Collision with terrain involving a Piper Aircraft Corp PA-31T, VH-CCW, PERTH WA 4N, WA on 3 May 1981

The pilot was completing an air test following work on one propeller. During the base leg for runway 21 at Perth the aircraft appeared to stall and the pilot did not regain control. It crashed in the back yard of a house in Bassendean causing some roof damage. The out-of-control descent was described as a "falling leaf" indicating the aircraft had little forward speed. Also there was no wreckage trail. The aircraft caught fire on impact. The reason for the loss of control was not determined however, the post-mortem examination of the pilot indicated a possibility of incapacitation resulting from heart failure.
