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 aircraft departed sus at 10:15 am on a pleasure flight. The aircraft lost engine power at 10:28 am and the pilot made an emergency landing on a road near Augusta MO. During the landing rollout the aircraft nose gear touched the ground and the aircraft flipped over on its back. (-23 amendment) further investigation found the engine super charger belt came off and went into the alternator drive belt. Both belts damaged the plastic timing belt cover allowing part of the belts to jam the timing belt drive gear to the cams; this altered the engine timing causing the engine to shut down. Probable cause was the super charger belt drive alignment.
