## Discrepancy

DURING GROUND RUN, FUEL PRESSURE OUTPUT FROM THE LEFT ENGINE WAS BELOW NORMAL, AND WOULD FLUCTUATE AT LOWER IDLE SPEEDS.  THE FUEL SERVO SCREEN WAS CHECKED DURING THE INSPECTION AND BITS OF METAL WERE FOUND.  THE PUMP WAS REMOVED AND WHEN THE DRIVE SPLINE WAS ROTATED BY HAND A RESISTANCE TO ROTATION WAS FELT AT A CERTAIN POINT.
