## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to de Havilland DHC-6 series airplanes that do not have a certain wing strut modification (Modification 6/1581) incorporated. The proposed action would require inspecting the wing struts for cracks or damage (chafing, etc.), replacing wings struts that are found damaged beyond certain limits or are found cracked, and incorporating Modification No. 6/1581 to prevent future chafing damage. Several reports of wing strut damage caused by the upper fairing rubbing against the wing strut prompted the proposed action. The actions specified by the proposed AD are intended to prevent failure of the wing struts, which could result in loss of control of the airplane.
