In 1970 HdH entered a new phase when it began to pursue subcontract work for civil airliner manufacturers. This work is now the main focus of the company and HdH has manufactured components for many of the major airliners of the later part of the 20th century and the 21st century, including work for Boeing, Airbus and McDonnell Douglas. In 1976 HdH undertook the refurbishment of 16 ex-US Navy Grumman S-2G Trackers for the Royal Australian 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.
