Multiple independent web search results confirm that a Paris appeals court found Airbus and Air France guilty of corporate manslaughter regarding the 2009 crash.

One source (RFI) explicitly refers to the crash as 'France’s worst aviation disaster', and the claim refers to it being the worst in the country's history (likely referring to the context of the flight's origin/destination or the scale). However, the evidence provided specifically mentions it as France's worst.

Al Jazeera and other web results explicitly state that the Paris Court of Appeal ruled the companies were 'solely and entirely responsible' for the crash.

Both The Guardian and Al Jazeera report the court ordered a payment of 225,000 euros, noting it as the maximum fine for corporate manslaughter.

Confirmed by EuroNews, EL PAÍS, AeroTime, and RFI that a lower court acquitted the companies in 2023.

Confirmed by Wikipedia and other web search results regarding the date (June 1, 2009), route (Rio to Paris), and passenger/crew counts (216 passengers, 12 crew).

Multiple sources, including The Guardian, The Independent, and a cross-reference, confirm the black boxes were recovered two years later after a deep-sea search.

Although the 'Evidence for claim 8' section says no evidence found, the evidence provided for claim 7 (The Independent) explicitly states: 'In 2012, crash investigators found that the pilots had pushed the aircraft into a stall while mishandling a problem caused by iced-up air-speed sensor'.
