## Discrepancy

(CAN) AFTER ENGINE REPLACED, POWER CHECK WAS CARRIED OUT WHERE ENGINE WOULD PRODUCE ONLY 80 PERCENT TORQUE.  INVESTIGATION REVEALED A CRACK IN THE 6 CUBIC INCH ACCUMULATOR IN THE PY LINE.  THE CRACK WAS FOUND IN THE AREA WHERE THE END FITTING FOR THE PY LINE IS WELDED TO THE END OF THE ACCUMULATOR.  THE NEW REPLACEMENT ACCUMULATOR HAD A DOUBLER AT THIS AREA.
