The Paris Court of Appeal found Airbus and Air France guilty of corporate manslaughter over the 2009 crash of Flight AF447, reversing a lower court’s acquittal and assigning responsibility to both companies for France’s deadliest aviation disaster.

The Airbus A330 was travelling from Rio de Janeiro to Paris on June 1, 2009, when it disappeared over the Atlantic with 216 passengers and 12 crew members aboard. Everyone on the aircraft died. The flight recorders were recovered only after a deep-sea search that took two years.

Investigators concluded that ice obstructed the aircraft’s pitot tubes, the sensors used to determine airspeed, during a storm. The unreliable readings caused the autopilot to disengage and generated cockpit alarms. The pilots then placed the aircraft into a climb, after which it stalled and fell into the ocean.

The long-running criminal case examined whether Air France and Airbus had committed negligent failures that contributed to the chain of events. Lawyers representing victims’ families argued that the companies were aware of problems affecting the pitot tubes and that pilots had not received adequate preparation for the emergency created when the instruments malfunctioned at high altitude.

The companies had denied criminal responsibility and emphasized pilot error. During the appeal proceedings, an Air France lawyer acknowledged that the airline had the means to provide high-altitude training but said it sincerely believed such instruction was unnecessary at the time. A lower court acquitted both companies in 2023 before the case returned on appeal.

The appeals court ruled that Airbus and Air France were solely and fully responsible for the crash. It imposed a payment of €225,000, reported as the maximum corporate manslaughter penalty, for each passenger. The supplied report described the financial penalties as largely symbolic but said the decision followed an eight-week trial that families regarded as a final opportunity for judicial recognition of responsibility.

Airbus said it would challenge the ruling before France’s highest court. The manufacturer argued that the decision was inconsistent with the prosecutors’ submissions and the previous acquittal. That planned appeal meant the May 21 judgment did not necessarily conclude the litigation.

The verdict nevertheless represented a major reversal in a case that had extended for more than a decade and focused attention on the interaction between aircraft systems, airline training and cockpit decisions. It did not change the technical sequence established by investigators; instead, it changed the legal assessment of whether corporate conduct in the years before the flight amounted to manslaughter.

For the relatives of 228 victims, the appeals ruling provided the finding of corporate guilt that the 2023 trial had denied, while the next appeal left open whether that judgment would become final.
