Part-conditional — 638873, 460-632, PS60007-2.

Applies to airplanes with a Purolator/Facet induction air filter installed, Purolator P/N 638873, Model No. CA161PL (Piper P/N 460-632 / PS60007-2), manufactured January 1997 through September 1998 and identified with a 0.250-inch ink stamp 'FACET-638873' (may include 'FAA-PMA'), installed on the airplane between January 1, 1997 and January 13, 2000. Prevents pieces of a damaged induction air filter from being ingested into the engine, causing reduced or loss of engine power; requires replacement with an FAA-approved filter within 25 hours TIS.

Whether AD 99-26-05 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 99-26-05 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
