Navy. In 1980 the thriving general aviation division was separated as Hawker Pacific but both companies remained part of Hawker Siddeley. In 1981 HdH formed the Australian Aircraft Consortium with CAC and GAF to design and manufacture the A10/A20 Wamira. The project suffered numerous delays and cost increases (due in part to the changing requirements of the RAAF and in part to the inexperience of the consortium members in designing to military requirements) and shortly after the prototype was completed at HdH's Bankstown factory the programme was cancelled at the end of 1985. Earlier in 1985 HdH purchased CAC, which was initially kept as a separate company but was then renamed Hawker de Havilland Victoria (HdHV) the following year. At the time of the purchase both companies were in the initial stages of producing components for the GAF-built version of the F/A-18 Hornet. HdH at Bankstown was responsible for the landing gear and major hydraulic system components including aileron, rudder and flap actuators and hydraulic fluid reservoirs; while CAC/HdHV was responsible for the wing pylons, engine access panels, aft nozzle fairings, aircraft-mounted accessory drive gearboxes and engines. Building aircraft again Following the cancellation of the Wamira, HdH resumed production of complete aircraft in 1987 after it was selected to build a version of the Pilatus PC-9 under licence for the RAAF. HdH was responsible for final assembly of 65 aircraft (known as the 'PC-9/A'), initially from kits supplied by Pilatus (17 aircraft), but with the components for the final 48 examples produced by HdHV and GAF (which by this time had been privatised and renamed Aerospace Technologies of Australia) (ASTA). Two Swiss-built PC-9s were already delivered in 1987. The last Australien-made PC-9/A was delivered in May 1992. In May 1988 HdH delivered the first Bankstown-assembled Sikorsky Black Hawk to the RAAF. After eight had been built the RAAF's helicopters were transferred to the Australian Army; HdH deliveries continued to the Army until the last of 38 locally assembled aircraft was delivered in January 1991. In March the following year the last PC-9/A was delivered. Also in 1992 HdH was de-listed from the Australian Stock Exchange when it was sold to BTR Nylex. The PC-9/A was the last complete aircraft type to be built by HdH, although RAAF Caribous could still be seen at Bankstown until 1994. During the same time period HdH was involved in the McDonnell Douglas Helicopters MDX
