Boeing Proposes Airworthiness Directive for 747-200B, -300, -400, -400D, and -400F Series Airplanes

Summary

Boeing is proposing a new airworthiness directive to inspect and potentially replace mid-pivot bolt assemblies on certain 747-200B, -300, -400, -400D, and -400F series airplanes due to incorrect installation during strut modification, which could lead to fatigue cracking and engine separation during flight.
