## Discrepancy

DURING A MFG 1000 HR INSPECTION, THE EMERGENCY FUEL SHUTOFF ARM WAS REMOVED TO INSPECT A VALVE KNOWN TO LOOSEN UP AND PRODUCE LEAKS.  THE JAM NUT WAS LESS THAN FINGER TIGHT.  THERE WAS NO LOCTITE OR SELF-LOCKING MECHANISM APPARENTLY BY DESIGN.  THE NUT WAS REMOVED, SHAFT CLEANED, AND REASSEMBLED WITH LOCTITE BLUE.
