Models named: BD-100-1A10. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all Bombardier, Inc., Model BD-100-1A10 airplanes.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

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.

Unsafe condition

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. The FAA is issuing this AD to address intermittent and repetitive messaging, which increases overall workload and introduces a risk that flightcrews could become desensitized over time to the messages. This could result in the required checklist not being carried out or completed, and could adversely affect the airplane's continued safe flight and landing.

Affected ADs

None.
