## Discrepancy

PART OF THE GASKET OF THE INLET SCREEN CAME LOOSE AND WAS INGESTED INTO THE ENGINE.  ONE BLADE ON THE COMPRESSOR HAD DAMAGE THAT CAUSED A LOUD WHINING NOISE WHEN THE ENGINE WAS OPERATED.  THE ONLY DAMAGE THAT CAN BE OBSERVED IS THE COMPRESSOR BLADES.  IT IS BELIEVED THAT THE POSSIBLY OF OVER TORQUING THE INLET SCREEN MAY HAVE CONTRIBUTED TO THE GASKET FAILURE ALONG WITH NOT ENOUGH ADHESIVE ON THE GASKET TO ENSURE IT WOULD NOT RELEASE.
