2024-23-07: Landing gear

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: 2024-23-07 Embraer S.A.: Amendment 39-22886; Docket No. FAA-2024-2426; Project Identifier MCAI-2024-00625-T. (a) Effective Date This airworthiness directive (AD) is effective November 20, 2024. (b) Affected ADs None. (c) Applicability This AD applies to Embraer S.A. Model EMB-545 and EMB-550 airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) Emergency AD 2024-10-02, effective October 21, 2024 (ANAC Emergency AD 2024-10-02). (d) Subject Air Transport Association (ATA) of America Code 32, Landing gear. (e) Unsafe Condition This AD was prompted by reports of corrosion, damage, and rupture on the down lock spring assemblies of the main landing gear (MLG) and nose landing gear (NLG), which, under specific load conditions on the ground, may compromise the locking and holding of the MLG and NLG in their correct kinematics positions. The FAA is issuing this AD to prevent failure of these down lock springs, which could cause a non-annunciated loss of down locking capability and result in collapse of the MLG and the NLG structure during takeoff or landing. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, ANAC Emergency AD 2024-10-02. (h) Exceptions to ANAC Emergency AD 2024-10-02 (1) Where ANAC Emergency AD 2024-10-02 refers to its effective date, this AD requires using the effective date of this AD. (2) Where Note 1 of ANAC Emergency AD 2024-10-02 defines a non-affected part 1 as "an airworthy part according to the applicable requirements and is not an affected part according to the (a)(1) paragraph of this EAD," for this AD replace that text with "an airworthy part that is not an affected part according to paragraph (a)(1) of this EAD." (3) Where Note 2 of ANAC Emergency AD 2024-10-02 defines a non-affected part 2 as "an airworthy part according to the applicable requirements and is not an affected part according to the (a)(2) paragraph of this EAD," for this AD replace that text with "an airworthy part that is not an affected part according to paragraph (a)(2) of this EAD." (4) This AD does not adopt paragraph (g) of ANAC Emergency AD 2024-10-02. (i) Returning Parts Not Required Although the material referenced in ANAC Emergency AD 2024-10-02 specifies to send removed parts to the manufacturer, this AD does not include that requirement.
