Primary finding
Probable cause
The pilot's failure to ensure the landing gear was extended into the fully locked position.
Investigator assessment
Analysis narrative
The pilot reported he experienced an electrical failure while enroute to his destination. As he approached the airport and lowered the landing gear switch handle, he heard the landing gear lower and felt the airplane slow down. He received the normal indications the landing gear was down and visually confirmed it using the mirror on the left wing. The pilot reported he used the manual crank to ensure the gear was in the locked position. As the airplane touched down, the right landing gear and nose gear collapsed. The airplane sustained substantial damage to the right wing. A FAA inspector's examination of the airplane's electrical system showed system reliability.
