Air France Plane Debris Found as Search for Black Boxes Begins


June 3 (Bloomberg) -- Debris from the Air France Airbus that crashed this week was discovered by Brazilian Air Force planes at four sites in the Atlantic Ocean as a search got under way for two black box recorders that could provide clues to the cause of the disaster.

Searchers found a piece of metal measuring 7 meters (23 feet) in diameter, Colonel Jorge Amaral told reporters in Brasilia. An oil patch in the ocean extends 20 kilometers and no bodies have yet been found, he said.

Investigators will take months of gathering information to determine what caused the crash. Air France flight AF447 from Rio de Janeiro to Paris went down June 1 with 228 people aboard. Debris from the Airbus SAS A330-200 aircraft is being found about 650 kilometers (405 miles) northeast of Brazil’s Fernando de Noronha island, which is off Brazil’s northeastern coast.

A Brazilian navy vessel has arrived in the area of the crash site, said Admiral Savio Nogueira in an interview with local Globo News channel. It’s the first vessel to arrive in the area, he said.

The airplane’s two black boxes -- one which provides records of pilot communications, and the other, a record of technical data relating to the plane’s performance -- may be harder to find, as the water in the area where the plane disappeared is extremely deep, French investigators said today.

“I’m not optimistic. It’s not only deep but mountainous in that part of ocean,” Paul-Louis Arslanian, director of the body conducting the inquiry, told journalists at a press conference in Paris today. “Recorders can be a great help but aren’t essential to an investigation.”

The boxes emit signals that can be captured over one kilometer for 30 days following any accident. He said the signals would be faint.

Triangulation

Investigators are using a process known as “triangulation,” to locate the black boxes, Arslanian said. The recorders are at a minimum depth of 1,000 meters.

Early investigations into the crash show there was no evidence of technical problems with the aircraft before takeoff and that the pilot’s last communication was about bad weather, he also said.

Arslanian, who promised an initial public report on the accident by the end of June, said the information investigators have so far is patchy and doesn’t show where and when the crash occurred.

“I don’t have data to know if the plane broke up in air or at sea,” Arslanian said at the conference. He said the last conversation recorded between the pilots and air traffic controllers focused on weather conditions, though he declined to give any detail.

Location of Wreckage

The plane probably flew into thunderstorms that stretched for 600 kilometers, towered as high as 15,000 meters and may have produced lightning, State College, Pennsylvania-based AccuWeather.com said yesterday in a statement.

The wreckage may be located at a depth of 2,000 to 3,000 meters (6,600 to 9,800 feet), French Energy Minister Jean-Louis Borloo said today.

“Did we enter a period of climate shocks of an extraordinary violence? This is a question we will have to ask ourselves,” Borloo said. “Experts are divided on that question.”

Some of the plane’s exterior sensors had frozen, Borloo said on France’s RMC radio, confirming a report on the Web site of the weekly magazine Le Point. The magazine also said the last transmission from the plane concerned electrical failures.

The floating piece of metal could be “a piece of wing, a part of the fuselage, a part of the tail, we still don’t know yet,” said Brazilian Air Force spokesman Amaral. “Still, it’s a considerable piece.”

Thunderstorms

Arslanian, who oversaw the investigation of Air France’s Concorde crash in 2000, said that the independent investigating agency will release information as quickly as possible, and cautioned against listening to speculation from people on the fringes seeking to judge how the accident may have occurred.

Arslanian is head of the BEA, the official French organization responsible for technical investigations of civil aviation accidents and incidents. Created in 1946, it’s attached to the Ministry of Transportation and acts independently.

A separate investigation is being carried out by the French prosecutor’s office to figure out who is responsible. Arslanian said he found it “normal” that there should be a parallel, judicial inquiry.

‘Who Is Guilty?’

“Someone has to answer the question: ‘who is guilty’? ” he said. “That’s not my role.”

The boxes are designed to sink not float because if they are tossed around on the surface of the water it might be even more difficult to track them, given the constant displacement. This investigation “is difficult but not the most difficult we’ve ever had, ” Arslanian said.

Brazil and France dispatched spotter planes, helicopters and navy vessels to locate the plane. The U.S. military is also assisting in the search.
