JUST AFTER TAKEOFF, THE ENGINE EXPERIENCED A POWER LOSS WHILE TRANSPORTING AGRICULTURAL EQUIPMENT. A FRACTOGRAPHIC EXAMINATION OF THE FAILED FUEL DISCONNECT FITTING BY ANAMET LABORATORIES, CONCLUDED THAT APPROXIMATELY 70% OF THE RETAINING RING ON THE FUEL DISCONNECT FITTING HAD FRACTURED BY METAL FATIGUE. THE FATIGUE CRACK WAS PRESENT PRIOR TO THE CRASH; HOWEVER, IT COULD NOT BE DETERMINED WHETHER THE FRACTURE MAY HAVE CAUSED PARTIAL CLOSING OF THE DISCONNECT VALVE IN THE FITTING. THIS COULD CUT OFF THE FUEL SUPPLY DURING OPERATION.
