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.

The pilot departed the slc international airport and headed to Ogden airport to practice ILS approach. While been vectored for an ILS landing the engine started to spudder. The pilot ajusted the mixture to correct the problem. That worked only temporarily but then it would start running rough again. It got worst so an emergency was declared and the pilot decided to land in a field. While he was manuvering for landing, the engine completely quite. The nose of the aircraft droped and he hit the ground hard on the three gear, bounced hit the ground a second time, bounced and then came to rest upside down. The nose gear was torn completely off, the engine was mostly torn loose, both wings received extensive damage and the top of the vertical stabilizer was crushed. The engine electrical and fuel systems were investigated for problems. The only item noticed that may have caused the failure of the engine was a loose b-nut on the fuel servo outlet hose. The fuel servo was sent to the manufacture for testing.
