Airworthiness Directive · Amendment 39-21530 · Pneumatic
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category, serial numbers 20003 through 20457 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by a report of a number of low altitude engine surge incidents during takeoff. This AD requires revising the existing airplane flight manual and applicable corresponding operational procedures to provide the flightcrew with procedures to require the engine bleeds to be "ON" during takeoff. The FAA is issuing this AD to address the unsafe condition on these products.
Within 60 days after the effective date of this AD: Revise the existing AFM and applicable corresponding operational procedures to include the information in the “Air Conditioning and Pressurization” procedure in Section 02-04, “Systems Limitations,” of Chapter 02, “LIMITATIONS”; and the “Taxi and Before Takeoff” procedure in Section 04-03 of Chapter 04, “NORMAL PROCEDURES”; of the Bombardier Challenger 300 Airplane Flight Manual (Imperial Version), Publication No. CSP 100-1, Revision 63, dated April 1, 2021.
Note 1 to paragraph (g): For obtaining the procedures for Bombardier Challenger 300 Airplane Flight Manual (Imperial Version), Publication No. CSP 100-1, use Document Identification No. CH 300 AFM-I.
