## Discrepancy

PREMATURE ENGINE OVERHAUL MAY HAVE BEEN A RESULT OF WORN FILTER SUPPORT RINGS.  EDGES OF RING FLANGES WERE ABOUT 50 PERCENT MISSING.  THE ALUMINUM PIECES PRESUMABLY WERE INGESTED INTO ENGINES.  THESE RINGS WERE NOT REPLACED AT O/H IN 1992, BUT BOTH REPLACED AT 1995 ANNUAL.  HOW MUCH OF THE FLANGES HAVE BEEN INGESTED SINCE 1992 IS UNKNOWN.
