Airworthiness Directive · Amendment 39-18980 · Wing spar
Piper Aircraft, Inc. Airplanes
This AD applies to Piper Aircraft, Inc. Model PA-46-600TP (M600) airplanes; serial numbers 4698004 through 4698042; certificated in any category.
We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. (Piper) Model PA-46-600TP (M600) airplanes. This AD requires inspection of the aft wing spars with repair as necessary. This AD was prompted by a report from Piper of the aft wing spar cracking during wing assembly. We are issuing this AD to address the unsafe condition on these products.
Before further flight, inspect the aft wing spars and, before further flight, repair as necessary following FAA-approved procedures obtained from the Atlanta ACO Branch approved specifically for this AD. Use the contact information found in paragraph (j) of this AD. We are coordinating with Piper on the development of inspection and repair procedures to address this unsafe condition. Piper Aircraft, Inc. Service Bulletin No. 1317, dated July 21, 2017 (not incorporated by reference), and Piper Service Bulletin No. 1317A, dated July 26, 2017, contain additional information related to 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.
