Airworthiness Directive · Amendment 39-22481 · Doors
BAE Systems (Operations) Limited Airplanes
This AD applies to all BAE Systems (Operations) Limited Model 4101 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model 4101 airplanes. This AD was prompted by in-service cracking of the passenger door edge member, seal carrier, and inner skin, adjacent to the roller guide bracket. This AD requires a one-time inspection of the external visible surface of the inner skin, door edge member, and seal carrier adjacent to the roller bracket attachment brackets; and the inner skin, door edge member, and seal carrier at the roller bracket attachment bore, and repair if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
At the applicable time specified in paragraph (g)(1) or (2) of this AD, accomplish an eddy current inspection of the external visible surface of the inner skin, door edge member, and seal carrier adjacent to the roller bracket attachment brackets for cracking; and an eddy current inspection of the inner skin, door edge member, and seal carrier at the roller bracket attachment bores for cracking, in accordance with paragraph 2.B. of the Accomplishment Instructions of BAe JETSTREAM Series 4100 Service Bulletin J41-52-065, Revision 1, dated June 8, 2022.
(1) For airplanes that have accumulated 18,000 total flight cycles or fewer as of the effective date of this AD: Accomplish the inspections prior to the accumulation of 20,000 total flight cycles.
(2) For airplanes that have accumulated more than 18,000 total flight cycles as of the effective date of this AD: Accomplish the inspections within 2,000 flight cycles after the effective date of this AD.
If, during any inspection required by paragraph (g) of this AD, any crack is detected: Before further flight, repair using a method approved by the Manager, International Validation Branch, FAA; or the United Kingdom Civil Aviation Authority (U.K. CAA); or BAE Systems (Operations) Limited's U.K. CAA's (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
Although BAe JETSTREAM Series 4100 Service Bulletin J41-52-065, Revision 1, dated June 8, 2022, specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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, International Validation Branch, mail it to the address identified in paragraph (k)(2) of this AD or email to: 9-AVS-AIR-730-AMOC@faa.gov. If mailing information, also submit information by email. 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 the U.K. CAA; or BAE Systems (Operations) Limited's U.K. CAA's Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
(1) Refer to U.K. CAA G-2022-0019, dated October 31, 2022, for related information. This U.K. CAA AD may be found in the AD docket at regulations.gov under Docket No. FAA-2023-0929.
