Crash report points to wiring
By Gary Stoller, USA TODAY

HALIFAX, Nova Scotia =97 An electrical wiring problem was the most likely=20
cause of a fire that caused Swissair Flight 111 to crash into the Atlantic=
=20
Ocean near here in 1998, Canadian investigators said in a report Thursday.=
=20
The 349-page report stopped short of declaring the jet's in-flight=20
entertainment system responsible for the accident, but it said that one or=
=20
more wires connected to the system short-circuited in the area where the=20
fire started. The entertainment system was made by a U.S. company,=20
Interactive Flight Technologies. After the crash, Swissair disconnected the=
=20
system from its planes and the Federal Aviation Administration, citing=20
problems with its design, banned it from airliners. The Canadian=20
Transportation Safety Board's report faulted contractors authorized to act=
=20
on the FAA's behalf who certified that the system met U.S. safety=20
standards. The report also criticized the FAA's oversight of those=20
contractors. The fire ignited insulation above the ceiling in the rear of=20
the cockpit, then spread to other flammable materials, the TSB said. All=20
229 people on the McDonnell Douglas MD-11 jet were killed.

Flight 111 was one of only a handful of jets worldwide that had the IFT=20
entertainment system, which allowed passengers to watch movies, play games=
=20
and, on some flights, gamble. USA TODAY reported Feb. 17 that the faulty=20
systems were improperly installed and certified by contractors without=20
adequate FAA oversight. The TSB said mistakes were made by contractors=20
Hollingsead International and Santa Barbara Aerospace. Hollingsead=20
employees did an electrical analysis for the entertainment system, even=20
though they had no experience with MD-11 jets, the TSB said. Neither Santa=
=20
Barbara, which certified the system met FAA safety standards, nor=20
Hollingsead had staff members familiar enough with the MD-11's electrical=20
design to judge whether the system was compatible, the TSB said. Relatives=
=20
of some crash victims criticized the report. The TSB's analysis of the fire=
=20
was "very impressive," said Mark Fetherolf, whose 16-year-old daughter,=20
Tara, was killed. But it appeared the board "didn't want the media to=20
report the headline: 'Entertainment system causes crash.' " U.S. airlines=20
are under FAA orders to remove the type of insulation that was on the=20
Swissair jet from their planes by May 2005. The TSB has made 23 safety=20
recommendations as a result of the Swissair investigation. It called for:

=95 Flammability testing requirements for airplane wiring.
=95 Review of aircraft alterations certified by contractors.
