## Discrepancy

(CAN) DURING PREFLIGHT WALK AROUND THE PILOT NOTICED THE RT ENG OTBD FIREWALL CONNECTOR, EVEN THOUGH LOCK WIRED SECURELY, WAS LOOSE.  FURTHER INSPECTION REVEALED THE LOCKING MECHANISM THAT HOLDS THE CONNECTOR THREADED COLLAR TO THE BODY OF THE CONNECTOR WAS DISLODGED.  THIS WOULD ENABLE THE FIREWALL CONNECTOR TO BE REMOVED, WITHOUT REMOVING THE LOCK WIRE.
