Plain English Summary

2/10 complexity

What this is: A mandatory safety notice (Airworthiness Directive) requiring airlines and aircraft owners to inspect specific Boeing 747 aircraft for dangerous cracks in the fuselage (the main body of the plane).

Who it affects: Owners and operators of Boeing 747-200F, -200C, -400, -400D, and -400F series aircraft.

What must be done: Aircraft must undergo repetitive inspections of the internal fuselage structure to detect cracks, following the technical rules set out in American aviation safety notice FAA AD 2006-05-02 and Boeing Alert Service Bulletin 747-53A2500.

Why it matters: Fatigue testing revealed that certain areas of the fuselage main frame can develop cracks over time. Without these inspections, structural failures could occur, potentially endangering the aircraft and passengers.
