The French Bureau d’Enquêtes et d’Analyses pour la Sécurité de l’Aviation Civile (BEA) has indicated that the final report into the Air France Flight 447 crash will be published on July 5, 2012.
On June 1, 2009, an Airbus A330-200 aircraft operated by Air France crashed into the Atlantic Ocean during a scheduled flight from Rio de Janeiro to Paris. The accident resulted in the deaths of 216 passengers and 12 crewmembers.
Preliminary reports from the BEA stated that the aircraft crashed following aerodynamic stall caused primarily by faulty and inconsistent airspeed sensor readings, the disengagement of the autopilot and the pilot making repeated nose-up inputs despite an abundance of stall warnings. The loss of airspeed ultimately doomed the aircraft, resulting in a rapid fall from the sky.
The reason for the faulty sensor readings is unknown at this time, but they are assumed to have been caused by the formation of ice inside the pitot tubes as a result of the aircraft travelling through severe weather along its route in the tropical convergence zone.
