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

Applicability*9

This AD applies to Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category, serial numbers 20003 through 20500 inclusive, and 20501 through 20867 inclusive.

Compliance

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

Required actions

Within 30 days after the effective date of this AD, revise the existing AFM to include the information specified in “Autoflight” procedure in Section 02-04, “System Limitations,” of the LIMITATIONS section, and “Engine Failure in Climb During (V) ALTS CAP or (V) ALTV CAP,” procedure in Section 03-32, “Powerplant,” of the EMERGENCY PROCEDURES section; of the Bombardier Challenger 300 Airplane Flight Manual (Imperial Version), Publication No. CSP 100-1, Revision 69, dated July 4, 2022 (for airplanes having serial numbers 20003 through 20500 inclusive); or the Bombardier Challenger 350 Airplane Flight Manual, Publication No. CH 350 AFM, Revision 34, dated June 14, 2022 (for airplanes having serial numbers 20501 through 20867 inclusive); as applicable. Note 1 to paragraph (g): For obtaining the procedures for Bombardier Challenger 300 AFM (Imperial Version), Publication No. CSP 100-1, use Document Identification No. CH 300 AFM-I. Note 2 to paragraph (g): For obtaining the procedures for Bombardier Challenger 350 AFM, Publication No. CH 350 AFM, use Document Identification No. CH 350 AFM.

Unsafe condition

This AD was prompted by a report that during altitude capture flight, the flight guidance/autopilot does not account for engine failure while capturing an altitude. The FAA is issuing this AD to address the occurrence of an engine failure during or before a climb while in altitude capture flight. The unsafe condition, if not addressed, could cause the airspeed to drop significantly below the safe operating speed and may require prompt flightcrew intervention to maintain a safe operating speed.

Affected ADs

This AD replaces AD 2020-07-13, Amendment 39-19892 (85 FR 20394, April 13, 2020) (AD 2020-07-13).
