Airworthiness Directives; Embraer S.A. Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Embraer S.A. (Embraer) Model EMB-505 airplanes. This AD was
prompted by the possibility that some airplanes may have invalid
horizontal stabilizer (HS) backlash test results due to the use of
incorrect procedures. This AD requires inspecting the airplane's left-
hand (LH) and right-hand (RH) HS backlash and replacement, as
applicable, of certain hinge point and pitch trim actuator attachment
parts and the pitch trim actuator. The FAA is issuing this AD to
address the unsafe condition on these products.
DATES: This AD is effective July 6, 2026.
The Director of the Federal Register approved the incorporation by
reference
[[Page 32327]]
of a certain publication listed in this AD as of July 6, 2026.

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 Model
EMB-505 airplanes. The NPRM was published in the Federal Register on
November 18, 2025 (90 FR 51607). The NPRM was prompted by ANAC AD 2025-
04-01, effective April 15, 2025 (ANAC AD 2025-04-01) (also referred to
as the MCAI), issued by ANAC, which is the aviation authority for
Brazil. The MCAI states that there is a possibility of some airplanes
having invalid HS backlash test results due to the use of incorrect
test procedures. The excessive backlash may result in an aeroelastic
phenomenon exposing the surrounding structure and systems to
unacceptable vibration levels and reduced controllability of the
airplane.
In the NPRM, the FAA proposed to require inspecting the airplane's
LH and RH HS backlash and replacing, as applicable, the LH and RH hinge
point attachment parts, the LH or RH pitch trim actuator rod-end
attachment parts, and the pitch trim actuator. 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-2025-3993.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from the Citizens Rulemaking Alliance.
The following presents the comments received on the NPRM and the FAA's
response to each comment.
Request To Justify Forgoing Notice and Comment
The Citizens Rulemaking Alliance requested that the FAA provide its
justification for finding good cause to bypass notice and comment
procedures, reopen the comment period for at least 30 days, and delay
enforcement of non-time critical provisions pending comment unless the
risk analysis demonstrates a truly imminent hazard. The commenter
asserted the FAA has not adequately justified use of the good cause
exemption to bypass notice and comment and the 30-day delayed effective
date.
The FAA notes the comment was submitted in response to an NPRM for
which the FAA provided a 45-day comment period. This final rule is
effective 35 days after its publication in the Federal Register.
Therefore, no change to this AD is necessary.
Request To Make Incorporation by Reference (IBR) Materials Reasonably
Available
The Citizens Rulemaking Alliance stated that the FAA's current
practices for IBR frequently fail to meet the legal and regulatory
standards for reasonable availability. The commenter called on the FAA
to guarantee that all IBR materials are easily and freely accessible to
the public and affected parties for the duration of the comment period
and to reopen the comment period for at least 30 days to accommodate
this access. Furthermore, the commenter requested that, if the
manufacturer will not consent to open posting of the IBR materials in
the docket, the FAA should either obtain permission to post the
materials or provide a detailed technical summary sufficient for
meaningful comment.
The FAA notes that ANAC AD 2025-04-01, which is incorporated by
reference in this AD, is available to the public on the ANAC website at
sistemas.anac.gov.br/certificacao/DA/DAE.asp, as explained in the
preamble and regulatory text of the NPRM. This material was also posted
in the AD docket upon publication of the NPRM. Therefore, the FAA did
not change this AD as a result of this comment.
Request To Consider Impact on Small Entities
The Citizens Rulemaking Alliance requested that the FAA either
provide the factual basis for its Regulatory Flexibility Act (RFA)
certification that the AD will not have a significant economic impact
on a substantial number of small entities or prepare an initial
regulatory flexibility analysis and consider less burdensome
alternatives for small operators. The commenter stated that the FAA
should also reopen the comment period to allow comment on that
analysis.
FAA has considered the AD's impact on small businesses and provides
the following factual basis for its RFA certification.
The Regulatory Flexibility Act of 1980, Public Law 96-354, 94 Stat.
1164 (5 U.S.C. 601-612), as amended by the Small Business Regulatory
Enforcement Fairness Act of 1996 (Pub. L. 104-121, 110 Stat. 857, Mar.
29, 1996) and the Small Business Jobs Act of 2010 (Pub. L. 111-240, 124
Stat. 2504, Sept. 27, 2010), requires Federal agencies to consider the
effects of the regulatory action on small business and other small
entities and to minimize any significant economic impact. The term
``small entities'' comprises small businesses and not-for-profit
organizations that are independently owned and operated and are not
dominant in their fields, and governmental jurisdictions with
populations of less than 50,000.
Small Entities to Which This AD Applies
The FAA used the definition of small entities in the RFA for this
analysis. The RFA defines small entities as small businesses, small
governmental jurisdictions, or small organizations. In 5 U.S.C. 601(3),
the RFA defines ``small business'' to have the same meaning as ``small
business concern'' under section 3 of the Small Business Act. The Small
Business Act authorizes the Small Business Administration (SBA) to
define ``small business'' by issuing regulations.
[[Page 32328]]
The SBA (2023) has established size standards for various types of
economic activities, or industries, under the North American Industry
Classification System (NAICS). These size standards generally define
small businesses based on the number of employees or annual receipts.
The SBA definition of a small business applies to the parent company
and all affiliates as a single entity. The following table provides the
SBA size standards for all industries with at least one entity impacted
by this AD. Note that the FAA does not have entity data on 13 of the 41
affected airplanes, and those airplanes with missing entity data are
excluded from this analysis.

