Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to 

regulations.gov, including any personal 

information you provide. The agency 

will also post a report summarizing each 

substantive verbal contact received 

about this final rule. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this AD contain 

commercial or financial information 

that is customarily treated as private, 

that you actually treat as private, and 

that is relevant or responsive to this AD, 

it is important that you clearly designate 

the submitted comments as CBI. Please 

mark each page of your submission 

containing CBI as ‘‘PROPIN.’’ The FAA 

will treat such marked submissions as 

confidential under the FOIA, and they 

will not be placed in the public docket 

of this AD. Submissions containing CBI 

should be sent to Joshua Bragg, Aviation 

Safety Engineer, FAA, 1600 Stewart 

Avenue, Suite 410, Westbury, NY

commentary that the FAA receives 

which is not specifically designated as 

CBI will be placed in the public docket 

for this rulemaking. 

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 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 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 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 88, No. 230 / Friday, December 1, 2023 / Rules and Regulations 83819 

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. 

List of Subjects in 14 CFR Part 39

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

ATR—GIE Avions de Transport 

Re ́gional Model ATR42–500 and

prompted by reports of loose fasteners 

and cracks in the horizontal stabilizer

inspection of the HS affected areas for 

discrepancies and applicable corrective 

action, as specified in a European Union 

Aviation Safety Agency (EASA) AD, 

which is incorporated by reference. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective January 5, 

2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of January 5, 2024.
