## Discrepancy

AFTER INSTALLATION OF OVERHAULED STARTER/GENERATOR ON INITIAL START-OPERATIONAL CHECK, THE STARTER/GENERATOR DID NOT COME ON-LINE, IT WAS RESET WITH NO RESULTS.  IT WAS AGAIN RESET AND FUNCTIONED PROPERLY.  LATER, ACFT WAS DISPATCHED WITH NO DISCREPANCIES.  THE NEXT DAY, A MAINTENANCE RUN WAS PERFORMED TO VERIFY AN OIL SEEP ON THE TAIL GEARBOX.  ACFT STARTED NORMAL, BUT GENERATOR DID NOT COME ON-LINE.  AFTER SEVERAL ATTEMPTS TO RESET FAILED, STARTER/GENERATOR WAS REMOVED AND REPLACED.  SUBMITTER SUSPECTS INTERNAL FAILURE, INADEQUATE OVERHAUL, OR BENCH TESTING PROCEDURES.
