## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain The New Piper Aircraft, Inc. (Piper) J-2 series airplanes equipped with wing lift struts. The proposed AD would require repetitively inspecting the wing lift struts for dents and corrosion and the wing lift strut forks for cracks; replacing any strut found with corrosion or dents, or forks with cracks; and repetitively replacing the wing lift strut forks. The proposed AD would also require incorporating a ``NO STEP'' placard on the lift strut. The proposed AD is the result of the Federal Aviation Administration (FAA) inadvertently omitting the J-2 series airplanes from the applicability of AD 99-01-05. The actions specified by the proposed AD are intended to prevent in-flight separation of the wing from the airplane caused by wing lift struts with dents or corrosion or wing lift forks with cracks, which could result in loss of control of the airplane.
