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.

A landing was conducted on runway 05 at klwm. After the landing gear was lowered the pilot reported 1) seeing the green landing gear light illuminated, 2) the touchdown on the main gear was smooth; 3) shortly after touchdown the nose and right main gear collapsed, followed by the left main gear, 4) two passengers were on board, one passenger in the right front seat and another passenger, a 26 year old autistic female, in a rear seat. The aircraft left the pavement on the right side of the runway. After stopping the pilot and passengers evacuated the aircraft. There were no injuries.

Post incident inspection revealed a headset cord tightly wrapped around the un-stowed landing gear hand crank handle. The landing gear circuit breaker was popped out. During a further interview the pilot reported 1) the preflight inspection did not reveal any discrepancies, 2) the aircraft pilot operating handbook (POH) checklist was completed prior to engine start. Some items were added that are not included in the checklist, I.e. manual gear handle stowed, 3) the landing gear hand crank handle was stowed, but there never was a hand crank handle cover available in the aircraft, 4) if the landing gear hand crank handle is not stowed, it will rotate rapidly when the landing gear is lowered electrically, 5) the passenger in the rear seat was wearing a headset and thoroughly briefed on its use, 6) the mechanical landing gear position indicator pointed to down (post incident inspection revealed the mechanical landing gear position indicator only indicated approximately 2/3 down), 7) the headset cord wrapped around the hand crank handle belonged to the passenger in the rear seat.
