CESSNA TU206-A, VH-DGD, Bankstown NSW, 22 April 1990

The aircraft had taken off from runway 29R when, at a height of about 80 feet, the engine suffered a substantial loss of power. A forced landing was carried out onto a cleared area,beyond the end of the runway. The nosegear collapsed as the pilot attempted to groundloop the aircraft to avoid fences. Investigation revealed a non standard fuel strainer drain had been fitted in the fuel supply system between the fuel tank and the engine driven pump. Stress corrosion cracking caused failure of the strainer drain adapter fitting and allowed fuel to leak from the engine fuel supply. The diminished fuel supply was insufficient for the engine to maintain power.
