Airworthiness Directive · Amendment 39-19918 · Navigation
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category, serial numbers 20001 through 20688 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 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 to 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—Avionics (section 03-17) of the existing AFM to include the information in the “Unreliable Airspeed” procedure of the applicable AFM specified in figure 1 to paragraph (g) of this AD, and revise the Normal Procedures—After Take-off (section 04-04) of the existing AFM to include the information in the “Go-Around” procedure of the applicable AFM specified in figure 1 to paragraph (g) of this AD.
