## Discrepancy

UPON RECEIVING FROM ALLISON (NEW) 3-8-96, NOZZLE HAD A DIAPHRAGM MOVEMENT OF .004 INCH.  ACCORDING TO CEB-72-3188, THE DIAPHRAGM SHOULD HAVE A MAXIMUM MOVEMENT OF .003 INCH.  THIS IS UNACCEPTABLE.  THE NOZZLE WAS SENT BACK TO ALLISON FOR WARRANTY.  TIGHTENED THE KEYS ON THE DIAPHRAGM INNER RING.
