Airworthiness Directives; Embraer 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. (Embraer) Model EMB-505 airplanes. This 
proposed AD was prompted by an occurrence of corrosion on the clutch 
retaining bolt of the aileron autopilot servo mount. This proposed AD 
would require repetitively replacing the clutch retaining bolt and 
washer of the aileron autopilot servo mount, 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.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under ADDRESSES. Include ``Docket No. FAA-2023-1504; Project Identifier 
MCAI-2023-00473-A'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the proposal, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
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 Jim 
Rutherford, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 
410, Westbury, NY 11590. Any commentary that the FAA receives which is 
not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

Background

    The ANAC, which is the aviation authority for Brazil, has issued 
ANAC AD 2023-02-01R1, effective March 14, 2023 (referred to after this 
as ``the MCAI''), to correct an unsafe condition on certain serial-
numbered Embraer Model EMB-505 airplanes. The MCAI states that an 
occurrence of corrosion was found on the clutch retaining bolt of the 
aileron autopilot servo mount. This condition could result in failure 
of the clutch retaining bolt of the aileron autopilot servo mount, 
which could disengage the clutch from the drive pin and jam the aileron 
controls, resulting in reduced controllability of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-1504.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed ANAC AD 2023-02-01R1, which specifies procedures 
for replacing the clutch retaining bolt and washer of the aileron 
autopilot servo mount.
    This service information 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

    These products have been approved by the 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, it has notified the FAA of the unsafe condition described in 
the MCAI described above. The FAA is issuing this NPRM after 
determining that the unsafe condition described previously is likely to 
exist or develop on 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 2023-02-01R1 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 2023-02-01R1 by reference in the 
FAA final rule. This proposed AD would, therefore, require compliance 
with ANAC AD 2023-02-01R1 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-
02-01R1 for compliance will be available at regulations.gov under 
Docket No. FAA-2023-1504 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 505 airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

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

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, all of the costs associated 
with the initial bolt and washer replacement may be covered under 
warranty.

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.

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:

PART 39--AIRWORTHINESS DIRECTIVES

unless already done.

(g) Required Actions

    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 2023-02-01R1.

(h) Exceptions to ANAC AD 2023-02-01R1

    (1) Where ANAC AD 2023-02-01R1 refers to February 6, 2023, the 
effective date of ANAC AD 2023-02-01, this AD requires using the 
effective date of this AD.
    (2) Where ANAC AD 2023-02-01R1 requires replacing a part with a 
new part, for the purposes of this AD, ``new'' means zero flight 
hours.

specifies ``If the airplane operation age and/or the flight hours 
criteria change before the SB accomplishment, the most restrictive 
criteria must be obeyed,'' this AD requires complying with the most 
restrictive criteria in Table 01 of ANAC AD 2023-02-01R1.
    (4) This AD does not adopt paragraph (d) of ANAC AD 2023-02-
01R1.

(i) No Reporting Requirement

    Although the service information referenced in ANAC AD 2023-02-
01R1 specifies to submit certain information to the manufacturer, 
this AD does not include that requirement.

(j) 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,
