Full official abstract

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