------------------------------------------------------------------------
To identify small entities, the FAA first identified the primary
NAICS of the entity or parent company, and then used data from
different sources (e.g., company annual reports, Bureau of
Transportation Statistics) to determine whether the entity meets the
applicable size standard. The FAA provides the estimated number of
small entities affected by this AD:

Projected Reporting, Recordkeeping, and Other Compliance Requirements
FAA estimates affected entities will incur an inspection cost of
$1,360. Based upon the results of the inspection, operators could incur
up to five conditional repair costs. If an operator were to incur all
repair and inspection costs, FAA estimates each operator would incur
$14,950 per airplane. However, according to the manufacturer, all of
the costs of this AD may be covered under warranty, thereby reducing
the cost impact on affected entities. The FAA analyzes the cost of
inspections and all repair costs over the two-year analysis period for
each small entity. The following table provides the estimated
compliance costs at a 7 percent annualized discount rate by each NAICS
industry.

Significant Alternatives Considered
The FAA evaluated the alternative of not promulgating this AD but
ultimately deemed that this alternative would create a significant
safety hazard. The FAA is issuing this AD to address the unsafe
condition for certain Embraer Model EMB-505 airplanes, ensuring a level
of safety that the alternative of no action could not provide.
RFA Conclusions
Based on average compliance costs, the FAA has determined that the
financial impacts of this AD are not disproportionate to small
entities. The FAA did not change this AD as a result of this comment.
Request To Comply With the Paperwork Reduction Act (PRA)
The Citizens Rulemaking Alliance requested that the FAA revise the
proposed AD to comply with the PRA if reporting is required or remove
any reporting provisions until PRA requirements are satisfied.
The FAA notes that paragraph (i) of this AD specifies that this AD
does not require reporting. If an AD were to require reporting, the
preamble of the AD would include a paragraph titled ``Paperwork
Reduction Act'' that would provide the applicable OMB control number,
required PRA statements, and the estimated time to collect the required
information (burden). Any costs associated with the reporting
requirement would be included in the Costs of Compliance section in the
preamble of the AD. Therefore, the FAA did not change this AD as a
result of this comment.
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. This AD is
adopted as proposed in the NPRM.
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed ANAC AD 2025-04-01, which specifies procedures for
inspecting the LH and RH HS backlash for correct values, and replacing,
as applicable, the LH and RH hinge point attachment parts, the LH or RH
pitch trim actuator rod-end attachment parts, and the pitch trim
actuator. 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.
Differences Between This AD and the MCAI
The material specified in ANAC AD 2025-04-01 allows the use of
alternative or similar parts in place of the ones specified in the
kits, provided these alternative or similar parts are approved by
Embraer, but this AD requires approval from either the Manager,
International Validation Branch, FAA; ANAC; or ANAC's authorized
Designee. If approved by the ANAC Designee, the approval must include
the Designee's authorized signature.
Costs of Compliance
The FAA estimates that this AD affects 41 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------
High-Case Cost \3\ 14,950 612,950
----------------------------------------------------------------------------------------------------------------
\1\ FAA estimated operators will incur $85 in costs per labor hour, which is the weighted average fiscal year
(FY) 2026 fully loaded wage of an aircraft mechanic ($69.85) working 60% of the labor hours and a general and
operations manager ($108.15) working 40% of the labor hours. The FAA estimated these wages by taking the
average of the FY 2024 Bureau of Labor Statistics (BLS) air transportation industry average wage for aircraft
mechanics and general and operations managers (See: Occupational Employment and Wage Statistics Query System,
BLS (May 2024), data.bls.gov/oes/); multiplying each wage by a fringe benefit factor of 1.42 (See: Employer
Cost for Employee Compensation--December 2024, BLS (2024), bls.gov/news.release/archives/ecec_03142025.pdf);
and adjusting these 2024 wages to 2026 dollars using an implicit Gross Domestic Product (GDP) Price Deflator
of 2.8% (See: Gross Domestic Product: Implicit Price Deflator, FRED (2026) fred.stlouisfed.org/series/GDPDEF).
\2\ The low-case cost assumes each airplane incurs only inspection costs.
\3\ The high-case cost assumes each airplane incurs inspection and all conditional repair costs.
Over a two-year analysis period, the FAA estimates operators will
incur an inspection cost of $1,360. Based upon the results of the
inspection, operators could incur five conditional repair costs. If an
operator were to incur all inspection and repair costs, the FAA
estimates each operator would incur $14,950 per airplane. The FAA
cannot estimate the number of conditional repairs each operator would
need to undertake, but the cost of an inspection ($1,360) and the cost
of an inspection and all conditional repairs ($14,950) represent the
low-case and high-case costs per affected airplane.
FAA recognizes that operators might incur additional costs, such as
airplane downtime. However, FAA anticipates this AD will not trigger
any downtime costs because the requirements of this AD can be performed
during regularly scheduled maintenance.
The FAA uses a two-year analysis period for estimating the
annualized costs of this AD. Upon this AD's promulgation, all Group 1
airplanes must be inspected within 12 months or 750 flight hours, and
all Group 2 airplanes must be inspected within 24 months or 1,000
flight hours. In this analysis, FAA assumes all Group 1 costs will be
incurred in year 1, and all Group 2 costs will be incurred in year 2.
The following tables display the annual AD compliance costs and
summarize the AD's quantified and unquantified benefits and costs.

The FAA has included all known costs in its cost estimates.
According to the manufacturer, however, all of the costs of this 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
[[Page 32331]]
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.
