FAA Issues Updated Airworthiness Directive for Boeing 747-200C, -200F, -400, -400D, and -400F Series Airplanes

The Federal Aviation Administration (FAA) is issuing an updated airworthiness directive (AD) for certain Boeing 747-200C, -200F, -400, -400D, and -400F series airplanes to address fatigue cracking in lap joints, which could lead to rapid depressurization of the aircraft. The new directive expands the inspection area and adds post-repair inspections to prevent such incidents.
