Airworthiness Directive 99-05-09
one-timeAirworthiness Directives; The New Piper Aircraft, Inc. PA-23, PA- 24, PA-28, PA-32, and PA-34 Series Airplanes
What this AD requires
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.
Which aircraft AD 99-05-09 applies to
Applies only if a Purolator/Facet induction air filter (Purolator P/N 638873, Model No. CA161PL; also supplied under Piper P/N 460-632 (PS60007-2)) manufactured January 1997 through September 1998 and marked with a 1/4-inch 'FACET-638873' ink stamp is installed; if not installed, the AD does not apply. Requires replacement with an FAA-approved induction air filter, to prevent pieces of a damaged filter from being ingested into the engine and causing reduced or loss of engine power. Installed on Piper airplanes per the referenced Piper part number.
Whether AD 99-05-09 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
