While training for the downhill at the 2006 Winter Olympics, Montillet-Carles crashed on 13 February and was evacuated by helicopter to a nearby hospital. She suffered rib, back, and facial injuries, but still opted to defend her title two days later, but finished 28th. Several racers had complained that the downhill course was too easy, and Olympic organizers had made several changes to it. She finished fifth in the super-G five days later, then retired from competition at the end of the World Cup season.
