## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-200B, 747-300, 747-400, and 747-400D series airplanes. This proposed AD would require 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 proposed AD is prompted by a report indicating that the lateral shear beam for the Door 5 crew rest does not meet the 9G forward loading requirement. We are proposing this AD to prevent the structural support for the Door 5 crew rest and Zone E stowbins from failing during an emergency, which could result in the crew rest or stowbins falling and consequent injury to crew and passengers.
