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.

(.4) The pilot stated he was enroute to mid Florida airport, eustis, Florida, when a partial power loss and the inability to hold altitude necessitated a precautionary landing. The pilot said he executed a landing with a left quartering tailwind due to utility lines and trees blocking an approach into the wind. The aircraft bounced, and on the second bounce the right landing gear bent and the wind lifted the left wing. The aircraft slid, and slowly nosed over, coming to rest upside down, resulting in substantial damage to the aircraft. According to the pilot, the reason for engine power loss was due to insufficient torque on the jam nut exhaust valve adjuster (rocker arm) to number 4 cylinder.
