On 16 December 1988, at approximately 1015 hours a Mitsubishi MU-2B60 Marquais aircraft crashed on a Pastoral property 55 km WNW of Leonora Airfield, Western Australia. The pilot and nine passengers were killed and the aircraft was destroyed by the impact and a subsequent fire.

The report concludes that the aircraft probably accrued icing on the frame which caused the irespeed 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.

On 26 January 1990 at 0105 hours, a Mitsubishi MU-28-60 Marquis aircraft crashed approximately 10 km NNE of Meekatharra, WA. The pilot and passenger were both killed and the aircraft was destroyed by impact and a subsequent fire.

The 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; that the pilot was not previously aware of the ice formation; and that he did not take action to prevent the aircraft's speed from decreasing.
