Narrative:
While on approach to Hibbing runway 31 in poor weather (500 feet ceiling, fog, freezing drizzle) the first officer asked the captain if he wanted to activate wing de-icing, but the captain stated he would deice them on the ground. While over the runway threshold, the sink rate increased. Back pressure on the yoke was applied until the stall warning horn sounded. The Saab touched down hard, causing the right main gear to collapse. The fuel tank ruptured and the right wing rear spar bent upward.
PROBABLE CAUSE: "The first officer's failure to maintain a proper descent rate during the landing, and the captain's inadequate supervision by not taking timely action to ensure a safe landing. Factors which contributed to the accident were: the company's failure to provide adequate training on the airplane's flight characteristics and/or handling techniques under conditions of wing ice contamination, the company's failure to assure that both pilots had received the current crew resource management (CRM) training, and the existing weather conditions which resulted in an accumulation of ice on the airplane's wing."
