WASHINGTON - The government will order airlines to install a system to reduce the chance of fuel tank explosions like the one that downed a TWA Boeing 747 in 1996, Federal Aviation Administration chief Marion Blakey said Tuesday.





The decision affects about 3,800 Boeing and Airbus aircraft operated by domestic airlines.


In the last 14 years there have been three fuel tank explosions, including the TWA accident, resulting in 346 deaths. Blakey said the new device could eliminate up to four accidents over the next 25 years.


"We have a plan that will virtually eliminate fuel tank explosions aboard aircraft," Blakey said at a news conference.


A cost-benefit analysis still must be done and airlines need time to plan for the change, so the requirement is not expected to take effect for at least two years. Once the rule is issued, the program will be phased in over seven years. During that time existing planes will have to be retrofitted with the device and new planes will have them as standard equipment.


TWA Flight 800 crashed off the coast of Long Island, N.Y., on July 17, 1996, killing all 230 people aboard. The National Transportation Safety Board blamed the accident on an explosion, saying vapors in a partly empty fuel tank probably were ignited by a spark in the wiring.


The accident prompted FAA scientists to step up research aimed at eliminating potential ignition sources for such explosions and reducing the flammability of vapors in fuel tanks.


The device they came up with pumps nonflammable nitrogen-enriched air into fuel tanks, reducing the oxygen in fuel vapors and lessening the chance of an explosion.


In 2001, a government-industry task force concluded it would be too expensive — up to $20 billion — to retrofit airliners with the equipment necessary to pump nonflammable nitrogen into fuel tanks. The FAA estimates the cost between $600 million and $700 million, Blakey said, or between $140,000 and $220,000 per aircraft.



Last year 1,944 New Yorkers saw something and said something.

There are some serious questions as to what this order will result in.
- Will it work?
- Will the expense to install these risk reduction systems mean some a/c will
be retired sooner than planned?
- What will be the ongoing expenses to operate and maintain these systems?
- Does it create other problems or risks that may be worse than the cure?
(Nitrogen bottles on a/c, leaks of systems, electrical problems, fuel
problems ?)
- Which planes get it first? Passanger a/c? Those operating in year round
warm weather or be a/c easiest to install or if to be retired, not done at all?
- New a/c delivery delays? (ie: interest, and other costs)
- Will costs to install hurt already financially troubled airlines?
- Will older a/c not have this installed (ie: L-1011, DC-10's, 727's?)
