The FAA has issued Information for Operators (InFO) 09005, urging more and better pilot training for operating de-icing boots and for maintaining airspeed in airplanes equipped with de-icing boots.
The recommendation came about following analysis of the 2005 Circuit City Citation 560 crash in Pueblo, Colorado, the InFO document says. It recommends that training and flight-check personnel ensure that training and check rides address operating limitations and procedures for flight in icing conditions, the ice-bridging issue, when to activate boots, and appropriate airspeeds, monitoring and workload management during icing operations.
The InFO also suggests that training center evaluators and check airmen test de-icing boot knowledge and operation during practical tests and flight checks. Pilots should be certain to follow manufacturers’ recommended airspeeds in icing conditions, or a speed of 1.5 times the non-iced stall speed, it says.
