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) On 06-11-2001, at 0158Z, N3847U operated by (PIC) privacy data omitted with privacy data omitted as passenger, landed at crp with one engine shut down and prop feathered due to loss of engine oil press. The pilot feathered the prop after noting low oil pressure and contacted crp ATC for landing instructions. The aircraft landed at crp without further incident. The pilot stated that no fires or injuries occurred as a result of this incident. The aircraft was towed to advantage aircraft services (FBO) for maintenance. Brief explanation of issues involved: through further investigation it was noted that the prop oil press line had chafed the engine cowl on the forward engine and depleted the oil system thus causing the engine to seize. A statement from the mechanic, privacy data omitted, identified that the oil pressure hose from the prop governor chafed with a fastener on the engine cowl. The chafing hose was undetectable by the PIC during a preflight inspection. The engine would turn over, however, some internal interference with the piston would not allow it to run. One piston was seized in place. Approximately 20 flight hours prior to this flight, this aircraft had an annu al inspection performed and no discrepancies with the prop governor hose were noted. This is a no fault isolated incident and this office considers this matter closed.
