Requires repetitive inspections of the upper central fuselage II, III, and IV longitudinal splices. Prompted by a structural assessment indicating that certain central fuselage longitudinal splice fasteners are subject to fatigue damage that may reduce the structural residual strength below the required levels. This AD introduces maintenance tasks dedicated to identifying and correcting working fasteners to minimize the likelihood of failure in multiple fasteners that may jeopardize the airplane’s structural integrity.
