## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Piper Aircraft, Inc. (Piper) Model PA-28-140, PA-28-150, PA-28-160, PA-28-180, PA-28S-160, PA-28S-180, PA-28-236, PA-28-201T, PA-32-300, PA-32R-300, PA-32RT-300, PA-32RT-300T, PA-32-301FT, PA-32- 301XTC, PA-32R-301 (HP), PA-32R-301 (SP), PA-32R-301T, PA-32-301, and PA-32-301T airplanes. This proposed AD was prompted by a report of a wing separation caused by fatigue cracking in a visually inaccessible area of the lower main wing spar cap and additional reports of fatigue cracking in the wing spars of airplanes that share common type design features. This proposed AD would require reviewing airplane maintenance records to determine if an eddy current inspection of the lower main wing spar bolt holes was done and, depending on the result, doing a one-time eddy current inspection of the lower wing spar bolt holes for crack(s), and replacing any cracked main wing spar. The FAA is proposing this AD to address the unsafe condition on these products.
