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) Aircraft experienced a faulty gear indication during final. The left main landing gear indicator did not turn green indicating the gear was down and locked. The pilot followed emergency procedures and cycled the gear to no avail. He attempted to blow the gear down with negative results. Upon landing, the left main landing gear collapsed. There were drag marks from that point all the way to the grassy area, where the aircraft came to rest. During lifting of the aircraft, the left main landing gear began to extend on its own and stopped approximately 7/8THS from full extension. Cape air maintenance pulled the gear, without much effort; until a firm click was heard indicating the gear was down and locked. Inspectors inspected the left main landing gear actuator and there were no leaking, broken, or kinked hydraulic lines, and the hydraulic reservoir was full. The nitrogen bottle used to blow the gear down, still had 400 pounds per square inch in it. Inspectors asked cape air maintenance to turn power on the aircraft, so they could note gear indications, and all three gears showed green indicating they were all down and locked.
