Incident Overview
A recent incident involved an aircraft that landed with its landing gear retracted. According to the pilot's statement, as he reduced the throttle for landing, the landing gear warning horn sounded. The pilot applied power in response, but the aircraft touched down with a scraping noise. The pilot noted that he did not recall seeing a green light indicating the gear was down and locked.
Investigation Findings
Post-incident inspection revealed that the circuit breaker for the landing gear motor was tripped. Additionally, the landing gear indication system was found to be inoperative due to a burned wire that resulted in an open circuit. The specific cause of the wire damage was not detailed in the investigation.
Pilot Account
The pilot reported that during the landing approach, he retarded the throttle, at which point the gear warning horn activated. Despite applying power, the aircraft made contact with the runway surface, producing a scraping sound. The pilot could not confirm seeing a green gear-down indication light.
Technical Details
The investigation confirmed two separate issues: a tripped circuit breaker affecting the landing gear motor, and an open circuit in the gear indication wiring caused by a burned wire. These factors prevented the landing gear from extending and the cockpit indication from functioning properly.
