What happened
As the pilot approached the destination airport, the landing gear selector was placed in the down position. Initially, the landing gear failed to extend. The pilot then reset the circuit breaker for the electric gear motor, after which the gear did extend. The pilot reported observing the green position light illuminate and believed the gear was locked in the down position.
The aircraft made a normal touchdown; however, seconds after contact with the runway, the landing gear collapsed. There were no injuries reported in this incident.
The investigation
An examination of the landing gear extension system was conducted. Investigators found that the system functioned properly when manually extended. Due to damage sustained during the impact, the gear system could not be electrically operated during the post-accident examination.
