## Discrepancy

DURING DESCENT OUT OF 16,000, CREW NOTICED UNUSUAL ENGINE INDICATIONS.  CREW COMPLIED WITH RELEVANT CHECKLISTS AND LANDED AT BDL WITHOUT FURTHER INCIDENT.  MAINTENANCE HAS DISPATCHED CONTRACT MECHANIC TO EXAMINE THE PROBLEM.  BORESCOPED ENGINE, NO DAMAGE FOUND, CHANGED THE ANTI-ICE START VALVE AND PERFORMED ENGINE RUNS, OPS CHECKED GOOD.
