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) On downwind, during takeoff the pilot encountered extreme vibration coming from the engine. The pilot shut down the engine and the vibration ceased. The pilot was able to glide to the runway and make an uneventful landing. The cause of the vibration was the loss of one propeller blade that had separated from the hub. The damage to the aircraft was substantial as the engine mount area of the firewall was damaged on this composite type motor glider.
