Airworthiness Directive · Amendment 39-21928 · Flight controls
Bombardier, Inc., Airplanes
This AD applies to all Bombardier, Inc., Model BD-100-1A10 airplanes.
The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by a report that the design of the spoiler control system causes certain engine indication and crew alerting system (EICAS) messages to be posted intermittently and repetitively during flight and on the ground, and flightcrews must action the appropriate checklist each time these messages appear. This AD requires revising the Non-Normal Procedures section of the existing airplane flight manual (AFM) associated with the spoiler electronic control unit (SECU) EICAS messages. 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 to incorporate the information specified in Section 05-23, Flight Controls, of Chapter 05, Non-Normal Procedures, of the AFM revisions specified in paragraphs (g)(1) and (2) of this AD, as applicable.
(1) Bombardier Challenger 300 (Imperial Version) Airplane Flight Manual, Publication No. CSP 100-1, Revision 61, dated September 25, 2020.
Note 1 to paragraph (g)(1): For obtaining this section of the Bombardier Challenger 300 (Imperial Version) Airplane Flight Manual, Publication No. CSP 100-1, use Document Identification No. CH 300 AFM-I.
(2) Bombardier Challenger 350 Airplane Flight Manual, Publication No. CH 350 AFM, Revision 27, dated September 25, 2020.
