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.

Aircraft struck a tree during landing. (.4) the pilot reported that while in cruise flight, the engine RPM dropped and the airplane began to shake. The pilot checked the gauges, the throttle and mixture, the magnetos, fuel valve position, and found nothing wrong. The pilot stated that he notified air traffic of the loss of engine power, and diverted to a nearby airpark. The pilot entered the pattern and set-up for a short field landing, however, due to a tailwind, sloping terrain, and excess airspeed, the airplane floated a considerable distance down the runway. The pilot stated that when the airplane touched down, he realized that he did not have enough runway left to stop, and opted to turn off the runway onto a steep uphill taxiway. During the roll up this taxiway, the right wing struck trees and spun the airplane around 180 degrees. During the postcrash inspection of the engine, the exhaust valve for the number three cylinder was found broken.

As the FAA filed it

THE PILOT CHECKED THE GAUGES, THE THROTTLE AND MIXTURE, THE MAGNETOS, FUEL VALVE POSITION, AND FOUND NOTHING WRONG. THE PILOT STATED THAT HE NOTIFIED AIR TRAFFIC OF THE LOSS OF ENGINE POWER, AND DIVERTED TO A NEARBY AIRPARK. THE PILOT ENTERED THE PATTERN AND SET-UP FOR A SHORT FIELD LANDING, HOWEVER, DUE TO A TAILWIND, SLOPING TERRAIN, AND EXCESS AIRSPEED, THE AIRPLANE FLOATED A CONSIDERABLE DISTANCE DOWN THE RUNWAY. THE PILOT STATED THAT WHEN THE AIRPLANE TOUCHED DOWN, HE REALIZED THAT HE DID NOT HAVE ENOUGH RUNWAY LEFT TO STOP, AND OPTED TO TURN OFF THE RUNWAY ONTO A STEEP UPHILL TAXIWAY.
