Airworthiness Directive · Amendment 39-21515 · Vacuum system
Piper Aircraft, Inc. Airplanes
This AD applies to the following Piper Aircraft, Inc., airplanes, certificated in any category:
(1) Model PA-46-350P (Malibu Mirage) airplanes, serial numbers (S/Ns) 4622041, 4636041, 4636142, 4636143, 4636313, 4636341, and 4636379;
(2) Model PA-46-500TP (Malibu Meridian) airplanes, S/Ns 4697141, 4697161, 4697086, and 4697020; and
(3) Models PA-46-350P (Malibu Mirage), PA-46R-350T (Malibu Matrix), and PA-46-500TP (Malibu Meridian) airplanes, all serial numbers, if the left wing has been replaced with a serviceable (more than zero hours time-in-service) wing.
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.
(1) Within 100 hours time-in-service (TIS) after the effective date of this AD or within 12 months after the effective date of this AD, whichever occurs first, inspect the configuration of the stall warning heat control system and, if required, install stall warning heat control modification kit part number (P/N) 88452-002 before further flight in accordance with steps 2 and 3 of the Instructions in Piper Aircraft, Inc., Service Letter No. 1261, dated July 19, 2019.
(2) As of the effective date of this AD, do not install a wing on any Model PA-46-350P (Malibu Mirage), PA-46R-350T (Malibu Matrix), or PA-46-500TP (Malibu Meridian) airplane unless you have determined that the wing has the correct stall warning heat control system as required by paragraph (g)(1) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
