Airworthiness Directive · Amendment 39-22060 · Wing spar
Piper Aircraft, Inc. Airplanes
This AD applies to Piper Aircraft, Inc. Model PA-46-600TP airplanes, serial numbers 4698001, 4698004 through 4698146 inclusive, 4698148, and 4698150 through 4698157 inclusive, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. (Piper) Model PA-46-600TP airplanes. This AD was prompted by testing that showed that the wing splice assembly could fail before the assembly reaches its established life limit. This AD requires revising the Airworthiness Limitations section (ALS) of the existing maintenance manual (MM) or instructions for continued airworthiness (ICA) to reduce the life limit of the wing splice assembly. The FAA is issuing this AD to address the unsafe condition on these products.
Within 90 days after the effective date of this AD, revise the Airworthiness Limitations section in the existing maintenance manual or instructions for continued airworthiness by reducing the life limit of the wing splice assembly part number 46W57A100-001 to 3,767 hours time-in-service.
Note 1 to paragraph (g): Section 4-00-00 of Piper Aircraft, Inc. PA-46-600TP, M600 Maintenance Manual, Airworthiness Limitations, Page 1, dated August 31, 2021, contains the life limit in paragraph (g) 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.
