## Discrepancy

DURING CRUISE PHASE OF FLIGHT, THE RT ENG EXPERIENCED LOSS OF FUEL PRESS.  PILOT SHUT THE RT ENG DOWN, CONTACTED ATC & WAS DIVERTED.  TECHNICIANS INSPECTED THE ENG & FOUND THE CAP HAD SEPARATED FROM THE HIGH PRESS RELIEF VLV, WHICH RESULTED IN THE LOSS OF FUEL PRESS.  ONCE THE FUEL PUMP COULD BE REMOVED, THE HIGH PRESS RELIEF VLV WAS DISASSEMBLED FOR FURTHER EXAMINATION.  A FRACTURE IN THE THREADS OF THE RELIEF VLV BODY AT THE CAP END WAS DISCOVERED.  A BENCH TEST OF THE FUEL PUMP, WITH A DIFFERENT RELIEF VLV INSTALLED, WILL BE CONDUCTED TO DETERMINE IF THE PUMP WAS AT FAULT.  ALSO, FURTHER STUDY OF THE RELIEF VLV ASSEMBLY WILL BE CONDUCTED.
