## Discrepancy

DURING AN ANNUAL INSPECTION, THE ENGINE OIL SUCTION SCREEN WAS FOUND TO CONTAIN A SPRING AND FRAGMENTS OF A RUBBER COMPOUND.  TELEDYNE CONTINENTAL SB CSB 95-4 PERTAINS TO THIS SUBJECT, BUT IS NOT SUBJECT TO MODELS AFFECTED BY SERIAL NUMBER.  THE SB WAS C/W ON BOTH ENGINES, AND EACH SEAL WAS FOUND DEFECTIVE IN EACH ENGINE.  SUGGEST REVISING SERIAL NUMBER APPLICABILITY OF SB.
