MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
This AD applies to MHI RJ Aviation ULC (type certificate previously held by Bombardier, Inc.) Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes, certificated in any category, as identified in Transport Canada AD CF-2023-79, dated December 21, 2023 (Transport Canada AD CF-2023-79), except for Group 3 and Group 5 airplanes identified Transport Canada AD CF-2023-79.
Note 1 to paragraph (c): Group 3 airplanes that are modified as specified in Service Bulletin 670BA-25-110 become Group 2 airplanes as identified in Transport Canada AD CF-2023-79.
Note 2 to paragraph (c): Group 5 airplanes that are modified as specified in Service Bulletin 670BA-25-057 become Group 4 airplanes as identified in Transport Canada AD CF-2023-79.
The FAA is adopting a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by a report that the electrical harnesses in the overhead bin above the class divider may have insufficient or no separation with the class divider mounting plate. This AD requires inspecting the overhead bin electrical harnesses at the class dividers and modifying the class divider mounting plate assembly or accomplishing a temporary repair if necessary; and, eventually modifying the class divider mounting plate assembly if a modification was not done after accomplishing the inspection, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Transport Canada AD CF-2023-79.
(1) Where Transport Canada AD CF-2023-79 refers to its effective date or August 7, 2023 (the effective date of Transport Canada AD CF-2023-56, dated July 24, 2023), this AD requires using the effective date of this AD.
(2) Where Transport Canada AD CF-2023-79 refers to hours air time, this AD requires using flight hours.
(3) Where paragraph A. of Part I of Transport Canada AD CF-2023-79, specifies “and, modify as required,” for this AD, replace that text with “and, before further flight, modify as required.”
(4) Where any MHIRJ service information referenced in Transport Canada AD CF-2023-79 differs from any Safran service information referenced in Transport Canada AD CF-2023-79, the MHIRJ service information takes precedence over the Safran service information because the initial revision of the Safran service information does not list all affected part numbers.
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, mail it to the address identified in paragraph (j) of this AD. Information may be emailed to: 9-AVS-NYACO-COS@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 MHI RJ Aviation ULC's Transport Canada Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.
