## Discrepancy

AIRCRAFT WAS FLYING FROM TULSA TO SILOAM SPRINGS, 8 MILES FROM SILOAM SPRINGS AIRPORT, PILOT REPORTED THE ENGINE OIL PRESSURE WAS FLUCTUATING FROM ZERO TO 60 PSI.  THE ENGINE THEN STARTED TO VIBRATE SEVERELY BEFORE THE ENGINE COMPLETELY STOPPED.  UPON INSPECTION OF THE AIRCRAFT, FOUND THE OIL QUICK DRAIN WAS MISSING WHICH OBVIOUSLY CAUSED THE ENGINE TO LOSE OIL PRESSURE.  THE QUICK DRAIN INSTALLED DID NOT HAVE A PROVISION FOR SAFETY WIRE.
