Airworthiness Directive · Amendment 39-10747 · Boeing Model 757-200 Series Airplanes
Boeing Model 757-200 Series Airplanes
Model 757-200 series airplanes, line numbers 1 through 724 inclusive, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 757-200 series airplanes, that requires the application of a sealant, secondary fuel barrier, and corrosion-inhibiting compound to certain portions of the wing center section. This amendment is prompted by reports indicating that, during manufacture, the secondary fuel barrier was not applied to certain portions of the wing center section. The actions specified by this AD are intended to prevent leakage of fuel through the fasteners, sealant, or structural cracks in the center section structure, which could result in fuel or fuel vapors entering the cargo or passenger compartment of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
