Analysis

THE PILOT STATED THAT THE AIRCRAFT HAD PLENTY OF OIL PRIOR TO DEPARTURE AND THAT THE FLIGHT WAS PROCEEDING NORMALLY WHEN, SUDDENLY, THE OIL PRESSURE DROPPED TO ZERO. WHILE SUBSEQUENTLY HEADING FOR A NEARBY AIRPORT, THE ENGINE LOST POWER AND SEIZED, FORCING AN OFF-AIRPORT EMERGENCY LANDING, ACCORDING TO THE PILOT. A POST-CRASH EXAMINATION OF THE ENGINE BY AN FAA AIRWORTHINESS INSPECTOR 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.
