From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) Purpose of flight was a maintenance test flight. Pilot and passenger reported actuating landing gear, hearing a muffled pop and seeing the nose wheel and left hand main wheel indicator lamps indicate green;right hand gear lamp indicated unsafe. Both aircraft occupants reported that the gear motor circuit breaker opened. Pilot reset circuit breaker and reported seeing circuit breaker open again. Pilot initiated emergency procedures and had passenger mechanic attempt lowering gear manually using the emergency hand crank. The emergency gear extension also failed. Witnesses on the ground reported seeing the right hand main landing gear fully retracted with its gear door closed. The other landing gear wheels were observed fully extended. The passenger reported pulling up the aircraft floor board inspection panels and observing the right hand main gear retract rod assembly connector linkage between the landing gear box and right hand retract rod assembly bowed up and bent. Pilot was able to electrically retract the remaining landing gear wheels and perform a safe gear up landing.
