Incident Overview
According to the pilot, the aircraft had sufficient oil before departure and the flight was proceeding normally when the oil pressure suddenly dropped to zero. While diverting to a nearby airport, the engine lost power and seized, necessitating an off-airport emergency landing.
Post-Crash Examination
An FAA airworthiness inspector examined the engine after the accident. The inspection revealed that the oil plug was missing, and there was no evidence of safety wiring. The aircraft had just been released from maintenance, according to the inspector.
Aircraft and Maintenance
The specific aircraft type, registration, and operator were not detailed in the source. The aircraft had recently undergone maintenance, as stated by the inspector. No other mechanical issues were mentioned.
Occupants and Injuries
The source does not provide information on the number of occupants or any injuries sustained. Accordingly, no such details are included in this report.
Conclusion
The facts as reported indicate that the loss of oil pressure and subsequent engine failure were associated with the missing oil plug and lack of safety wiring. However, the investigation does not explicitly assign a probable cause.
