FAA Speeds Up Boeing 737 Inspections
By MICHAEL J. SNIFFEN, Associated Press Writer


   (08-29) 07:25 PDT WASHINGTON, (AP) --

   Federal regulators ordered airlines to speed up inspections of the wing
slats on newer Boeing 737 jetliners after more problems that could lead to
a fire were found in initial inspections this week.

   In the second emergency airworthiness directive in four days, the Federal
Aviation Administration reduced the time allowed for inspecting the slat
downstop assembly from 24 days to 10.

   Both the last Saturday's directive and the superseding one issued late
Tuesday were based on findings about the fire that destroyed a China
Airlines 737 in Japan last week.

   FAA spokesman Les Dorr said the initial inspections this week had found
two planes in which parts had come off the slat downstop assembly and were
lying loose in the housing, including one in which the housing wall was
damaged.

   Last Thursday, investigators in Japan found that a bolt from a right wing
slat had pierced the fuel tank of the Taiwanese jetliner that caught fire
after landing on the Japanese resort island of Okinawa. All 165 people
aboard evacuated safely seconds before the plane exploded.

   A fuel leak through that hole likely caused the fire on the China Airlin=
es
Boeing 737-800, said Kazushige Daiki, chief investigator at Japan's
Aircraft and Railway Accidents Investigation Commission.

   Slats slide out the front edge of the main wings during takeoff and
landing to stabilize the aircraft, along with flaps that come out of the
wings' rear edge. The downstop limits how far the slats can slide out.

   The new directive said owners and operators could do either the detailed
inspection ordered initially or use a borescope, an imaging device that
can get into closed areas. Dorr said the goal was to ensure all parts were
in place, particularly a washer crucial to holding a nut on the bolt. If
no repairs were needed, airlines could take the full 24 days to retighten
the nut and bolt to specifications, the order said.

   The orders apply to 783 U.S. airplanes but will likely be imposed by oth=
er
countries on the entire worldwide fleet of 2,287 newer 737s, Dorr said.

   The order covers all 737-600, -700, -800, -900 and -900ER series planes,
the first of which entered service in January 1998 with Southwest
Airlines, which flies only 737s. In the United States, the planes also are
used by Alaska, American, Continental, Delta and other carriers. ----------=
