Airworthiness Directive · Amendment 39-18622 · Navigation
Bombardier, Inc. Airplanes
This AD applies to all Bombardier, Inc. Model CL-600-2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet Series 900) airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for all Bombardier, Inc. Model CL-600-2D15 (Regional Jet Series 705) and CL- 600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by two in-service incidents reported on Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes regarding a loss of all air data information in the flight deck. This AD requires revision of the airplane flight manual (AFM) to provide procedures to guide the crew to stabilize the airplane's airspeed and attitude for continued safe flight. We are issuing this AD to prevent loss of air data information that may affect continued safe flight.
Within 30 days after the effective date of this AD, revise the Emergency Procedures section of the AFM to include the information in Emergency Procedure 1., Unreliable Airspeed, of Section 03-19, Emergency Procedures—Unreliable Airspeed, of Chapter 3, Emergency Procedures, in Volume 1 of the Bombardier CRJ Series Regional Jet CL-600-2D15 and CL-600-2D24 AFM CSP C-012, Revision 11A, dated May 25, 2015.
