hp Continental IO-470-E engines but Continental
dealers for Australia, Rolls Royce would not supply them to Yeoman.
The IO-470-Gs suffered from overheating problems. Later
Rolls Royce did supply IO-470-Rs for late production aircraft.
A number of Cropmaster 250R operators were to retrofit IO-470-Es themselves. |
.65 |
Don Cameron purchased Bill Smith’s shareholding.
Yeoman Aviation Pty Ltd was reorganised with new name Cropmaster Aircraft
Pty Ltd, Managing Director Don Cameron. |
14.7.65 |
NZ agents Southern Aviation announced they
had formed an associate company named Cropmaster (NZ) Ltd to distribute
YA-1s in New Zealand |
8.65 |
YA-1 Cropmaster 250R Series 2 was introduced,
undercarriage mounts moved 2 inches further forward of the mainspar
to correct the tendency to nose over on the brakes. Introduced from
c/n 117 onwards. |
65 |
Yeoman offered as a YA-1 optional modification 12 inch wing tip
extensions to improve lift to prevent aircraft squashing down into
crop during low-level spraying |
1.66 |
Final YA-1 Cropmaster c/n 121 built at Bankstown,
a total of 20 built. The previous
aircraft c/n 120 remained unsold at Bankstown until Don Cameron finalised
its sale to NZ in 12.66 |
3.66 |
Don Cameron is rebuilding his DH.82 Tiger Moth VH-AJA at Bankstown
for his personal use |
66 |
By now the only original Wackett trainer
components incorporated in the YA-1 is the undercarriage structure,
comprising only 3% of the total airframe |
4.66 |
Four Australian aircraft manufacturing businesses applied to the
Government Tariff Board for a bounty or tariff protection for their
products to compete with foreign imports:
Cropmaster Aircraft Pty Ltd, Bankstown: YA-1 Cropmaster
Victa Ltd, Sydney: Airtourer 100 & 115, Aircruiser
Transavia Pty Ltd, Sydney: PL-12 Airtruk
Aerostructures, Bankstown: SA-29 Chipmunk Spraymaster/Sundowner |
6.66 |
Tariff Board interim decision refused restrictions on the importation
of competing aircraft types, resulting in Cropmaster Aircraft and
Victa Ltd announcing that they were forced to cease aircraft production. |
8.66 |
Cropmaster Aircraft Pty Ltd accepted a formal proposal to sell their
manufacturing plant and design rights for the YA-1 to Donald Gray,
Plastidyne Manufacturing Co, Los Angeles. A partnership was
announced, named Cameron Gray Aircraft Co, Gardena,
Los Angeles California. The new company plans to continue building
the Cropmaster line in USA. Don Cameron is a Director and will handle
the Australian and NZ marketing of US built Cropmasters. |
29.12.66 |
A crate containing a set of parts for a complete YA-1 airframe,
plus additional parts, was loaded on a truck at Bankstown Airport
for shipping to USA. Consignment on the side of the crate was
marked:
"Cameron Gray Aircraft Co, Plastidyne Manufacturing Co, 1500
West 139 Street, Gardena, California, USA" |
|
Fuselage frames of c/n 122 and 123 were shipped to California, along
with jigs |
1.67 |
Australian Flying magazine report: John Cameron says two
complete YA-1s could be built "in a hurry" from the components
shipped to USA. The plan is to assemble two Cropmasters in California
to assess the US market before a decision is made on future production.
Manufacturing methods would be different to reduce the 3,500 man-hours
taken to build a YA-1 in Australia. Plans include a more powerful
300hp version which could carry a 1400 pounds payload.
Cameron would be responsible for marketing the US built Cropmasters
in Australia. He expects that he and some of his staff will soon visit
California to help install the jigs sent to the Los Angeles plant,
and that he expected the first of the US built aircraft would be available
for sale back to Australia within 9 months. |
67 |
Cropmaster Aircraft Pty Ltd continued operations in their hangar
at Bankstown for a period, providing maintenance and modifications
to other aircraft. |
67 |
Cropmaster Aircraft Pty Ltd ceased operations
and company wound up |
|
Unsourced reports that one YA-1 was flown in USA, but registered
as an experimental home built type. In 1976 there was a report that
the first YA-1 in USA was still flying in Florida, fitted with a radial
engine. |

Troublingly, a photograph taken of A3-176 in RAAF olive drab paintwork
parked outside at Bankstown with engine removed, was reportedly taken
in late 1959.
- If that date is correct then -176 was not used as the basis for
VH-FBD's rebuild as a KS.3 despite KSAS quoting c/n 410
- More likely the photo was taken in 1957 when taken out of storage
prior to rebuild as VH-FBD |

KSAS carried out a series of modifications to VH-AJB to explore
performance improvements. The wing incidence was reduced to 3.25 degrees
by inverting the front wing attachment brackets, setting the tailplane
incidence at 3 degrees, covering the wing slots and removing the rounded
wingtips. A spinner was fitted to the propeller and exhausts relocated
to the underside of the engine. It retained the standard Wackett wheel
fairings.
KSAS reported that these modifications improved the climb and cruise
performance. Roll response and spin recovery were good. |
2.57 |
VH-AJB was used for a series of tests by KSAS in preparation for
the proposed KSAS agricultural modification of Wacketts. The type
was usually flown from the front seat with only basic controls in
the rear. VH-AJB was evaluated for continuous flying from the rear
seat, an oil cooler was fitted to the Warner Scarab engine to improve
its durability for extended operations. A wooden propeller and alternative
pitot locations were also evaluated in a series of test flights by
Peter Brown. |

Yeoman Aviation Pty Ltd have designed a new all-metal tail unit
to replace the wooden component inherited from the Wackett Trainer
in the early production YA-1 Cropmasters. DCA had withheld full type
approval for the YA-1 mainly because of concerns about the strength
of the wooden tailplane structure. The configuration decided on incorporated
an all-flying tailplane and a swept fin and rudder of modern appearance.
|
2.61 |
Yeoman Aviation requested DCA approval to test the new swept tail
for the YA-1 on a wooden wing Wackett Trainer "as the flight
test vehicle for the metal empennage. The aircraft has a Warner motor
but YA-1 windscreen, decking and hopper fittings." |
7.61 |
Rebuilt by Yeoman Aviation at Bankstown, fitted with the prototype
new design swept YA-1 metal tailplane. It retained the Warner Scarab
radial engine, fabric covered rear fuselage and wooden wing with clipped
wingtips. YA-1 Cropmaster canopy and raised turtle deck were installed
to test the aerodynamic effect on the new tailplane.
This hybrid Wackett Trainer was designated
by Yeoman as type Yeoman 175.
|
|
Reported at the time that this aircraft will also be used to test
a nosewheel design for the YA-1, but not in fact carried out. |
61 |
Allocated registration VH-CYB: Used byYeoman Aviation
at Bankstown for test flying to evaluate metal YA-1 tailplane. |

First testflight Bankstown, with VH-CYB painted on both wings but
not on sides. Pilot Peter Brown |

Test flying program completed. VH-CYB was Not Taken Up. |
|
Aircraft magazine report July 1962:
"Development flying to test and
prove the new tail unit was carried out in a specially modified
Wackett VH-CYB which flew approximately 30 hours in the hands of
Peter Brown and Jim Hazelton. The new tailplane gave complete satisfaction
and was eventually static tested to destruction to satisfy DCA requirements."
|
1.62 |
AHSA Journal January 1962:
Reported that the Wackett test aircraft for the metal tailplane now
has its wooden wing removed at Bankstown and is due to be fitted with
a YA-1 metal mainplane. The Scrab radial has been replaced by a Lycoming
engine. This Wackett was then rebuilt as YA-1
Cropmaster 250 c/n 106 which became
VH-CYW and first flew at Bankstown 4.62 as the first YA-1 fitted with
new metal tailplane. |
