Airworthiness Directive · Amendment 39-22886 · Landing gear
Embraer S.A. Airplanes
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).
The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model EMB-545 and EMB-550 airplanes. 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). This AD requires inspecting for affected MLG and NLG down lock springs and replacing affected down lock springs, and prohibits the installation of affected parts, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
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.
(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.
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.
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, send it to the attention of the person identified in paragraph (k) of this AD and email to: AMOC@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 ANAC; or ANAC's authorized Designee. If approved by the ANAC Designee, the approval must include the Designee's authorized signature.
