## Discrepancy

RETURNED TO IAD DUE TO NR 2 GENERATOR PROBLEM.  AFTER EVENT, INITIAL IDG SERVICE AND ENGINE RUN PRODUCED NO FAULTS OR LEAKAGE, AND MONITORING AC REVEALED NO DUPLICATE EVENTS. INDICATION OF LOW OIL PRESSURE FROM INTERNAL CHARGE PRESSURE SWITCH CLOSURE MOST LIKELY DUE TO UNIT'S LOW OIL QUANTITY.
