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) The initial presumption was that a bird strike caused left inboard flap to go into asymmetrical position. Maintenance changed out flap drive mechanism. Substantiation of bird strike through photos. Damage to aircraft or physical remains could not be provided. Cycling of flaps by maintenance did not validate asymmetrical condition existed. Maintenance could not positively duplicate in-flight condition. Removed and replaced part on aircraft as a precautionary measure. What caused condition in flight to occur is still conjecture.
