## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. (Piper) Model PA-46-600TP (M600) airplanes. This AD requires inserting a ground operations limitation into the Limitations section of the airplane flight manual (AFM) and installing a placard limiting ground operations. This AD also includes optional actions to terminate the ground operating limitations. This AD was prompted by a report of understrength rivets installed during manufacture of the bulkhead assembly. The FAA is issuing this AD to address the unsafe condition on these products.
