## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain The New Piper Aircraft, Inc. (Piper) Model PA-46-350P airplanes. The proposed AD would require installing reinforcement plates to the wing forward and aft attach fittings. The proposed AD is the result of a report that sheet steel material that is below design strength standards could be utilized on the wing attach fittings on the Model PA-46-350P airplanes manufactured since January 1995. The actions specified by the proposed AD are intended to prevent structural failure of the wing attach fittings caused by the utilization of substandard material, which could result in the wing separating from the airplane with consequent loss of control.
