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 unregistered homebuilt airplane experienced an engine failure, then began a left turn, which evolved into a cartwheel prior to impact. The engine's normal exhaust gas temperature range was 930 degrees to 1,150 degrees fahrenheit, while the maximum temperature was 1,200 degrees fahrenheit. The passenger remembered seeing a digital readout, as it passed through the number 1,168. Engine teardown revealed scuffing on the magneto piston, in the vicinity of the exhaust port, on the upper half of the piston skirt. Within the scuffing, carbon deposits were observed. Scuffing and carbon fill were also found at the 4 o'clock and 7 o'clock positions, relative to the exhaust port, also on the upper half of the piston skirt. The piston rings and cylinder walls exhibited scuffing as well, which positionally corresponded to the scuffing on the cylinder skirt. (-23)homebuilt a/c (SPRINT1000) departed the ultralight flight center in jackson township. The engine stalled and the pilot attempted to return to the airport. In the subsequent turn back, a/c apparently stalled hitted the ground. Pilot was fatally injured and expires on impact. The passenger is recovering from his injuries. The a/c was though to be an ultralight, but upon further investigation it was determined that the a/c was an unregistered airplane. No further action will take place-pilot deceased.

As the FAA filed it

(.4)THE UNREGISTERED HOMEBUILT AIRPLANE EXPERIENCED AN ENGINE FAILURE, THEN BEGAN A LEFT TURN, WHICH EVOLVED INTO A CARTWHEEL PRIOR TO IMPACT. THE ENGINE'S NORMAL EXHAUST GAS TEMPERATURE RANGE WAS 930 DEGREES TO 1,150 DEGREES FAHRENHEIT, WHILE THE MAXIMUM TEMPERATURE WAS 1,200 DEGREES FAHRENHEIT. THE PASSENGER REMEMBERED SEEING A DIGITAL READOUT, AS IT PASSED THROUGH THE NUMBER 1,168. ENGINE TEARDOWN REVEALED SCUFFING ON THE MAGNETO PISTON, IN THE VICINITY OF THE EXHAUST PORT, ON THE UPPER HALF OF THE PISTON SKIRT. WITHIN THE SCUFFING, CARBON DEPOSITS WERE OBSERVED. SCUFFING AND CARBON FILL WERE ALSO FOUND AT THE 4 O'CLOCK AND 7 O'CLOCK POSITIONS, RELATIVE TO THE EXHAUST PORT, ALSO ON THE UPPER HALF OF THE PISTON SKIRT. THE PISTON RINGS AND CYLINDER WALLS EXHIBITED SCUFFING AS WELL, WHICH POSITIONALLY CORRESPONDED TO THE SCUFFING ON THE CYLINDER SKIRT. (-23)HOMEBUILT A/C (SPRINT1000) DEPARTED THE ULTRALIGHT FLIGHT CENTER IN JACKSON TOWNSHIP. THE ENGINE STALLED AND THE PILOT ATTEMPTED TO RETURN TO THE AIRPORT. IN THE SUBSEQUENT TURN BACK, A/C APPARENTLY STALLED HITTED THE GROUND. PILOT WAS FATALLY INJURED AND EXPIRES ON IMPACT. THE PASSENGER IS RECOVERING FROM HIS INJURIES. THE A/C WAS THOUGH TO BE AN ULTRALIGHT, BUT UPON FURTHER INVESTIGATION IT WAS DETERMINED THAT THE A/C WAS AN UNREGISTERED AIRPLANE. NO FURTHER ACTION WILL TAKE PLACE-PILOT DECEASED.
