Formed 1958 as an associate of Kingsford-Smith Aviation Service to specialise in development of agricultural aircraft. First prototype Yeoman YA-1 conversion of Commonwealth CA 6 Wackett trainer flew in 1960, followed by production versions: KS.3 Cropmaster 250 and Fieldmaster 285.
Aircraft
Yates Bi-Motor / Bi-Craft
The George Yates of Beaverton, Oregon, Oregon O was developed into the 1935 twin-engined Greenwood-Yates Bi-Craft (NC15546) with 50 hp engines.
Yates and partner Allan D. Greenwood (a pilot and Oregon state aircraft inspector) formed the North Pacific Aircraft Corp. to market the Bi-Craft geodetic-construction light twin design.
Yates Gilbert Experimental
In 1945, an updated Oregon O parasol was built. An open cockpit, midwing monoplane Oregon O was powered by a 125 hp Martin 4-333 inverted 4-cylinder, it had wooden geodetic basket-weave construction.
One was built, N15508, and possibly one other.
Yates Oregon O
Circa 1932 George Yates built the single-place, open cockpit, midwing monoplane Oregon O. Powered by a 40hp Salmson AD-9, it had wooden geodetic basket-weave construction. One was built, N15508, and possibly one other.
Yates Stiper
The two-place Yates Stiper of 1930 was built for Elmer Stipe. Registered N10657, it was originally powered by a 125hp Martin 333 and later refitted with a 90hp Cirrus.
The plane had two seats and a parasol wing.
It eventually flew 4,000 hours, carrying passengers.

Yakolev Yak-141
The Yak-141, being the world’s first supersonic STOVL (short take-off/vertical landing) aircraft, has three engines: one lift-cruise R-79 with a thrust of 15500kg and two small-sized RD-41 of 4100kg each. The powerplant allows the plane to lift off vertically with a weight of up to 15,800kg. Alternatively, the Yak-141 can perform short take-offs (60-120m) with a weight of up to 19,500kg. In the latter case the combat radius increases by 1.5-2 times and patrol time in the combat zone by two times. The pilot can use afterburner even when the nozzles are deflected. The Yak-141’s integral flight-control system sets power and deflection of the nozzles so as to optimise making vertical/short take-offs and landings.
The Yak-141 first flew in March 1989, piloted by Andrei Sinitsin.
The Yak-141M was meant primarily for ground-basing. Introduction of new flight regimes, as well as new take-off/landing techniques, has entailed changes in the airframe, leading to a new design, the Yak-141M.

Yakolev Yak-130 / AEM-130
Through a joint programme with Yakolev of Russia, Aermacchi is assisting in developing the Yak/AEM-130 to meet the Russian Air Force’s requirement to replace the L-29 and L-39. The aircraft is equipped with a quadruplex fly-by-wire flight control system and will be required to fulfil a broad range of tasks: from basic flying training to weapons training and aircraft carrier deck training. The aircraft are equipped with wingtip- and pylon mounted AAMs with a roulette and sensor pod also fitted.
The joint Italian/Russian Yak 130 technology development programme ran from April 1996 to December 1999, accumulating some 300hr flying. The two seat Yak-130 fighter/trainer was exported as the AEM-130.
The Yak-130 became all Italian in 1998 and served as a basis for the Aermacchi M-346.
