Reinforced flight deck doors

摘要

On September 11, 2001 the hijacking of four commercial airliners demonstrated to the world that some persons are willing to use passenger aircraft as weapons of terrorism. Following these hideous events the United States Congress enacted the Aviation and Transportation Security Act which required the strengthening of the flight deck doors. Previously, these doors were designed to give the flight crew an uninterrupted work environment so they could focus on their primary and emergency flight duties, and to provide separation from the main cabin in the event of sudden aircraft decompression. The flight deck door was never meant to be an impenetrable barrier between the cabin and the flight deck, until now. A Rapid Response Team comprising industry specialists and regulators was formed to determine the characteristics of the new door design to provide the prescribed increase in security. The Federal Aviation Administration (FAA) published Special Federal Aviation Regulation (SFAR) 92, Flightcrew Compartment Access and Door Designs on October 9, 2001, which mandated the accomplishment of certain modifications within specified time periods. Since then there have been five revisions to this SFAR, the latest being issued on April 9, 2003.
