Superseded. A later AD replaced this one: AD 2023-05-08. Comply with the one in force.
This AD applies to the Airbus Canada Limited Partnership (type certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Model BD-500-1A10 and BD-500-1A11 airplanes, certificated in any category, identified in paragraphs (c)(1) and (2) of this AD.
(1) Model BD-500-1A10 airplanes, serial numbers 50001 and subsequent with an original airworthiness certificate or original export certificate of airworthiness issued on or before June 18, 2020.
(2) Model BD-500-1A11 airplanes, serial numbers 55001 and subsequent with an original airworthiness certificate or original export certificate of airworthiness issued on or before June 18, 2020.
The FAA is superseding Airworthiness Directive (AD) 2019-23- 15, which applied to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2019-23-15 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. 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 specified in Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 011.00, dated June 18, 2020. The initial compliance time for doing the tasks is at the time specified in Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 011.00, dated June 18, 2020, or within 90 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), intervals, or CDCCLs may be used unless the actions, intervals, and CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i)(1) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
