## Abstract

We are adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD requires revising the airplane flight manual (AFM) to provide procedures to stabilize the airplane's airspeed and attitude. This AD was prompted by two in-service incidents of loss of all air data information in the flight deck. We are issuing this AD to address the unsafe condition on these products.
