Airworthiness Directive · Amendment 39-21812 · Electrical power
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category, serial numbers 20003 and subsequent.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by reports of erratic electrical system status on the push button annunciators (PBAs) and the engine instrument and crew alerting system (EICAS). This AD requires revising the existing airplane flight manual (AFM) to incorporate procedures to be applied during erroneous electrical status indication conditions. 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 Emergency Procedures and Non-Normal Procedures sections of the existing AFM to include the information in Section 03-19, Electrical, of Chapter 03, Emergency Procedures, and Section 05-19, Electrical, of Chapter 05, Non-Normal Procedures, of the Bombardier Challenger 300 (Imperial Version) Airplane Flight Manual, Publication No. CSP 100-1, Revision 63, dated April 1, 2021 (for airplanes having serial numbers 20003 through 20500 inclusive); or Bombardier Challenger 350 Airplane Flight Manual, Publication No. CH 350 AFM, Revision 29, dated April 1, 2021 (for airplanes having serial numbers 20501 through 20999 inclusive); as applicable.
Note 1 to paragraph (g): For obtaining the sections for Bombardier Challenger 300 (Imperial Version) Airplane Flight Manual, Publication No. CSP 100-1, use Document Identification No. CH 300 AFM-I.
