Crashed at Sturt Meadows Station, 55 km WNW of Leonora Airfield, Western Australia, between Leonora and Meekatharra, at approximate co-ordinates Latitude 28°48' S, Longitude 120'43' E. The pilot and nine passengers were killed and the aircraft was destroyed by the impact and a subsequent fire.
The ATSB report concludes that the aircraft probably accrued icing on the airframe, which caused the airspeed to decrease to the point where the aircraft stalled and entered a spin; and that the pilot did not become aware of the decreasing airspeed in time to take action to prevent loss of control
The crash of VH-BBA was the worst air accident in Western Australia for 20 years, killing all 10 aboard, and worst MU-2 crash in the world, in terms of number of fatalities. The ATSB report notes that there was a "Death Threat" made against one of the passengers, but dismissed this as a factor, stating that there was no evidence that the aircraft had been sabotaged or tampered with.
The crash of VH-BBA was the first of a spate of accidents - four in all - involving MU-2s that occurred in Australia between 1988 and 1994, all caused by icing on the airframe which caused the airspeed to decrease to the point where each aircraft stalled and entered a spin. Three of the four crashes resulted in fatalities.
