The FAA's summary their words, unchanged

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A and 601-3R Variants) airplanes. This AD was prompted by reports of the loss of all air data system information provided to the flightcrew, which was caused by icing at high altitudes. This AD requires revising the existing airplane flight manual (AFM) to provide the flightcrew with procedures for ``Unreliable Airspeed'' that stabilize the airplane's airspeed and attitude. The FAA is issuing this AD to address the unsafe condition on these products.
