1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2025-01-01 Britten-Norman Aerospace Ltd.: Amendment 39-22925; Docket No. FAA-2024-1299; Project Identifier MCAI-2023-00237-A. (a) Effective Date This airworthiness directive (AD) is effective March 11, 2025. (b) Affected ADs None. (c) Applicability This AD applies to Britten-Norman Aerospace Ltd. airplanes, certificated in any category, fitted with Fairey Hydraulics Ltd or Britten-Norman Aircraft landing gear and associated landing gear components, identified in paragraphs (c)(1) and (2) of this AD. (1) Model BN-2, BN-2A, BN-2A-2, BN-2A-3, BN-2A-6, BN-2A-8, BN-2A-9, BN-2A-20, BN-2A-21, BN-2A-26, BN-2A-27, BN-2B-20, BN-2B-21, BN-2B-26, BN-2B-27, BN-2T, BN2T-4R, and BN2T-4S airplanes. (2) Model BN2A MK. III, BN2A MK. III-2, and BN2A MK. III-3 airplanes. (d) Subject Joint Aircraft System Component (JASC) Code 3200, Landing Gear System. (e) Unsafe Condition This AD was prompted by the determination that in order to ensure the continued structural integrity of certain landing gear and associated components, it is necessary to require removal of these components from service prior to exceeding established fatigue lives. Exceeding the established fatigue life, if not addressed, could result in failure of the structural integrity of the landing gear and associated components, which could result in damage to the airplane and injury to occupants. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Definitions For the purpose of this AD: (1) An "affected part" is a main landing gear (MLG), nose landing gear (NLG), or component identified in Table 1, 2, or 3 of Section 6 in Britten-Norman SB 298, Issue 3, dated July 7, 2023 (Britten-Norman SB 298, Issue 3). (2) A "part eligible for installation" is an MLG, NLG, or component with a part that has been established to be below the associated fatigue life identified in Table 1, 2, or 3 of Section 6 in Britten-Norman SB 298, Issue 3. (h) Required Actions (1) Within 30 days after the effective date of this AD, determine the number of landings accumulated on the affected parts. For an unknown number of landings, calculate the number based on 3 landings per 1 hour time-in-service. (2) Before accumulating the number of landings (fatigue life) associated with the applicable affected part as identified in Table 1, 2, or 3 of Section 6 in Britten-Norman SB 298, Issue 3, or within the next 30 days after the effective date of this AD, whichever occurs later, replace any affected part with a part eligible for installation. (3) Thereafter, replace any affected part with a part eligible for installation before accumulating the fatigue life, as identified in Table 1, 2, or 3 of Section 6 in Britten-Norman SB 298, Issue 3. (i) Parts Installation Limitation As of the effective date of this AD, do not install a MLG, NLG, or associated component unless it is a part eligible for installation. (j) 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 local Flight Standards District Office, as appropriate.
