Incident Overview
A pilot undergoing instruction for upgrade to pilot-in-command (PIC) status was conducting training in the type of airplane. The aircraft remained in closed traffic to practice various types of approaches. On the sixth and final landing, the crew was simulating a short field landing over a simulated 50-foot barrier.
Landing Gear Malfunction
During the landing gear extension, the gear circuit breaker popped due to an overheated landing gear motor. This interruption left the landing gear in a partially extended state.
Crew Actions and Outcome
The crew failed to verify the position of the partially extended landing gear. Upon touchdown, the landing gear collapsed, resulting in damage to the aircraft.
Conclusion
The accident occurred during a training maneuver when the landing gear had not fully extended and the crew did not confirm its status before landing.
