Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to Brackett Aircraft Company (Brackett) single screen air filter assemblies that are installed on airplanes. This proposed AD would require you to check the Brackett single screen air filter assembly for correct installation. This proposed AD would also require you to install an additional screen, replace the Brackett single screen air filter assembly with a double screen filter, or replace with another approved design filter at a specified time. This proposed AD is the result of several reports of service difficulties of incorrect installation of the air filters. The actions specified by this proposed AD are intended to detect and correct incorrect installation of the air filter, which could result in failure of the air filter. Such failure could lead to engine/turbocharger ingestion of the air filter foam element.
