Based on visual study of the physical remains of the Airbus A330 that have been recovered, "we were able to see that the plane hit the surface of the water flat. Therefore everything was pushed upwards -- everthing was pushed from the bottom to the top" of the plane, he said. The 228 people killed in the crash "had no time to prepare," he said. Watch report on plane's final moments > But Bouillard said he did not have autopsy results from the bodies recovered, and did not know why no one lived through the crash. "I don't know why nobody survived," he said. "I don't know the intensity of the impact. Perhaps we will find out from the autopsies. Perhaps we will never know." Bouillard said it was still unclear what caused the crash, the deadliest in Air France's 75-year history. "Today we are very far from establishing the causes of the accident," he said. The plane was unable to fly on autopilot at the time of the crash, he added. That was because the autopilot was not receiving speed, wind or direction information, he said. "These tell us that the plane has to be, in this case, directed by the pilot," he said. He did not immediately say if the pilots were in control of Air France 447. No air-traffic controllers seem to have been monitoring the flight when it went down, investigations have found. It would normally have been "handed over" from controllers in South America to others in Africa while flying over the Atlantic, but that did not happen, Bouillard said. "We want to know why there was no concern in Dakar (in Senegal, west Africa) when this plane was not handed over," he said. Investigators will continue searching for the flight data recorder and the cockpit voice recorder -- commonly known as "black boxes" -- until July 10, he said. "They normally give a signal for 30 days. We will keep listening another 10 days," he said. Flight 447 went down in stormy weather while flying from Rio de Janeiro, Brazil, to Charles de Gaulle Airport in Paris. Brazil called off the search for bodies on June 27, having found 51 of the 228 people who died when the plunged into the sea June 1, according to the military. Investigators have also found more than 600 parts and structural components of the plane, along with luggage, Bouillard said. The wreckage is believed to be about 4,500 meters (15,000 feet) deep, amid underwater mountains and mixed in with tons of sea trash. A French nuclear submarine and other vessels are searching for the data recorders by attempting to trace their locator beacons, which send out acoustic pulses, or "pings," to searchers. The U.S. Navy has contributed two high-tech acoustic devices -- known as towed pinger locators -- which have been attached to French tug boats and can search to a maximum depth of 6,100 meters. The firm which makes the recorders, Honeywell Aerospace, has told CNN it has a 100 percent recovery record from air accidents. Honeywell said it was hard to estimate how much battery life the locator beacon on the recorders had, as it depended on the conditions, but it is typically around 30 days. The American National Transportation and Safety Board says on its Web site that large commercial aircraft and some smaller commercial, corporate, and private aircraft were typically fitted with data recorders. One recorder taped radio transmissions and sounds in the cockpit, such as the pilot's voices and engine noises, the NTSB said. Sounds of interest could be engine noise, stall warnings, landing gear extension and retraction, and other clicks and pops. From these sounds engine revs per minute, system failures, speed and the time at which certain events occurred could often be determined, the NTSB said. Communications with air traffic control, automated radio weather briefings and conversations between the pilots and ground or cabin crew were also recorded. http://www.cnn.com/2009/WORLD/americas/07/02/air.france.report/index.html **************** French say sensors not cause of Flight 447 crash French investigators say speed sensors not direct cause of Air France Flight 447 crash LE BOURGET, France (AP) -- A French investigator says speed sensors were a factor but were not the cause of the crash of Air France flight 447. Alain Bouillard, leading the investigation into the June 1 crash for the French accident investigation agency BEA, says the sensors, called Pitot tubes, were not the only factor. He says "it is an element but not the cause." One of the automatic messages emitted by the plane indicates it was receiving incorrect speed information from the external monitoring instruments, which could destabilize the plane's control systems. Experts have suggested those external instruments might have iced over. All 228 people aboard the plane were killed when it plunged into the ocean en route from Rio de Janeiro to Paris.

They also found that the plane's speed sensors had been "a factor but not the cause" of the crash. All 228 people on the plane were killed when it plunged into the ocean en route from Rio de Janeiro to Paris on 1 June. Teams looking for the plane's flight data recorders will continue operations for another 10 days. Alain Bouillard, of the BEA accident investigation agency, said the crash had been an extremely difficult one to understand. But he said an examination of the recovered wreckage led them to believe the plane probably hit the water "in the direction of flight and with a strong vertical acceleration". The BBC's Transport Correspondent Tom Symonds said if the plane had broken up in the air, pieces of the fuselage would have been found twisted in a variety of directions. Instead they showed signs of compression in one direction, resulting from the plane hitting the water on its belly. Life jackets found in the wreckage had not been inflated, indicating that the passengers had little warning of a water landing. Many factors There has been speculation that the old-style speed sensors may have given the plane's pilots faulty information. But Mr Bouillard said they had been "a factor but not the cause" of the crash. In the wake of the crash, Air France accelerated an existing programme to replace speed monitors on its Airbus planes. Mr Bouillard said there was also concern about the length of the delay between the crew failing to contact air traffic controllers in Dakar, western Africa, as planned and the alarm being raised. He said his term were "still some distance away from establishing the causes of the accident" but that the search for the Airbus A330's data recorders would be extended to 10 July. The French investigation appears to contradict earlier reports attributed to Brazilian pathologists. They said last month that the injuries sustained by the passengers whose bodies had been found suggested the plane had been in pieces before it hit the sea. Mr Bouillard said France had not yet been given access to those autopsy reports. Search teams have recovered 51 bodies from the ocean but said last month that finding any more remains was "impossible". http://news.bbc.co.uk/2/hi/europe/8130989.stm **************** Curt Lewis, P.E., CSP CURT LEWIS & ASSOCIATES, LLC
