Airworthiness Directive · Amendment 39-23235 · 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 a determination that new or more restrictive airworthiness limitations are necessary. 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 90 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Part 2, “Airworthiness Limitations,” of the applicable time limits/maintenance checks (TLMC) manual identified in paragraph (g)(1) or (2) of this AD. The initial compliance time for doing the tasks specified in Part 2, “Airworthiness Limitations,” of the applicable TLMC manual identified in paragraph (g)(1) or (2) of this AD is at the time specified in the applicable TLMC manual, or within 90 days after the effective date of this AD, whichever occurs later. Using a later revision of Part 2, “Airworthiness Limitations,” of the applicable TLMC manual with information identical to the material listed in paragraph (g)(1) or (2) of this AD, as applicable, is acceptable for compliance with the requirements of this paragraph.
(1) For Model BD-100-1A10 airplanes having serial numbers (S/Ns) 20003 through 20457 inclusive: Bombardier Challenger 300 TLMC, Publication No. CH 300 TLMC, Revision 24, dated August 9, 2023.
(2) For Model BD-100-1A10 airplanes having S/Ns 20501 through 21399 inclusive: Bombardier Challenger 350 TLMC, Publication No. CH 350 TLMC, Revision 14, dated August 9, 2023.
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 or intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i)(1) of this AD.
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the manager of the International Validation Branch, send it to the attention of the person identified in paragraph (j) of this AD and email to: AMOC@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office.
(2) Contacting the Manufacturer: For any requirement in this AD to obtain instructions from a manufacturer, the instructions must be accomplished using a method approved by the Manager, International Validation Branch, FAA; or Transport Canada; or Bombardier, Inc.'s Transport Canada Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.
