Regulatory Text

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: 2023-03-16 Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.): Amendment 39-22341; Docket No. FAA-2023-0166; Project Identifier MCAI-2022-00576-T. (a) Effective Date This airworthiness directive (AD) is effective March 20, 2023. (b) Affected ADs None. (c) Applicability This AD applies to Embraer S.A. Model ERJ 190-300 airplanes, certificated in any category, serial numbers 19020009 through 19020011 inclusive. (d) Subject Air Transport Association (ATA) of America Code 32, Landing gear. (e) Unsafe Condition This AD was prompted by failed lockwires on the attachment of the left-hand main landing gear (MLG) trunnion bearing to spar 2 on a flight test airplane. These lockwires are designed to safety one shear pin to the other, keeping the integrity of the assembly through the torque applied to the shear pins. The FAA is issuing this AD to address this condition, which could result in structure vibration and possible rotation of the shear pins causing lockwire failure and shear pin migration, which could collapse the MLG structure during takeoff and landing operations. (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 2022-04-02. (h) Exceptions to ANAC AD 2022-04-02 (1) Where ANAC AD 2022-04-02 refers to its effective date, this AD requires using the effective date of this AD. (2) The "Alternative method of compliance (AMOC)" section of ANAC AD 2022-04-02 does not apply to this AD. (i) Additional AD Provisions 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.

Background ANAC, which is the aviation authority for Brazil, has issued ANAC AD 2022-04-02, effective May 3, 2022 (ANAC AD 2022-04-02) (also referred to as the MCAI), to correct an unsafe condition for certain Embraer S.A. Model ERJ 190-300 airplanes. The MCAI states that there was an occurrence of failed lockwires, having part number (P/N) MS 20995C32, on the attachment of the left-hand MLG trunnion bearing to spar 2 on a flight test airplane. These lockwires are designed to safety one shear pin to the other, keeping the integrity of the assembly through the torque applied to the shear pins. The structure vibration could cause the rotation of the shear pins causing the lockwire failure and the shear pin migration, which can collapse the MLG structure during takeoff and landing operations. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2023-0166. Related Service Information Under 1 CFR Part 51 ANAC AD 2022-04-02 specifies procedures for inspecting for damage of the left- and right-hand MLG trunnion bearing attaching parts, replacing any damaged parts and torquing shear pins, having P/N 196-32185-007 or P/N 196-32216-007, and modifying the MLG trunnion bearing attaching parts to spars 2 and 3. This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. FAA's Determination This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA's bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI described above. The FAA is issuing this AD after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Requirements of This AD This AD requires accomplishing the actions specified in ANAC AD 2022-04-02 described previously, except for any differences identified as exceptions in the regulatory text of this AD. Explanation of Required Compliance Information In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, ANAC AD 2022-04-02 is incorporated by reference in this AD. This AD requires compliance with ANAC AD 2022-04-02 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Service information required by ANAC AD 2022-04-02 for compliance will be available at regulations.gov under Docket No. FAA-2023-0166 after this AD is published. FAA's Justification and Determination of the Effective Date Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq. ) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for "good cause," finds that those procedures are "impracticable, unnecessary, or contrary to the public interest." Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. There are currently no domestic operators of these products. Accordingly, notice and opportunity for prior public comment are unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the forgoing reason(s), the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days. Regulatory Flexibility Act (RFA) The requirements of the RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. Costs of Compliance Currently, there are no affected U.S.-registered airplanes. If an affected airplane is imported and placed on the U.S. Register in the future, the FAA provides the following cost estimates to comply with this AD: Estimated Costs for Required Actions Labor cost Parts cost Cost per product 69 work-hours × $85 per hour = $5,865 $7,333 per kit Up to $20,531. According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the cost estimate. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority. The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: (1) Is not a "significant regulatory action" under Executive Order 12866, and (2) Will not affect intrastate aviation in Alaska.
