FAA Issues Airworthiness Directive for Boeing 747-100, 747-200B, and 747-200F Series Airplanes

Summary

The Federal Aviation Administration (FAA) has issued an airworthiness directive (AD) to modify and inspect certain Boeing 747-100, 747-200B, and 747-200F series airplanes to address fatigue cracking and corrosion in the fuselage upper lobe skin lap joints, which could lead to rapid decompression and structural failure. The new directive reduces the inspection interval and adds post-repair inspection requirements.
