Overview
- The appeal opened Monday at the Paris Court of Appeal with both companies charged with negligent homicide over Flight AF447.
 - Prosecutors seek to overturn the earlier acquittal, with potential fines of up to €225,000 if convictions are returned, and 281 civil parties have joined the case.
 - Investigations concluded that iced Pitot tubes caused the loss of airspeed data and autopilot, and the disoriented crew pitched up before the jet stalled and plunged into the Atlantic.
 - First-instance judges faulted Airbus for failing to replace suspect Pitot probes promptly and faulted Air France for insufficient pilot information, yet found causation unproven.
 - The A330 disappeared on June 1, 2009 en route from Rio to Paris, killing 228 people, and its wreckage and recorders were later found in nearly 4,000 meters of water.
