Airworthiness Directives; Embraer S.A. (Type Certificate 
Previously Held by Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica 
S.A.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Embraer S.A. Model ERJ 190 airplanes. This proposed AD was 
prompted by a manufacturing quality escape concerning certain overheat 
detection system (ODS) sensing elements. This proposed AD would require 
inspecting the ODS sensing elements and performing applicable 
corrective actions and would prohibit the installation of affected 
parts, as specified in an Ag[ecirc]ncia Nacional de 
Avia[ccedil][atilde]o Civil (ANAC) AD, which is proposed for 
incorporation by reference (IBR). The FAA is proposing this AD to 
address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by August 30, 
2024.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

this proposal because of those comments.
    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 NPRM.

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 NPRM 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 NPRM, 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 NPRM. Submissions containing CBI should be sent to 
Joshua Bragg, Aviation Safety Engineer, FAA, 2200 South 216th Street, 
Des Moines, WA 98198; phone: 817-222-5366; email: 
[email protected]. Any 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 2023-11-02, effective November 21, 2023 (ANAC AD 2023-11-02) (also 
referred to as the MCAI), to correct an unsafe condition for certain 
Embraer S.A. Model ERJ 190-100 IGW, -100 LR, -100 SR, -100 STD, -200 
IGW, -200 LR, and -200 STD airplanes. Model ERJ 190-100 SR airplanes 
are not certificated by the FAA and are not included on the U.S. type 
certificate data sheet; this proposed AD therefore does not include 
those airplanes in the applicability. The MCAI states that a quality 
escape occurred during manufacturing concerning some ODS sensing 
elements produced before January 31, 2021. A defective sensing

[[Page 57796]]

element may not be able to detect a thermal bleed leak, which is a 
latent failure, and depending on the affected area, may start an 
ignition source in the fuel tank, which could damage some electronic 
boxes and expose the wing structure to high temperature gradients and 
unexpected thermal loads, which could result in reduced structural 
integrity of the airplane.
    ANAC has informed the FAA of an undated Errata published to correct 
a printing error in the English version of ANAC AD 2023-11-02. The FAA 
has included these corrections in paragraphs (h)(2) and (3) of this AD.
    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-2024-1704.

Related Service Information Under 1 CFR Part 51

    ANAC AD 2023-11-02 specifies procedures for a detailed inspection 
of the ODS sensing elements of the airplane bleed lines and 
replacement, if applicable, and procedures for re-activation of ODS 
sensing elements that were deactivated during the detailed inspection. 
ANAC AD 2023-11-02 also defines and prohibits the installation of an 
affected ODS sensing element unless the affected part passed an 
inspection, indicated by a marking on one face of the connector hex 
nut.
    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 2023-11-02 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 2023-11-02 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
ANAC AD 2023-11-02 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 2023-11-02 
for compliance will be available at regulations.gov under Docket No. 
FAA-2024-1704 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 90 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 26 work-hours x $85 per hour              $0  Up to $2,210.........  Up to $198,900.
 = Up to $2,210.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition action 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 this on-condition action:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
2 work-hours x $85 per hour = $170....            $500             $670
------------------------------------------------------------------------

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

[[Page 57797]]

under the criteria of the Regulatory Flexibility Act.

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.): Docket No. FAA-2024-1704; 
Project Identifier MCAI-2023-01204-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by August 30, 2024.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Embraer S.A. (Type Certificate previously 
held by Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A.) 
Model ERJ 190-100 IGW, -100 LR, -100 STD, -200 IGW, -200 LR, and -
200 STD airplanes, certificated in any category, as identified in 
Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD 
2023-11-02, effective November 21, 2023 (ANAC AD 2023-11-02).

(d) Subject

(e) Unsafe Condition

    This AD was prompted by a manufacturing quality escape 
concerning certain overheat detection system (ODS) sensing elements. 
The FAA is issuing this AD to address defective sensing elements. 
The unsafe condition, if not addressed, could result in a sensing 
element not being able to detect a thermal bleed leak, which is a 
latent failure, and, depending on the affected area, may start an 
ignition source in the fuel tank, which could damage some electronic 
boxes and expose the wing structure to high temperature gradients 
and unexpected thermal loads, which could result in reduced 
structural integrity of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Except as specified in paragraphs (h) and (i) of this AD: Comply 
with all required actions and compliance times specified in, and in 
accordance with, ANAC AD 2023-11-02.

(h) Exceptions to ANAC AD 2023-11-02

    (1) Where ANAC AD 2023-11-02 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) Where paragraph (b)(1) of ANAC AD 2023-11-02 specifies 
``Within 5,000 Flight Hours (FH) or 24 months,'' for this AD, 
replace that text with ``Within 7,500 Flight Hours (FH) or 36 
months.''
    (3) Where paragraphs (c)(1), (d)(1), (e)(1), (f)(1), and (g)(1) 
of ANAC AD 2023-11-02 specify ``Within 5,000 FH or 24 months,'' for 
this AD, replace that text with ``Within 7,500 FH or 36 months.''
    (4) Where paragraphs (b)(1), (c)(1), (d)(1), (e)(1), (f)(1), and 
(g)(1) of ANAC AD 2023-11-02 specify to inspect ODS sensing elements 
at various locations, this AD requires adding ``in accordance with 
Embraer Service Bulletin 190-36-0027, Revision 02, dated September 
5, 2023; or later revisions approved by ANAC.''
    (5) Where paragraphs (b) through (h) of ANAC AD 2023-11-02 
specify on-condition actions based on the results of the ODS sensing 
element inspections required by paragraphs (b)(1), (c)(1), (d)(1), 
(e)(1), (f)(1), and(g)(1) of ANAC AD 2023-11-02, this AD requires 
performing all applicable on-condition actions before further flight 
after each inspection.
    (6) This AD does not adopt paragraph (k) of ANAC AD 2023-11-02.
    (7) Where paragraph (l) of ANAC AD 2023-11-02 specifies ``Record 
compliance with this [ANAC] AD in the applicable maintenance log 
book,'' for this AD, record compliance with this FAA AD.

(i) No Return of Parts Requirement

    Although the service information referenced in ANAC AD 2023-11-
02 specifies to send removed parts to the manufacturer, this AD does 
not include that requirement.

(j) Special Flight Permit

    Special flight permits, as described in 14 CFR 21.197 and 
21.199, are not allowed.

(k) Additional AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Validation Branch, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or responsible Flight Standards Office, as 
appropriate. If sending information directly to the manager of the 
International Validation Branch, mail it to the address identified 
in paragraph (l)(1) of this AD. Information may be emailed to: [email protected]. Before using any approved AMOC, notify 
your appropriate principal inspector, or lacking a principal 
inspector, the manager of the responsible Flight Standards Office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, International 
Validation Branch, FAA; or ANAC; or ANAC's authorized Designee. If 
approved by the ANAC Designee, the approval must include the 
Designee's authorized signature.
    (3) Required for Compliance (RC): Except as required by 
paragraphs (i) and (k)(2) of this AD, if any service information 
referenced in ANAC AD 2023-11-02 contains steps in the 
Accomplishment Instructions or figures that are labeled as RC, the 
instructions in RC steps, including subparagraphs under an RC step 
and any figures identified in an RC step, must be done to comply 
with this AD; any steps including substeps under those steps, that 
are not identified as RC are recommended. The instructions in steps, 
including substeps under those steps, not identified as RC may be 
deviated from using accepted methods in accordance with the 
operator's maintenance or inspection program without obtaining 
approval of an AMOC, provided the instructions identified as RC can 
be done and the airplane can be put back in an airworthy condition. 
Any substitutions or changes to instructions identified as RC 
require approval of an AMOC. If a step or substep is labeled ``RC 
Exempt,'' then the RC requirement is removed from that step or 
substep.
