But the airline industry fears the government is rushing plans to require domestic carriers to use the additive. The intentional crash of the Boeing 720 jet, delayed for months by technical problems, now is scheduled for 10 a.m. CST at Edwards Air Force Base, said Nancy Lova-to, spokeswoman for the National Aeronautics and Space Administration.

NASA test pilot Fitz Fulton, sitting in a ground cockpit, will fly the plane by remote control to an altitude of about 2,000 feet, make a broad circle, then crash the jet in a 170-mph bellyflop on a gravel-covered runway. The plane will carry 73 dummies and numerous cameras and recording inim i wain aiMiririira rmms) )g iill'hl'l proposed rulemaking" early next year, stating it eventually intends to require all U.S. airlines to use the additive, Leyden said. However, numerous technical questions remain, including whether use of the additive will make jet engines less reliable and possibly cause more crashes than occur now, said Tom Tripp, technical information manager for the Air Transport Association, which represents the major U.S. carriers.

"One of our concerns is that we not ad-versely affect our primary safety mission to keep airplanes from crashing in the first place," Tripp said in a telephone interview from Washington. Our position is that it (the additive) is a technology worth studying, but Certainly not worth rushing: into, which apparently the FAA has committed itself to." Leyden said the purpose of the FAA's planned notice "is to really open a dialogue. It's going to be a controversial issue."

The crash is intended by NASA and the Federal Aviation Administration to test a variety of new safely features, including seat belts, fire-resistant windows and seat cushions and advanced flight data and cockpit voice recorders. But the primary purpose is to test the new fuel additive, called anti-misting kerosene, or AMK. The additive is designed to make jet fuel become mushy like gelatin during a crash rather than spray into a mist. Misting fuel that bursts into a fireball is responsible for about 40 percent of the fatalities in "survivable" crashes those in which passengers survive the crash impact, FAA spokesman John Leyden said from Washington.

If, expected, the additive prevents a fireball, the FAA plans to issue a "notice of EUREKA SPECIAL With 14 Karat Gold Chain Eureka 2062 Deluxe Upright Vacuum With Triple Filter Bag SPECIAL $89 i97 With 14 Karat Gold Chain Health-O-Meter Level Beam Scale 250 Starting from SPECIAL '110 The DownUnder Sleeper With 14 Karat Gold Chain Twin, Full, Queen and King 100 Menno Lamb's Wool for restful sleep.

Its manufacturer said last summer the earliest date it could go into effect would be 19H9. i- Because jet fuel will not burn with the' additive, jets that use it must be retrofitted with "degraders" to remove the additive before the fuel enters the engines.

Only five, prototype degraders have been built, ahcf four will be destroyed in the weekend crash, Tripp said. An lines want to make sure degraders will work properly because "if the degrade fails, the engine fails," he said. Small amounts of water contaminate fuel' on many jets, but the industry has learned to; deal with the problem. Tnpp said that when water gets into fuel mixed with the additive, though, the fuel also forms "a Jello-like blob" that' "essentially would shut the eft-' gmes down" and cause a crash. So airlines would "have to devise new methods and fuel' systems to prevent any water "contarnma-tion whatsoever," he said A Panasonic SPECIAL With 14 Karat Gold Chain Panasonic Clock Radio Telephone RCT-400 SPECIAL $239 With -14 Karat Gold Chain Smith Corona 8ELF Super Correct Electric Typewriter With Carrying Case.
