## Discrepancy

DURING A MAINTENANCE CHECK FLIGHT, THE ENGINE EMITTED A LOUND NOISE ACCOMPANIED BY AN UNCOMMANDED POWER REDUCTION.  THE ENGINE WAS SHUT DOWN IN FLIGHT.  SUBSEQUENT INSPECTION REVEALED DAMAGE TO THE COMPRESSOR AND INLET AREA.  P&WC WILL INVESTIGATE THE EVENT AND ADVISE OF ROOT CAUSE ONCE ESTABLISHED.
