A Eurocopter AS355F-1 helicopter, VH-SEV, operated by Rotor Head, air taxied from the hangar to the maintenance facility at Bankstown Aerodrome, New South Wales with the pilot and one passenger on board.
After about 5 minutes in flight, the pilot commenced the landing. As the skids touched the ground, the pilot observed the right-hand engine chip light illuminate and smoke coming from the right-hand side of the aircraft. The pilot immediately shut down the right-hand engine. Mechanics from a nearby workshop ran out and extinguished the engine fire.
The aircraft sustained significant damage to the engine and minor heat damage to the surrounding structure.
Contributing factors:
A single third-stage turbine wheel blade failed due to fatigue cracking, resulting in secondary damage to the engine and total engine failure.
The rapid fatigue crack progression in the third-stage wheel was probably caused by a momentary dwell in the speed avoidance range.
