What to do
Operators of affected Piper PA-46-350P, PA-46R-350T, and PA-46-500TP airplanes must inspect the stall warning heat control system configuration and correct any nonconformities using the correct modification kit P/N 88452-002. The AD is effective April 16, 2021, and comments are invited until June 1, 2021. Compliance with the inspection and any necessary repairs should be prioritized to mitigate safety risks.
Summary
Airworthiness Directive 2021-09-02 is a final rule issued by the Federal Aviation Administration addressing certain Piper Aircraft, Inc. models PA-46-350P (Malibu Mirage), PA-46R-350T (Malibu Matrix), and PA-46-500TP (Malibu Meridian) airplanes. This directive corrects an error in the previously issued AD 2021-04-07 regarding the part number of the stall warning heat control modification kit. It requires inspection and correction of nonconforming stall warning heat control systems to ensure compliance with the proper design.
What changed
This AD supersedes AD 2021-04-07 by retaining all its requirements but correcting the stall warning heat control modification kit part number from P/N 8452-002 to the correct P/N 88452-002. The correction addresses an error that made compliance with the previous AD impossible. Additionally, this AD removes the requirement to review aircraft records before inspection, mandating inspection for all affected airplanes.
Why it matters
This directive is critical for aviation professionals because it ensures the proper functioning of the stall warning heat control system, which is essential for flight safety during icing conditions. Failure to comply could result in undetected stall warnings, increasing the risk of accidents. Operators, maintenance organizations, and compliance teams must address this to maintain airworthiness and regulatory compliance.
