Operational event involving a Robinson R22 Beta, VH-JDB, Ban Ban Springs, NT on 20 October 1994

The pilot landed the helicopter in long grass leaving the engine at idle power. Hot exhaust gas emissions from the exhaust tail pipe ignited the dry grass, engulfing the helicopter in flames. The pilot attempted to take-off but the engine appeared not to respond. Both the pilot and passenger received minor burns as they vacated the helicopter, which was damaged by fire. The helicopter exhaust system appeared to have been modified with an extension welded to the tail pipe which directed the hot exhaust gases towards the ground. There did not appear to be any reported problems with the engine.
