Boeing Proposes New Airworthiness Directive for 747 Series Airplanes

Boeing is proposing a new airworthiness directive to address reports of H-11 steel bolt fractures at the trailing edge flap transmissions on certain 747 series airplanes, requiring a one-time inspection and replacement of affected bolts with Inconel bolts to prevent loss of a flap transmission and reduce lateral controllability.
