BACKGROUND This service bulletin gives instructions to do inspections of Stringer 37 (S-37L and S-37R) lap splice just forward of the Body Station (STA) 434 circumferential splice for missing fasteners. Missing fasteners can result in cracks in the fuselage skin, which could adversely affect the structural integrity of the airplane.
Boeing has discovered that up to ten fasteners may not have been installed in Stringer 37 (S-37L and S-37R) lap splices on some airplanes during production. Accomplishment of the inspections and fastener installations, if necessary, in this service bulletin will help ensure the structural integrity of the S-37 lap splices.
Boeing Service Related Problem (SRP) 767-53-0424 and 767-53-0534 are related to this service bulletin.
