## Discrepancy

DURING HOVER ON A LONG-LINE OPERATION, THE ENGINE CHIP LIGHT ILLUMINATED.  PRECAUTIONARY LANDING PERFORMED AND GRAINS OF METAL WERE FOUND ON THE RT UPPER ENGINE CHIP DETECTOR.  FOUND TO BE THE NR 1 BEARING IN THE COMPRESSOR.  THIS IS THE OLD, ORIGINAL PART THAT WE ARE REPLACING WITH AN UPGRADED FRONT HOUSING AND BEARING IAW SB 72-3242.  SOME INFO IS MISSING AS THE ENGINE AND ITS LOGS WERE SENT OFF FOR REPAIR BEFORE THIS REPORT WAS GENERATED.
