## Discrepancy

BEARING WAS PURCHASED AS PMA PART FROM SUPERIOR TURBINE.  AN INFORMATION LETTER FROM SUPERIOR DATED MAY 1, 1995, RECOMMENDED INSPECTION OF BEARING AND FILTER FOR METAL FLAKES.  THIRTEEN PIECES FOUND IN FILTER, ONE WAS 'TRIANGULAR 2 X 4MM', SINCE TWO SB HAVE BEEN ISSUED FROM SUPERIOR, ONE FOR NR 5 AND ONE FOR NR 8 BEARINGS.
