NTSB Probable Cause

THE FAILURE OF THE NUMBER ONE CYLINDER FUEL INJECTOR LINE DUE TO FATIGUE CRACKING INDUCED BY CORROSION AND PROPAGATED BY CYCLIC LOADING WHICH RESULTED IN A TOTAL LOSS OF ENGINE POWER. THE CORROSION WAS DUE TO THE MANUFACTURER'S PROCESS OF BRAZING THE METAL JOINT, AND THE CYCLIC LOADING WAS DUE TO THE ABSENCE OF A CLAMP TO MINIMIZE THE EFFECT OF VIBRATION. A CONTIBUTING FACTOR WAS THE LACK OF SUITABLE TERRAIN DURING THE SUBSEQUENT FORCED LANDING.
