SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Embraer S.A.
Model ERJ 190-100 ECJ airplanes. The NPRM was published in the Federal
Register on February 25, 2026 (91 FR 9193). The NPRM was prompted by AD
2024-07-01, effective July 31, 2024 (ANAC AD 2024-07-01) (also referred
to as the MCAI), issued by ANAC, which is the aviation authority for
Brazil. The MCAI states that a quality escape occurred during
manufacturing concerning certain ODS sensing elements produced before
January 31, 2021. A defective sensing element may not be able to detect
a thermal bleed leak, which is a latent failure. This condition, if not
addressed, could lead to an undetected thermal bleed leak that could
start an ignition source in the fuel tank, damaging some electronic
boxes and exposing the wing structure to high temperature gradients and
unexpected thermal loads.
In the NPRM, the FAA proposed to require a detailed inspection of
certain ODS sensing elements of the airplane bleed lines and
replacement, if necessary, as specified in ANAC AD 2024-07-01. The NPRM
also proposed to prohibit the installation of affected parts, as
specified in ANAC AD 2024-07-01. The FAA is issuing this AD to address
the unsafe condition on these products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2026-1340.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from the Air Line Pilots Association,
International (ALPA) who supported the NPRM without change.
Clarification of Exception in Paragraph (h)(2) of This AD
The FAA revised paragraph (h)(2) of this AD to clarify the text in
ANAC AD 2024-07-01 that must be replaced.
Conclusion
These products have been approved by the civil aviation authority
of another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, that authority has notified the FAA of the unsafe condition
described in the MCAI referenced above. The FAA reviewed the relevant
data, considered any comments received, and determined that air safety
requires adopting this AD as proposed. Accordingly, the FAA is issuing
this AD to address the unsafe condition on these products. Except for
minor editorial changes, and any other changes described previously,
this AD is adopted as proposed in the NPRM. None of the changes will
increase the economic burden on any operator.
Material Incorporated by Reference Under 1 CFR Part 51
ANAC AD 2024-07-01 specifies procedures for a detailed inspection
of certain ODS sensing elements of the airplane bleed lines and
replacement, if necessary. ANAC AD 2024-07-01 also 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 the ADDRESSES section.
Costs of Compliance
The FAA estimates that this AD affects 8 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
[[Page 30200]]
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
108 work-hours x $85 per hour = $9,180....................... $0 $9,180 $73,440
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data on which to base a cost
estimate for the on-condition actions specified in this AD.
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,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will 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 Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 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:
2026-10-01 Embraer S.A. (Type Certificate Previously Held by
Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A.; Embraer
S.A.): Amendment 39-23341; Docket No. FAA-2026-1340; Project
Identifier MCAI-2024-00430-T.
(a) Effective Date
This airworthiness directive (AD) is effective June 26, 2026.
(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.;
Embraer S.A.) Model ERJ 190-100 ECJ airplanes, certificated in any
category, as identified in Ag[ecirc]ncia Nacional de

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, ANAC AD 2024-07-01.
(h) Exceptions to ANAC AD 2024-07-01
(1) Where ANAC AD 2024-07-01 refers to its effective date, this
AD requires using the effective date of this AD.
(2) Where paragraphs (b)(1) and (c)(1) of ANAC AD 2024-07-01
specify to inspect the ODS sensing elements of various ``areas of
the airplane'', this AD requires replacing that text with ``areas of
the airplane in accordance with Embraer Service Bulletin 190LIN-36-
0013, Revision 03, dated April 20, 2024; or later revisions approved
by ANAC''.
(3) Where paragraphs (b) and (c) of ANAC AD 2024-07-01 specify
on-condition actions based on the results of the ODS sensing element
inspections required by paragraphs (b)(1) and (c)(1) of ANAC AD
2024-07-01, this AD requires performing all applicable on-condition
actions before further flight after each inspection.
(4) This AD does not adopt paragraph (f) of ANAC AD 2024-07-01.
(i) Additional AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, AIR-
520, Continued Operational Safety 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 Continued Operational Safety Branch, send it to the attention of
the person identified in paragraph (j) of this AD and email to:
<a href="/cdn-cgi/l/email-protection#94d5d9dbd7d4f2f5f5baf3fbe2"><span class="__cf_email__" data-cfemail="1d5c50525e5d7b7c7c337a726b">[email protected]</span></a>. 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, AIR-520,
Continued Operational Safety 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
paragraph (i)(2) of this AD, if any material 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
[[Page 30201]]
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.
