...After NTSB Study
The NTSB had raised concerns about the Caravans and icing back in December. The safety board asked the FAA to require that all pilots and operators of Cessna 208 Caravan series airplanes carefully check for ice and/or snow on the wings and tail before any flight when temperatures are conducive to frost or ground icing. Also, pilots of Caravans equipped for flight into known icing conditions should be required to undergo annual training on ice safety, the NTSB said. The NTSB based its recommendations on a study of 26 icing-related accidents and incidents involving Caravans between 1987 and 2003, which resulted in at least 36 fatalities.
