AD 99-05-09 64 FR 10211

This amendment adopts a new airworthiness directive (AD) that applies to certain The New Piper Aircraft, Inc. (Piper) PA-23, PA-24, PA-28, PA-32, and PA-34 series airplanes that incorporate certain Facet (manufactured by the Purolator Products Company) induction air filters. This AD requires replacing these induction air filters. This AD results from reports of cracking, splitting, crumbling, and deterioration (referred to as damage hereon) of Facet/Purolator induction air filters manufactured between a certain time period. The actions specified by this AD are intended to prevent pieces of a damaged induction air filter from being ingested into the engine, which could result in reduced or loss of engine power.
