Wheels up landing involving a Cessna 172RG, VH-KPL, Cairns, Queensland, on 3 April 1993

After the pilot selected the landing gear down, no gear locked down indication was received. The pilot elected to remain in the circuit area and attempted to rectify the problem. He observed that the right main gear was "dangling" and attempts to lower it by both the normal and emergency methods were unsuccessful.

After about 45 minutes when no solution could be found the pilot was advised that a landing with the landing gear retracted was the recommended course of action. The aircraft was subsequently landed on runway 12 with the gear retracted.

Inspection of the landing gear system found that a casting attached to the right gear actuator had failed. As a result, the right gear leg could not be driven to the down position.
