## Discrepancy

FIFTEEN MINUTES INTO THE FLIGHT,  THE NR 1 ENGINE EXPERIENCED A MOMENTARY POWER LOSS OF ABOUT TEN PERCENT TORQUE. ALL THE GAUGES INDICATED THE SAME AND THE ACFT YAWED IN THAT DIRECTION.  THIS LASTED ONLY A SECOND OR TWO, BUT A FEW MINUTES LATER THE SAME THING HAPPENED.  AT THIS POINT THE ACFT RETURNED TO BASE. ON THIS FLIGHT IT HAPPENED A TOTAL OF THREE TIMES.
