FAA Issues Revised Airworthiness Directive for Boeing 747-100B, 747-200B, 747-300, 747-400, and 747-400D Series Airplanes

The Federal Aviation Administration (FAA) has updated an existing airworthiness directive for Boeing 747-100B, 747-200B, 747-300, 747-400, and 747-400D series airplanes, as well as for 747-200B series airplanes with a stretched upper deck, to reduce the frequency of inspections for potential issues with the tension ties, shear webs, and frames, following reports of multiple severed adjacent tension ties and other defects.
