FAA Orders New Steps to Strengthen Cockpit Doors > January 11, 2002 06:46 PM ET > By John Crawley WASHINGTON (Reuters) - U.S. airlines were ordered Friday to install new cockpit doors to prevent intrusion and resist certain gunfire and explosives on more than 6,000 commercial aircraft. The Federal Aviation Administration action went beyond temporary steps already taken by big carriers to secure the cockpit after the Sept. 11 hijack attacks. The temporary measures included the installation of bars and deadbolts to reinforce the doors and steps to limit general access to the flight deck. The suspects in the Sept. 11 attacks apparently made their way into the cockpits of four airliners and took over the controls. Two planes crashed into the World Trade Center and one slammed into the Pentagon. A third crashed in Pennsylvania. Friday's order would require carriers to replace cockpit doors and its related structures on the aircraft bulkhead within 18 months at a cost to the industry of between $92.3 million and $120.7 million. The purchase and installation cost for each door is between $12,000 and $17,000, the FAA said. A federal grant program that sets aside $100 million for aviation security upgrades would help carriers finance the project. Regulators and airlines had not yet decided what replacement materials should be used. The agency also required that cockpit doors be designed to prevent passengers from opening them without permission from the pilot. A locking device will be developed so that it can only be activated from inside the cockpit. The order grew out of a new law that granted the government new authority to mandate transportation security initiatives. "Fortifying cockpit doors is a critical part of assuring the safety and security of our aviation system," Transportation Secretary Norman Mineta said in a statement. Jane Garvey, head of the Federal Aviation Administration, urged airlines to move quickly to adopt the changes. Michael Wascom, a spokesman for the Air Transport Association, said the FAA action was expected and the airlines would move toward implementing the change. "This is what we have been working on all along," Wascom said. "The short-term remedy was accomplished last year. We knew full well that the next step in the process was permanent modification." Airline pilots applauded the move after pushing for modifications. "The retrofit of all those airplanes is a major undertaking -- but a necessary one, given the new terrorist threat," said Duane Woerth, president of the Air Line Pilots Association. An FAA spokeswoman said new doors should be able to withstand an assault from the most powerful type of handgun and shrapnel from a grenade or an explosive device. They should also be able to resist intrusion from someone using physical force to enter the cockpit. The order affects only domestic operators and not flights by international carriers into the United States. But regulators said they were advising other nations of the mandate. The agency also required that cockpit doors be designed to prevent passengers from opening them without permission from the pilot. A locking device will be developed so that it can only be activated from inside the cockpit.
