## Discrepancy

DURING AN ANNUAL INSPECTION, THE AIR FILTER WAS DISCOVERED TO BE SPLIT OPEN AT THE SEAM.  THIS SAME CONDITION HAS BEEN FOUND ON SEVERAL OTHER AIR FILTERS OF THE SAME PN.  WHILE NOT AN IMMEDIATE SAFTEY OF FLIGHT ISSUE, THIS CONDITION ALLOWS UNFILTERED AIR TO ENTER THE INDUCTION SYSTEM WHICH IF ALLOWED TO CONTINUE FOR ANY GREAT LENGTH OF TIME CAN CAUSE PREMATURE WEAR AND POSSIBLE EARLY FAILURE OF THE ENGINE.
