What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2021-04-07 which applied to certain Piper Aircraft, Inc., (Piper) Models PA-46- 350P (Malibu Mirage), PA-46R-350T (Malibu Matrix), and PA-46-500TP (Malibu Meridian) airplanes. AD 2021-04-07 required identifying and correcting nonconforming stall warning heat control systems. Since AD 2021-04-07 was issued, the FAA was notified of an error in the stall warning heat control modification kit part number. This AD retains all of the actions in AD 2021-04-07 and corrects the incorrect modification kit part number. The FAA is issuing this AD to address the unsafe condition on these products.

Whether AD 2021-09-02 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 2021-09-02 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.
