## Discrepancy

DURING COMPLETION OF AD 78-09-07 ON LT ENGINE AND WHILE INSTALLING LT MAG, RUBBER DRIVE COUPLING WAS DROPPED INTO ENGINE.  WHEN SUMP DRAIN WAS REMOVED TO RETRIEVE COUPLING, TWO WERE FOUND NEAR THE QUICK DRAIN.  ENGINE HAD A HISTORY OF LOW OIL PRESSURE ON OCCASIONS, BUT REASON HAD NOT BEEN FOUND.  IT IS BELIEVED THE PREVIOUSLY LOST COUPLING WAS REASON FOR LOW OIL PRESSURES.
