Airworthiness Directive · Amendment 39-22881 · Time limits/maintenance checks
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes, certificated in any category, serial numbers 9002 through 9998 inclusive, and 60001 through 60046 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations for certain brake accumulators are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD also requires determining the accumulated landings on the affected brake accumulators. The FAA is issuing this AD to address the unsafe condition on these products.
Within 90 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information in the tasks specified in table 1 to paragraph (g) of this AD of Section 5-10-11, “Life Limits (Systems),” of Part 2, “Airworthiness Limitations,” of the applicable Time Limits/Maintenance Checks (TLMC) Manual. The initial compliance time for doing the tasks is at the time specified in the tasks specified in table 1 to paragraph (g) of this AD, or within 90 days after the effective date of this AD, whichever occurs later.
