More than 16 years after a crash of an Air France plane between Rio de Janeiro and Paris, which claimed the lives of 228 people on board, the airline and aircraft manufacturer “Airbus” will stand trial on charges of involuntary manslaughter.

An appeals court in Paris is scheduled to review the case this Monday. The two companies face potential fines of up to 225,000 euros (263,000 dollars).

Both Air France and Airbus have consistently denied responsibility for the disaster.

Flight AF447 disappeared from radar screens on June 1, 2009, after a storm caused turbulence while it was en route from Rio to the French capital. The Airbus A330 crashed into the Atlantic Ocean, killing all 228 people on board.

The cause of the disaster remained unclear for years, and the last victims’ bodies and the plane’s data recorder were only recovered in May 2011 from a depth of about 4,000 meters.

This crash was the deadliest in the history of Air France.
