The FAA's summary their words, unchanged

The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes. This AD was prompted by a report of a landing gear not locked indication during the final approach, which led the flight crew to declare an emergency. This AD requires reviewing maintenance records of the main landing gear (MLG) assemblies to determine whether the MLG was modified according to a certain service bulletin or restored during overhaul maintenance; inspecting the left and right MLG locking-stay bracket assemblies to verify that the correct attaching hardware is correctly installed on the brackets; replacing nuts having certain part numbers (P/Ns); replacing the locking-stay bracket assembly, if necessary; and prohibits the installation of affected parts on the MLG locking-stay bracket assembly; 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.

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: 2024-12-08 Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.): Amendment 39-22772; Docket No. FAA-2024-1688; Project Identifier MCAI-2024-00299-T. (a) Effective Date This airworthiness directive (AD) is effective July 11, 2024. (b) Affected ADs None. (c) Applicability This AD applies to Embraer S.A. (Type Certificate previously held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes, and Model ERJ 170-200 LR, -200 SU, -200 STD, and -200 LL airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) Emergency AD E2024-05-09R01, effective May 29, 2024 (ANAC AD E2024-05-09R01). (d) Subject Air Transport Association (ATA) of America Code 32, Landing gear. (e) Unsafe Condition This AD was prompted by a report of a landing gear not locked indication during the final approach, which led the flight crew to declare an emergency. The FAA is issuing this AD to address failure of the main landing gear (MLG) locking-stay bracket assembly due to failure of this self-locking nut, which can result in uncommanded retraction of the landing gear and consequent loss of directional control of the airplane on the ground if the landing gear collapses. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, ANAC AD E2024-05-09R01.

(2) Where ANAC AD E2024-05-09R01 refers to its effective date, this AD requires using the effective date of this AD.

For this AD, after accomplishing the inspection required by paragraph (b)(2) or (c)(2), as applicable, of ANAC AD E2024-05-09R01, the actions required by paragraphs (b)(2)(i), (b)(2)(i)(I), (c)(2)(i), and (c)(2)(i)(I) of ANAC AD E2024-05-09R01 must be done before further flight, if there is no anomaly in the hardware installation on the bracket P/N 1840A0700-03 or 1840A0700-04, or nut having P/N MS17826-5 installed, as applicable. (4) Where paragraph (e) of ANAC AD E2024-05-09R01 refers to "After the effective date of this AD," for this AD, replace that text with "As of the effective date of this AD."
