Part 121 Activation of Ice Protection

View Comment

In response to the Cessna Citation 560 aircraft which crashed in Pueblo, Colorado, the pilot should have activated their deicing equipment since they knew they were flying in icing conditions. Once a pilot realizes they are in icing conditions, it’s the pilots’ responsibility for the safety of that aircraft, crew, and passengers to either use deicing equipment or get away from the icing conditions. In the Colorado crash, the airplanes AFM specified that while operating in known icing conditions, the airframe ice protection system needs to be activated, which it was not. But on the other hand, while a pilot is attempting to land, there is many things which require his attention. Landing is one of the worst times to have to worry about icing so having a warning system to remind a pilot of icing conditions would be not only convenient but increase safety overall. Thus in general, an amendment to icing conditions would increase safety for everyone in the skies, so it’s a good idea.
