French authorities say an array of structural problems were to blame for the collapse of a futuristic terminal at Paris' Charles de Gaulle airport last year.
The government report issued Tuesday identified four faults in the design of the terminal, including insufficient or badly positioned girders that were unable to transfer stress to other parts of the structure.
It also said extremely cold weather could have triggered the collapse of the weakened roof last May, which killed four travelers and injured several others.
A judge must now decide whether to pursue criminal proceedings against individuals involved in planning or building the terminal, including the internationally-renowned architect Paul Andreu.
Meanwhile, French authorities say they will decide in mid-April whether to repair or demolish the damaged terminal.
