AD and urgent safety recommendations issued to reduce Cessna 208 icing accidents
18 January 2006

The U.S. FAA adopted a new airworthiness directive (AD) for all Cessna 208 and 208B aircraft, a.o. to install deicing boots on the cargo pod and landing gear fairings. The AD (2006-01-11) resulted from reports of several accidents during operations in flight and in ground icing conditions. The AD is issued to provide a safe method to detect ice, snow, frost, or slush adhering to the upper wing prior to takeoff; and to reduce drag in-flight by shedding ice on the cargo pod and landing gear fairings.
Also, the NTSB issued three urgent safety recommendations to the FAA, advising to require all operators of Cessna 208 series airplanes to maintain a minimum operating airspeed of 120 knots during flight in icing conditions, even if a descent is required to do so; to prohibit all operators from conducting flight into any icing conditions determined to be more than light icing; and to require these operators to disengage the autopilot and fly the airplane manually when operating in icing conditions.
