## Discrepancy

DURING TESTING OF ENGINE P-44720 AFTER REPAIR DUE TO BIRD INGESTION, IT WAS NOTED THAT THE NTS SYSTEM WOULD NOT SET IAW MM 72-00-25 REV 13, DATED FEB. 13 2003.  AFTER TROUBLESHOOTING, HAD FOUND THAT THE NTS VALVE WOULD NOT SET (STUCK CLOSED) CAUSING THE NTS SYS TO FAIL.  REPLACED THE VALVE WITH A NEW VALVE PN 70100012-1, SN 08P23169, NTS SYS TESTED GOOD.
