Cessna 208 Icing Accidents (1987-2006)
For nearly 20 years, Cessna 208/208B aircraft experienced a series of icing-related crashes and incidents. The FAA and Transport Canada launched studies, issued airworthiness directives, and developed training programs addressing design flaws, pilot training gaps, and certification standards for known-icing operations. The Caravan's performance in ice accumulation became a focal point of aviation safety research.
FAA mandated low-airspeed awareness systems for Cessna 208s operating in known icing. Airworthiness directives prohibited continued flight after encountering moderate or greater icing.
Icing-related Cessna 208 accidents decreased but didn't disappear. Regulatory focus remained on equipment and pilot decision-making, not weight-and-balance documentation.
Flight 445's Cessna 208B was overweight for icing conditions and flew into forecasted moderate icing. The accident combines the aircraft type's known vulnerability to ice with the unchecked loading practices enabled by the Part 135 single-engine documentation loophole.
