After completing parachute operations, the engine failed and the pilot conducted a forced landing at Moruya Airport.
The aircraft VH-AAX was modified in by Aerial Agriculture Co. Australia, and incorporates a longer fuselage, fin and rudder. All Australian mofifications.
During the lifespan it has been fitted with a radial engine, a Pratt & Whitney PT6 turboprop and also fitted with numerous Garrett TPE-331 turbine engines.
The aircraft is known correctly as the "Wallaroo 605" The '605' being the original horsepower rating of the first turbine fitted.
Contributing factors
• A low-cycle fatigue crack, which had initiated on the 3rd-stage turbine wheel, grew to a critical size liberating a fragment of turbine wheel. Following this, the engine failed, requiring the pilot to shut down the engine and conduct a forced landing.
• Errors in cycle counting made by a previous maintainer resulted in the 3rd-stage turbine wheel remaining in-service beyond the component life-limit.
