Airworthiness Directives; Bombardier Inc. Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by a report that incorrect information was found in certain calculation tables in a section of the airplane flight manual (AFM) that addresses certain slat-flap conditions. This AD requires revising the Non-Normal Procedures section of the existing AFM to provide the flightcrew with corrected procedures to use in certain slat-flap conditions. The FAA is issuing this AD to address the unsafe condition on these products.
