## Discrepancy

(CAN) DURING A MX ACTION IT WAS NOTED THAT LOCKWIRE ON TOP OF TORQUE LIMITER WAS LOOSE.  THIS LOCKWIRE LOCKS 2 SCREWS WHICH HOLD OIL FITTING AND LINE THAT ATTACHES TO TORQUE TRANSDUCER.  LOCKWIRE WAS REMOVED AND ONE SCREW WAS FOUND STRIPPED INTERNALLY.  A SERIUOS OIL LEAK WAS AVOIDED.  SCREW AND LOCK WIRE ARE INSTALLED AT O/H FACILITY.  INSP OF COMPANY ACFT IS UNDERWAY FOR ANY OTHER SIMILAR FAULTS. IT APPEARS 1 SCREW WAS INSTALLED AND TIGHTENED AND THEN SECOND SCREW INSTALLED AT AN ANGLE AND TIGHTENED AND LOCKWIRED.  TORQUE LIMITER HAS BEEN SENT FOR O/H AND A REQUEST FOR A TEARDOWN REPORT HAS BEEN MADE.
