## Discrepancy

AIRCRAFT IN CRUISE, ENGINE SPUTTERED AND DIED.  BOOST PUMP ACTIVATED AND ENGINE RESTARTED.  PART IS AN ON-CONDITION ITEM.  THE SQUARE DRIVE ROUNDED OFF UNTIL IT WOULD NO LONGER ENGAGE THE DRIVE GEAR P/N 631684.  THIS CAUSED THE FUEL PUMP TO STOP ROTATING RESULTING IN ENGINE STOPPAGE.
