Airworthiness Directive · Amendment 39-22491 · Time limits/maintenance checks
Bombardier, Inc., Airplanes
This AD applies to all Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by an in-service event where the nose gear door amber caution message displayed on the crew alerting system during the initial climb after gear retraction. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. 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 maintenance and inspection program, as applicable, to incorporate the information specified in Bombardier Challenger 300 BD-100 Time Limits/Maintenance Checks Temporary Revision (TR) TR5-2-101, dated June 30, 2022; or (Bombardier) Challenger 350 BD-100 Time Limits/Maintenance Checks TR TR5-2-30, dated June 30, 2022; as applicable. The initial compliance time for doing the tasks is at the time specified in Bombardier Challenger 300 BD-100 Time Limits/Maintenance Checks Temporary Revision (TR) TR5-2-101, dated June 30, 2022; or (Bombardier) Challenger 350 BD-100 Time Limits/Maintenance Checks TR TR5-2-30, dated June 30, 2022; as applicable, or within 60 days after the effective date of this AD, whichever occurs later.
After the existing maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals, may be used unless the actions and intervals, are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i)(1) of this AD.
