Résumé
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-200B, 747-300, 747-400, and 747-400D series airplanes. This AD requires modifying the lateral shear beam for the Door 5 crew rest and, for certain airplanes, replacing Zone E tie rods and modifying the Zone E stowbin ladder. This AD results from a report indicating that the lateral shear beam for the Door 5 crew rest does not meet the 9G forward loading requirement. We are issuing this AD to prevent the structural support for the Door 5 crew rest and Zone E stowbins from failing, which could result in the crew rest or stowbins falling during an emergency and consequent injury to crew and passengers.
