During the landing roll at approximately 65 knots, the aircraft began to veer to the left. The undercarriage position indicator still showed the gear down and locked, but the left wing then began to drop. By the time the left wingtip touched the ground, the left maingear green light had gone out and the landing gear warning horn activated. The aircraft skidded for about 200 metres with the left wingtip on the grass, and came to rest some 50 metres from the runway centreline. An inspection of the aircraft by the pilot after the accident revealed that the left main leg had detached completely from its mounting and the main pivot pin was missing.
