The Boeing Company Airplanes: Superseding Airworthiness Directive for 747 Models
The Boeing Company is issuing a superseding airworthiness directive (AD) for various 747 models, requiring the installation of dual-pane windows to address a safety concern related to rapid cabin pressure loss and crew incapacitation. The new directive supersedes an existing AD and removes certain airplanes from its applicability.
