AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

The FAA is adopting a new airworthiness directive (AD) for all Embraer S.A. Model ERJ 190–300 airplanes. This AD was prompted by a report of unexpected wear on the wing hinge bearing assembly of the aileron surfaces found during the functional test of the aileron control system backlash. This AD requires repetitive inspections of the press-fitted bushings of the wing ailerons for migration and broken sealant, measurements of the distance between the aileron surfaces and hinge fittings, functional checks of the backlash of the wing aileron control system, and all applicable related investigative and corrective actions, as specified in an Agência Nacional de Aviação Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Background

ANAC, which is the aviation authority for Brazil, has issued ANAC AD 2023–06–01, effective June 16, 2023 (ANAC AD 2023–06–01) (also referred to as the MCAI), to correct an unsafe condition for all Embraer S.A. Model ERJ 190–300 airplanes. The MCAI states unexpected wear, which was beyond the certification limits of the airplane, was found on the wing hinge bearing assembly of the aileron surfaces during the functional test of the aileron control system backlash. Excessive backlash may result in a limit cycle oscillation phenomenon exposing the surrounding structure and systems to unacceptable vibration levels and reducing the airplane controllability.

The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–2154.

Related Service Information Under 1 CFR Part 51

ANAC AD 2023–06–01 specifies procedures for repetitive general visual inspections of the press-fitted bushings of the left-hand (LH) and right-hand (RH) wing ailerons for migration and broken sealant; repetitive detailed inspections to measure the distance between the LH and RH wing aileron surfaces and hinge fittings; repetitive functional checks of the backlash of the LH and RH wing aileron control system; and applicable related investigative and corrective actions. The related investigative actions include a detailed inspection of the torque values of the attachments parts on the LH and RH wing aileron surfaces; a general visual inspection of the press-fitted bushings on the LH and RH aileron surfaces, as applicable, for damage ( i.e., elongation, scratches, nicks) and rotation or migration ( i.e., gap between the bushing flange and lug, or broken sealant around the bushing); a general visual inspection of the sliding bushings of the LH and RH aileron surfaces, as applicable, for damage ( i.e., scratches, steps, and dents) and migration of the press-fitted bushing pair; a detailed inspection to measure the outer diameter of the sliding bushings; a detailed inspection to check the inner diameter of the press-fitted bushings of certain aileron fittings; measurement of the outer diameters of the mating sliding bushing and bolt shank; and an operational check of the aileron control system, or a rigging procedure and deflection check, as applicable. The corrective actions include retorquing the nuts and installing cotterpins on the bolts and nuts of the attachment parts on the LH and RH wing aileron surfaces; and replacing the bearings and press-fitted and sliding bushings.

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 referenced 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 2023–06–01 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 2023–06–01 is incorporated by reference in this AD. This AD requires compliance with ANAC AD 2023–06–01 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 2023–06–01 for compliance will be available at regulations.gov under Docket No. FAA–2023–2154 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
Up to 8 work-hours × $85 per hour = $680	$0	Up to $680.

The FAA estimates the following costs to do any necessary on-condition actions that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need these on-condition actions:

Estimated Costs of On-Condition Actions

Labor cost	Parts cost	Cost per product
Up to 22 work-hours × $85 per hour = $1,870	$500	Up to $2,370.

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.
