Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus transport category airplanes. This proposed AD would require replacing the existing cabin altitude indicator in the cabin pressure control panel with a new, improved cabin altitude indicator. This proposed AD is prompted by a report of injuries occurring on in- service airplanes when crewmembers forcibly initiated opening of passenger/crew doors against residual pressure causing the doors to rapidly open. We are proposing this AD to prevent injury to crewmembers, and subsequent damage to the airplane caused by rapid opening of the door.
