What happened
The pilot reported that he had completed a normal landing. After touchdown, he intended to retract the flaps but inadvertently retracted the landing gear instead. Despite this error, there were indications that the landing gear was not fully extended during the touchdown phase of the event.
The investigation
Investigators examined the aircraft's systems following the incident. They discovered that the landing gear circuit breaker had popped out of its socket. To rule out mechanical failure or sensor issues, the team checked the landing gear safety switch and confirmed it operated properly. Additionally, the gear warning horn was tested and found to operate normally.
Findings
The primary contributing factor was the pilot's action of retracting the gear instead of the flaps after a normal landing. The investigation also identified that the landing gear circuit breaker had tripped or popped, which may have affected system status indicators or functionality during the event.
