Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
This AD applies to Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes, certificated in any category, with a nose radome having part number (P/N) C01204101-007 or P/N C01204101-009 and a serial number (S/N) S456997, S/N S570556, S/N S626945, S/N S866894, S/N T099675, S/N T471773, orS/N T595935.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by a report that the nose radome lightning diverter strips on certain aircraft were painted in production; paint on the diverter strips can compromise the nose radome lightning protection. This AD requires inspecting for paint on the diverter strips on the nose radome, and replacing the nose radome if necessary, 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-2022-04, dated February 14, 2022 (Transport Canada AD CF-2022-04).
(1) Where Transport Canada AD CF-2022-04 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where Transport Canada AD CF-2022-04 specifies removing and installing a nose radome using certain aircraft maintenance publication data modules, this AD also allows accomplishing those actions in accordance with Airbus Canada Limited Partnership A220 Service Bulletin BD500-538009, Issue 002, dated June 2, 2022, with the exception that the painting of the nose radome can be accomplished prior to installation, and that the following nose radome assembly part numbers may be used: P/N C01204101-003, P/N C01204101-005,P/N C01204101-007, P/N C01204101-009, and P/N C01204101-011.
(3) Where Transport Canada AD CF-2022-04 specifies removing and installing a nose radome using certain aircraft maintenance publication data modules, this AD also allows repairing nose radomes by replacing the lightning diverter strips with new, unpainted lightning diverter strips, in accordance with (Airbus Canada Limited Partnership) A220 (Aircraft Structure Repair Publication (ASRP)) Task BD500-A-J53-81-80-01AAA-664A-A, Issue 004, dated January 17, 2024.
(4) Where Airbus Canada Limited Partnership A220 Service Bulletin BD500-538009, Issue 002, dated June 2, 2022, specifies to remove and discard the nose radome, this AD allows repairing removed nose radomes by replacing the lightning diverter strips with new, unpainted lightning diverter strips, in accordance with (Airbus Canada Limited Partnership) A220 (ASRP) Task BD500-A-J53-81-80-01AAA-664A-A, Issue 004, dated January 17, 2024.
As of the effective date of this AD, no person may install, on any airplane, a nose radome having P/N C01204101-007 or P/N C01204101-009 and a S/N S456997, S/N S570556, S/N S626945, S/N S866894, S/N T099675, S/N T471773, or S/N T595935 unless the actions required by paragraph (g) of this AD have been accomplished on the nose radome.
