Fasteners May Be Missing, Which Could Lead To Skin Cracks

The FAA has proposed an AD for certain Boeing model 767 airplanes. This proposed AD was prompted by reports that six fasteners may not have been installed in the left and right stringer 37 (S-37) between body station (BS) 428 and 431 lap splices on certain airplanes.

This proposed AD would require a general visual inspection of S-37 lap splices for missing fasteners; and all applicable related investigative and corrective actions.

The FAA is proposing this AD to detect and correct missing fasteners, which could result in cracks in the fuselage skin that could adversely affect the structural integrity of the airplane.

The agency has received reports that six fasteners may not have been installed in the left and right stringer 37 (S-37) between BS 428 and 431 lap splices on certain airplanes during production. This condition, if not corrected, could result in cracks in the fuselage skin that could adversely affect the structural integrity of the airplane.

The proposed AD is open for comments until February 12, 2015.
