The Lockhart River air disaster occurred on 7 May 2005, when Aero-Tropics Air Services Flight 675 crashed while on approach to land at Lockhart River Airport in Queensland, Australia, on a ridge known as South Pap 6 nautical miles (11 km) north-west of the airport. All fifteen on board died as the aircraft was completely destroyed by impact forces and subsequent fire. The Fairchild Swearingen Metroliner commuter aircraft, registered VH-TFU, was owned by Transair Ltd and operated by Aero-Tropics. The flight was scheduled from Bamaga on Cape York to the regional centre of Cairns, with a stopover in Lockhart River. It was the worst air crash in Australia in 36 years since MacRobertson Miller Airlines Flight 1750 on 31 December 1968.
