The Historical Aircraft Restoration Society, often referred to by its acronym, HARS, is an Australian-based aircraft restoration group. The group has two museums, at Shellharbour Airport and Parkes Airport in New South Wales, Australia. HARS was formed in 1979 by a group of aviation enthusiasts interested in the preservation of Australian Aviation History. Its mission is "To recover and where possible restore to flying condition, aircraft or types of aircraft that have played a significant part in Australian Aviation History both in the Civil and Military arenas".
