Event Details
The aircraft was operating a charter flight for the BHP Cannington mine. The flight departed from Townsville at 0630 EST and arrived at Cannington at 0840 without incident. After landing, the aircraft was refueled. At approximately 0945, seven passengers and baggage were loaded. The aircraft was then started and taxied for runway 36, during which time the necessary checks were completed.
Engine Failure and Forced Landing
Takeoff was commenced, and after becoming airborne with a positive rate of climb, the pilot selected the landing gear up. While the gear was in transit, a sudden power loss occurred from the left engine. The pilot reported a simultaneous loss of height, roll, pitch, and yaw, accompanied by a sound similar to a buzz saw from the left engine. Recognizing the left engine failure, the pilot attempted to maintain speed and directional control. Power was reduced on the right engine to maintain directional control. The pilot intended to land the aircraft with the gear retracted beyond the end of the runway. However, the left wingtip struck a steel fence post, causing the aircraft to spin to the left. The aircraft then struck a low earth bank while traveling sideways and rearwards.
Evacuation
After the aircraft came to rest, all windows were obscured, and the pilot believed the aircraft was on fire. The pilot attempted to open the main cabin door but was unsuccessful. Passengers were then evacuated through the emergency exit.
Probable Cause
According to the official findings, the retaining bolts for the propeller gearbox stationary gear assembly failed when the aircraft had just become airborne. The pilot was unable to maintain directional control and landed the aircraft with the landing gear retracted.
