This AD was prompted by discovery during production that a section of vapor barrier seal was missing from the spar web cavities of the upper aft struts of both wings. We are issuing this AD to prevent flammable fluids from leaking onto parts of a hot exhaust system of a shut-down engine of an airplane on the ground, which could result in ignition of the flammable fluids and an uncontained fire. This could also lead to an emergency evacuation of the airplane and possible injury to passengers.
