Metal Part Maybe Came From Continental Jet

Sept. 4, 2000 -- French investigators today said a stray metal piece that gashed a tire of a supersonic Concorde in July — causing a fire in the fuel tank and dooming the flight — apparently came from a Continental Airlines DC-10.

The Continental jet took off from the same runway just minutes before the Concorde, which caught fire and crashed into a hotel, killing 113 people, said France’s Accident and Inquiry Office.

The plane, inspected on Saturday in Houston, had a missing part “which appeared to be identical to the metal piece found on the runway after the July 25, accident,” read a statement from the office, known by the French acronym, BEA.

Foreign Object Debris

The BEA’s preliminary report on the accident, made public Thursday, showed a picture of a bent metal piece nearly 17 inches long, similar to a part later found to be missing from a space between a fan and a door on the right-wing engine of the Continental DC-10.

But the BEA statement described the found metal piece as part of a hood on a thrust reverser.

It was not immediately confirmed that the two pieces are the same. But Jane’s aviation security editor Chris Yates said that two types of parts could be confused with each other.

BEA spokeswoman Helene Bastianelli said that it was “probably” the same part.

A Continental spokeswoman noted that “it has notbeen determined definitively” that the missing part on itsaircraft was the piece found on the runway.

Small parts falling off aircrafts are often not noticed. “Parts do not routinely fall off of airplanes,” said John Nance, ABC aviation expert. “The big piece of a KLM jet that landed on a California beach last week was most unusual.”

But often, when parts as small as a 17-inch metal strip do fall off of an aircraft, alarms do not go off in the cockpit, and they are not noticed.

Small pieces of junk found on the runway are so common, they even have a name: FOD, or foreign object debris. They can range from a mechanic’s wrench to a suitcase.

Yated believes that incidents of debris falling off aircrafts, while not common, do happen with an alarming regularity. “That’s the whole purpose of runway inspections,” he said.

Runway Inspection Postponed

French investigators earlier said a routine inspection of the runway from which the Concorde took off had been delayed. Paul-Louis Arslanian, head of the Air Accident Investigation Bureau (BEA), told a news conference Friday a fire drill on the runway was taking place and theinspection was postponed due to personnel shortages.

However, it is unclear if the routine inspection, which was scheduled for 3 p.m., would have altered the chain of events on July 25, since the Continental flight took off mere minutes before the Concorde.

That would eliminate pointing a finger at airportofficials for having postponed the cleaning to allow for a fire drillon the runway. The postponed cleanup was briefly mentioned in the75-page preliminary report.

It was not immediately known whether there might be any legalimplications for Continental.

Early Suspicions

Investigators have all along speculated that the part came fromanother airplane. The picture shows a bent part, reddish on oneside and greenish on the other, with rivet holes.

The BEA was convinced early on that the metal part destroyed aleft forward tire. Huge chunks of rubber were then thrust at highvelocity toward the fuel tanks in the Concorde’s delta-shapedwings, causing a fuel leak and a huge fire.

The flight, filled with German tourists, dived into a smallhotel, less than two minutes after takeoff. It was the firstaccident by the supersonic Concorde since it entered commercialservice 24 years ago.

Concorde Could Be Airborne Again

Meanwhile, Air France Chief Executive Officer Pierre-HenriGourgeon raised the possibility that the Concorde could be airborneagain by May 2001. It was the first time any date has been givensince France and Britain officially grounded their fleets inAugust.

“There are many uncertainties and May would seem to be theearliest possible date,” he told reporters. “Experts haven’t yetmade their recommendations,” so costs to modify the aircraft arenot known, he added.

French Transport Minister Jean-Claude Gayssot has said the planewill not be certified as airworthy until investigators can unlockthe “catastrophic chain of events” that led to the crash.

The only two existing Concorde fleets — in France and Britain — were both officially grounded in August until further notice.

The Concorde, which flies across the Atlantic at Mach 2, twicethe speed of sound, has been the most sophisticated form ofcommercial transatlantic air travel.
