## Discrepancy

FOR APPROX A MONTH, NOTICED EITHER DURING ANNUAL INSP OR OIL CHANGES, THAT SEVERAL BA-24 AIR FILTERS HAVE FAILED. IT APPEARS THAT THE ADHESIVE USED ON THE SEAM IS FAILING AND THE FILTER SEPARATES ALLOWING UNFILTERED AIR TO ENTER THE INDUCTION SYS.  WE ARE A BUSY SERVICE CENTER AND MAINTAIN NUMEROUS ACFT. I WISH THERE WAS A WAY TO ASCERTAIN THE BATCH NR OF THE AFFECTED FILTER ELEMENTS, BUT THAT IS NOT POSSIBLE AS AIR FILTER BATCH NR INFO IS NOT PART OF A NORMAL LOG ENTRY.  WE ARE NOT THE ONLY SHOP EXPERIENCING THIS AND APPRECIATE YOUR HELP FOR A RESOLUTION.
