## Discrepancy

PRE-TAKEOFF ENGINE RUNS COMPLETED, PILOTS TAXIED OUT ONTO ACTIVE, APPLIED TAKEOFF POWER, NR 1 ENGINE NO RESPONSE.  RETURNED TO LINE, AND SHUT DOWN.  MAINTENANCE INSPECTED AND FOUND TUBE ASSY CRACKED AT B-NUT FITTING AT REAR OF ENGINE.  THIS TUBE IS STAINLESS STEEL AND THE SLEEVE FOR THE B-NUT IS BRAZED ON TO THE TUBE, AND THE CRACK DEVELOPED AT THE END OF THE SLEEVE.  THIS TUBE FEEDS P3 AIR TO THE PROP GOVERNOR AND ITS FAILURE CAUSED A LOSS OF P3 AIR TO THE FUEL CONTROL PREVENTING IT FROM SPOOLING UP PAST IDLE REGARDLESS OF THROTTLE POSITION.
