## Discrepancy

CREW ABORTED TAKEOFF AT 135 KNOTS DUE TO LEFT ENGINE FIRE WARNING.  *S/D*  ONE FUEL TRANSFER TUBE B-NUT FOUND LOOSE.  THE NUT AND O-RING WERE REINSTALLED, SEATED BY HAND AND THEN RETORQUED.  THE  SYSTEM WAS PRESSURIZED AND RUN AT IDLE POWER, WITH NO LEAKS NOTED.  THE FAILURE WAS A RESULT OF A DAMAGED O-RING SEAL ON THE FUEL TRANSFER TUBE BETWEEN THE MANIFOLD AND FUEL NOZZLE.
