Background The ANAC, which is the aviation authority for Brazil, has issued ANAC AD 2023–03–01, effective March 6, 2023 (ANAC AD 2023–03–01) (also referred to as the MCAI), to correct an unsafe condition for certain Embraer S.A. Model EMB–135BJ airplanes. The MCAI states that missing sealant was identified on the rivets installed in the interface between rib 3 and the wing skin in some Embraer Model EMB– 135BJ airplanes. The lack of sealant when a failure on the rivet installation exists may result in a potential ignition source inside the fuel tank during a lightning strike, which, combined with flammable fuel vapors, could result in a E:\FR\FM\30AUP1.SGM 30AUP1 59814 Federal Register / Vol. 88, No. 167 / Wednesday, August 30, 2023 / Proposed Rules 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 NPRM after determining that the unsafe condition described previously is likely to exist or develop in other products of the same type design. fuel tank explosion and consequent loss of the airplane. The FAA is proposing 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–2023–1807. Related Service Information Under 1 CFR Part 51 ANAC AD 2023–03–01 specifies procedures for applying sealant on the rivets installed in the interface between rib 3 and wing skin. 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 ADDRESSES. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in ANAC AD 2023–03–01 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD. 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 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, the FAA proposes to incorporate ANAC AD 2023–03–01 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with ANAC AD 2023–03–01 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information required by ANAC AD 2023–03–01 for compliance will be available at regulations.gov under Docket No. FAA–2023–1807 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 10 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Up to 7 work-hours × $85 per hour = $595 ..................................................................... The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators. lotter on DSK11XQN23PROD with PROPOSALS1 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. VerDate Sep<11>2014 17:02 Aug 29, 2023 Jkt 259001 Regulatory Findings The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 Cost per product $0 Up to $595 ..........

Background

    The ANAC, which is the aviation authority for Brazil, has issued 
ANAC AD 2023-03-01, effective March 6, 2023 (ANAC AD 2023-03-01) (also 
referred to as the MCAI), to correct an unsafe condition for certain 
Embraer S.A. Model EMB-135BJ airplanes. The MCAI states that missing 
sealant was identified on the rivets installed in the interface between 
rib 3 and the wing skin in some Embraer Model EMB-135BJ airplanes. The 
lack of sealant when a failure on the rivet installation exists may 
result in a potential ignition source inside the fuel tank during a 
lightning strike, which, combined with flammable fuel vapors, could 
result in a

[[Page 59814]]

fuel tank explosion and consequent loss of the airplane.
    The FAA is proposing 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-2023-1807.

Related Service Information Under 1 CFR Part 51

    ANAC AD 2023-03-01 specifies procedures for applying sealant on the 
rivets installed in the interface between rib 3 and wing skin.
    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 ADDRESSES.

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 NPRM after determining that 
the unsafe condition described previously is likely to exist or develop 
in other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in ANAC AD 2023-03-01 described previously, except for any differences 
identified as exceptions in the regulatory text of this proposed 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, the 
FAA proposes to incorporate ANAC AD 2023-03-01 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
ANAC AD 2023-03-01 in its entirety through that incorporation, except 
for any differences identified as exceptions in the regulatory text of 
this proposed AD. Service information required by ANAC AD 2023-03-01 
for compliance will be available at regulations.gov under Docket No. 
FAA-2023-1807 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 10 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
             Labor cost                Parts cost           Cost per product           Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 7 work-hours x $85 per hour =              $0  Up to $595...................  Up to $5,950.
 $595.
----------------------------------------------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this proposed AD may be covered under warranty, thereby reducing the 
cost impact on affected operators.

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

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Embraer S.A. (Type Certificate Previously Held by Yabor[atilde] 
Ind[uacute]stria Aeron[aacute]utica S.A.; Embraer S.A.; Empresa 
Brasileira de Aeron[aacute]utica S.A. (EMBRAER)): Docket No. FAA-
2023-1807; Project Identifier MCAI-2023-00394-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by October 16, 2023.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Embraer S.A. Model EMB-135BJ airplanes, 
certificated in any category, having serial numbers 14501119 through 
14501165 inclusive, 14501167 through 14501215 inclusive, and 
14501217 through 14501236 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 57, Wings.

[[Page 59815]]

(e) Unsafe Condition

    This AD was prompted by reports of missing sealant on the rivets 
installed in the interface between rib 3 and the wing skin. The FAA 
is issuing this AD to address the lack of sealant on the rivets, 
which may result in a potential ignition source inside the fuel tank 
during a lightning strike when a failure on the rivet installation 
exists, which, combined with flammable fuel vapors, could result in 
a fuel tank explosion and consequent loss of the airplane.

(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, Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o

    (1) Where ANAC AD 2023-03-01 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) This AD does not adopt paragraph (c)(1) of ANAC AD 2023-03-
01.

(i) No Reporting Requirement

    Although the service information referenced in ANAC AD 2023-03-
01 specifies to submit certain information to the manufacturer, this 
AD does not include that requirement.
