Airworthiness Directive · Amendment 39-19769 · Navigation
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., airplanes, certificated in any category, identified in paragraphs (c)(1) through (3) of this AD.
(1) Model CL-600-1A11 (600), serial numbers 1001 through 1085 inclusive.
(2) Model CL-600-2A12 (601), serial numbers 3001 through 3066 inclusive.
(3) Model CL-600-2B16 (601-3A and 601-3R Variants), serial numbers 5001 through 5194 inclusive.
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.
Within 30 days after the effective date of this AD: Revise the Emergency Procedures section of the existing AFM to include the information in the “Unreliable Airspeed Procedure,” specified in Unreliable Airspeed, of the applicable AFM specified in figure 1 to paragraph (g) of this AD.
