Overview
A pilot was performing touch-and-go landings on runway 13 during a training flight. After several circuits, the pilot decided to execute another touch-and-go on runway 5. The pilot reported extending the landing gear on the downwind leg and receiving a safe gear indication. However, upon touchdown, the aircraft settled onto the runway with the landing gear still retracted.
Pilot Statement
The pilot stated that no warning horn sounded when the throttles were retarded to idle just prior to touchdown. The aircraft came to rest on the runway surface, sustaining damage to the lower fuselage and propeller.
Examination Findings
Post-accident examination of the aircraft revealed no pre-impact mechanical issues with the landing gear system itself. The landing gear had been properly extended and locked as indicated, but the gear warning horn failed to activate. Investigation traced the malfunction to a defective micro-switch and a broken electrical wire within the warning horn circuit, rendering it inoperative.
Conclusion
The aircraft was landed with the landing gear retracted despite the pilot believing it was extended. The gear warning horn was inoperative at the time of the approach. No further causal factors were identified.
