This AD was 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 issuing this AD to prevent injury to crewmembers, and subsequent damage to the airplane caused by the rapid opening of the door.
