AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

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 Ageˆncia Nacional de Aviac ̧a ̃o Civil 

(ANAC) AD, which is incorporated by

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10, ANAC superseded ANAC AD 2023– 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 


khammond on DSK9W7S144PROD with RULES
2924 Federal Register / Vol. 90, No. 8 / Tuesday, January 14, 2025 / Rules and Regulations 

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 

regulations.gov 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 pressfitted 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 regulations.gov 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 × $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 


khammond on DSK9W7S144PROD with RULES
Federal Register / Vol. 90, No. 8 / Tuesday, January 14, 2025 / Rules and Regulations 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 × $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.

09, which applied to all Embraer S.A. 

Model ERJ 190–400 airplanes. AD 2023– 

23–09 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 2023–23–09, 

it was determined that certain 

requirements needed to be clarified. 

This AD continues to require all actions 

of ANAC AD 2023–05–02 with revised 

compliance requirements, as specified 

in an Ageˆncia Nacional de Aviac ̧a ̃o Civil
