Abstract
The FAA is superseding Airworthiness Directive (AD) 2023-23- 10, which applied to all Embraer S.A. Model ERJ 190-300 airplanes. AD 2023-23-10 required 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. Since the FAA issued AD 2023-23-10, it was determined that certain requirements needed to be clarified. This AD continues to require all actions of ANAC AD 2023-06-01 with revised compliance requirements, 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.

-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2023-23-
10, which applied to all Embraer S.A. Model ERJ 190-300 airplanes. AD
2023-23-10 required 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. Since
the FAA issued AD 2023-23-10, it was determined that certain
requirements needed to be clarified. This AD continues to require all
actions of ANAC AD 2023-06-01 with revised compliance requirements, 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.

Background
The FAA issued AD 2023-23-10, Amendment 39-22612 (88 FR 83817,
December 1, 2023) (AD 2023-23-10), for all Embraer S.A. Model ERJ 190-
300 airplanes. AD 2023-23-10 was prompted by an MCAI originated by
ANAC, which is the aviation authority for Brazil. ANAC issued AD 2023-
06-01, effective June 16, 2023 (ANAC AD 2023-06-01), to correct an
unsafe condition.
AD 2023-23-10 required 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, which is incorporated by reference. The FAA issued AD 2023-23-
10 to address a limit cycle oscillation phenomenon, which could expose
the surrounding structure and systems to unacceptable vibration levels
and reduce the airplane controllability.
Actions Since AD 2023-23-10 Was Issued
Since the FAA issued AD 2023-23-10, ANAC superseded ANAC AD 2023-
06-01 and issued ANAC AD 2023-06-01R1, effective June 17, 2024 (ANAC AD
2023-06-01R1) (also referred to as the MCAI), to correct an unsafe
condition for all Embraer S.A. Model ERJ 190-300 airplanes. The MCAI
states that the
[[Page 2924]]
compliance paragraph was changed. The changes clarify that
discrepancies found during any inspection must be corrected
immediately, without any additional intervening actions.
The FAA is issuing this AD to address wear on the wing hinge
bearing assembly of the aileron surfaces that could lead to excessive
backlash. If not addressed, this backlash could result in a limit cycle
oscillation phenomenon exposing the surrounding structure and systems
to unacceptable vibration levels and reducing the airplane
controllability. You may examine the MCAI in the AD docket at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2024-2551.
Explanation of Retained Requirements
Although this AD does not explicitly restate the requirements of AD
2023-06-01, this AD retains all of the requirements of AD 2023-06-01.
Those requirements are referenced in ANAC AD 2023-06-01R1, which, in
turn, is referenced in paragraph (g) of this AD.
Material Incorporated by Reference Under 1 CFR Part 51
ANAC AD 2023-06-01R1 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 attachment 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, and 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 cotter pins 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
2023-06-01R1 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 2023-06-01R1 is incorporated by reference in this AD. This AD
requires compliance with ANAC AD 2023-06-01R1 in its entirety through
that incorporation, except for any differences identified as exceptions
in the regulatory text of this AD. Material required by ANAC AD 2023-
06-01R1 for compliance will be available at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2024-2551 after this AD is published.
FAA's Justification and Determination of the Effective Date
Section 553(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). In addition, for the
foregoing reasons, 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. For any
affected airplane that 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 x $85 per hour $0 Up to $680.
= $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
[[Page 2925]]
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 x $85 per hour $500 Up to $2,370.
= $1,870.
------------------------------------------------------------------------
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.
