Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 757-200, -200PF, and -200CB series airplanes. This proposed AD would require inspections to detect scribe lines and cracks of the fuselage skin, lap joints, circumferential butt splice strap, and external and internal approved repairs; and related investigative/corrective actions if necessary. This proposed AD results from reports of scribe lines adjacent to the skin lap joints. We are proposing this AD to detect and correct cracks, which could grow and cause rapid decompression of the airplane.
