Air France Flight 447 - the BBC Interviews

After more than a month, most of the wreckage and many of the victims of Air France Flight 447 remain lost at sea. The public's and the media's attention remain focused on the the causes of the crash and on the recovery of the black boxes.

This podcast features two interviews with Vincent Dowd from the BBC World Service. In the first interview on June 12th, 2009, we discussed several issues, including differences in flight control philosophy between Airbus and Boeing, and how aircraft manufacturers respond when one of their airplanes crash.

In the second interview, recorded on June 23rd 2009, we discussed the progress of the accident investigation. We also talked about how the circumstances of this accident showed how it may be possible to use advanced technologies to supplement or even replace the cockpit voice recorder and flight data recorder.

Please listen to the interviews, and feel free to send your comments or questions to AirSafe.com.

Air France Flight 447 Update for 15 June 2009


As the investigation into the crash enters its third week, ships, planes, and submarines continue to search the Atlantic Ocean for wreckage, for the bodies of the victims, and especially the black boxes. Ships, planes, and submarines from Brazil, France, the US, and other countries have searched for clues to the crash in a large area of the Atlantic ocean between Brazil and Africa. So far, a wide variety of wreckage, and the remains of about 50 of the 228 occupants, have been recovered. At least two ships with detection equipment from the US Navy are on their way to the search area, as is a French submarine. Smaller French submersibles will be used to explore the bottom of the ocean once wreckage from the aircraft is located.



Evidence Points to In-flight Breakup
Initial evaluation of 16 of the recovered bodies by the Brazilian authorities suggests that the aircraft had some sort of catastrophic event while in flight. Bodies were recovered in two areas of the ocean about 50 miles (80 km) apart. Given the amount of time that the bodies were in the water, it is unlikely that this distance was due to the actions sea currents and winds. Also, there was no indication of burns, inhaled smoke, or the effects of an explosion on the examined bodies. No water was found in the lungs, which suggests that none these 16 victims drowned, and there were extensive fractures in many of the bodies. These findings are consistent with the bodies experiencing the kind of trauma associated with impacting water at high speed.


Previous Air France Airbus Incidents

According to a report in the Times of London, there were six previous Air France incidents on Airbus aircraft since 2008 that involved “a rather incoherent cocktail of alarms” and “severe breakdowns”. These appear to have originated with malfunctioning pitot tubes in stormy weather.

In one reported incident, the crew on a flight between Paris and Tokyo issued a mayday call in turbulent weather after a loss of speed indication information resulted in the disengagement of the automatic pilot and set off several alarms. In these previous six incidents, the pilots regained control of the aircraft.

Insurance Costs
Le Monde newspaper of France estimates that the estimated insurance related costs of the accident will range between $330 and $750 million. The estimated value of the aircraft was 67.4 million euros ($94.4 million).

Other News
In a bizarre and tragic turn of events, the ANSA news agency reported that a married couple from Italy who missed the accident flight after arriving late to the airport were involved in a car accident in Austria, killing the wife and seriously injuring the husband.

Air France Flight 447 Update for 10 June 2009


Update for 10 June 2009: The number of bodies recovered has increased to 41, and Brazilian authorities have begun the process of identifying bodies. The Brazilian Air Force has also incorporated the recommended change of the pitot system in the presidential aircraft, an A319. Air France has accelerated its effort to replace pitot tubes on its A330 and A340 Airbus fleet after members of one pilots union threatened to refuse to fly the unmodified airplanes. The airline also estimates that all the affected pitot tubes will be replaced by the end of July.


The vertical stabilizer is the largest piece of the aircraft that has been recovered. It shows no outward sign of fire or explosion, and a closer examination of the damage on that stabilizer will provide clues about whether it separated from the rest of the fuselage on impact with the water or while in flight. AirSafe.com will continue to provide updates to the accident investigation as more information becomes available.

Air France Flight 447 Update for 9 June 2009

By Tuesday June 9th, the number of bodies recovered increased to 28, and a substantial amount of wreckage has been recovered, including the vertical stabilizer. The bodies and wreckage were recovered about 400 miles (640 kilometers) northeast of the Fernando de Noronha islands off Brazil's northeastern coast, and about 45 miles (70 kilometers) from where the jet was last estimated position. Equipment for locating the beacons attached to the cockpit voice recorder and flight data recorder is not yet in place, but will be in the next few days.

Naval forces from Brazil, France, and the US will all be actively involved in this search. In other developments, Air France revealed that their entire A330 fleet had been scheduled to have part of their airspeed measuring system replaced, specifically a device called a pitot tube. While some Air France A330 aircraft had the replacement done, the accident aircraft had not. There is no indication that the this device was related to the sequence of events that led to this crash. AirSafe.com will continue to provide updates to the accident investigation as more information becomes available.

Air France Flight 447 Debris Spotted


1 June 2009; Air France A330-200; Atlantic Ocean:: The aircraft was on a scheduled international flight from Rio de Janeiro, Brazil to Paris, France. The aircraft crashed in the Atlantic Ocean in an area roughly 390 miles (650 kilometers) northeast of Brazil's Fernando de Noronha islands, which are about 220 miles (354 kilometers) off the northeast coast of Brazil. Debris from the aircraft was found near the estimated position of its last radio communication. All 216 passengers and 12 crew members, together representing over 32 nationalities, are missing and presumed dead.


Recovery Efforts
Brazilian military aircraft have spotted several areas of suspected debris, and ships from Brazil and elsewhere are converging on these areas to recover any floating debris and the bodies of any crash victims. What isn't yet known is the location of any wreckage, including either of the black boxes (cockpit voice recorder and flight data recorder). Each recorder is equipped with an underwater locator beacon, also called a "pinger," which is activated when the recorder is immersed in water. It transmits an acoustical signal that can be detected with a special receiver at depths of up to 14,000 feet (over four kilometers).



Investigation and Possible Causes
The investigation is headed by the French Bureau d'Enquêtes et d'Analyses (BEA), the equivalent of the NTSB in the US or the AAIB in the UK, and the BEA will be assisted by a variety of other nations, including Brazil and the US. So far, the most direct evidence of the cause of the accident is the presence of aircraft debris on the ocean surface and a series of automatically generated maintenance messages that were transmitted from the plane shortly before the crash. According to Air France officials, these messages indicated that there were several problems with the aircraft, including some unspecified problems with the electrical system and cabin pressurization system.

While there were severe thunderstorms in the area of the crash, and some suspicion that the aircraft was hit by lightning or encountered severe turbulence, there is no direct indication that this occurred. The presence of the debris field on the ocean surface also does not imply that the aircraft broke up in flight.

AirSafe.com will update crash information as it becomes available.
