Unsafe Condition
(e) Unsafe Condition
This AD was prompted by failed lockwires on the attachment of
the left-hand main landing gear (MLG) trunnion bearing to spar 2 on
a flight test airplane. These lockwires are designed to safety one
shear pin to the other, keeping the integrity of the assembly
through the torque applied to the shear pins. The FAA is issuing
this AD to address this condition, which could result in structure
vibration and possible rotation of the shear pins causing lockwire
failure and shear pin migration, which could collapse the MLG
structure during takeoff and landing operations.

Background
ANAC, which is the aviation authority for Brazil, has issued ANAC
AD 2022-04-02, effective May 3, 2022 (ANAC AD 2022-04-02) (also
referred to as the MCAI), to correct an unsafe condition for certain
Embraer S.A. Model ERJ 190-300 airplanes. The MCAI states that there
was an occurrence of failed lockwires, having part number (P/N) MS
20995C32, on the attachment of the left-hand MLG trunnion bearing to
spar 2 on a flight test airplane. These lockwires are designed to
safety one shear pin to the other, keeping the integrity of the
assembly through the torque applied to the shear pins. The structure
vibration could cause the rotation of the shear pins causing the
lockwire failure and the shear pin migration, which can collapse the
MLG structure during takeoff and landing operations. You may examine
the MCAI in the AD docket at regulations.gov under Docket No. FAA-2023-
0166.
Related Service Information Under 1 CFR Part 51
ANAC AD 2022-04-02 specifies procedures for inspecting for damage
of the left- and right-hand MLG trunnion bearing attaching parts,
replacing any damaged parts and torquing shear pins, having P/N 196-
32185-007 or P/N 196-32216-007, and modifying the MLG trunnion bearing
attaching parts to spars 2 and 3. 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.
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
described above. The FAA is issuing this AD after determining that the
unsafe condition described previously is likely to exist or develop on
other products of the same type design.
Requirements of This AD
This AD requires accomplishing the actions specified in ANAC AD
2022-04-02 described previously, except for any differences identified
as exceptions in the regulatory text of this 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,
ANAC AD 2022-04-02 is incorporated by reference in this AD. This AD
requires compliance with ANAC AD 2022-04-02 in its entirety through
that incorporation, except for any differences identified as exceptions
in the regulatory text of this AD. Service information required by ANAC
AD 2022-04-02 for compliance will be available at regulations.gov under
Docket No. FAA-2023-0166 after this AD is published.
FAA's Justification and Determination of the Effective Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and
comment procedures for rules when the agency, for ``good cause,'' finds
that those procedures are ``impracticable, unnecessary, or contrary to
the public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
There are currently no domestic operators of these products.
Accordingly, notice and opportunity for prior public comment are
unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the
forgoing reason(s), the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days.
Regulatory Flexibility Act (RFA)
The requirements of the RFA do not apply when an agency finds good
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and
comment. Because the FAA has determined that it has good cause to adopt
this rule without notice and comment, RFA analysis is not required.
Costs of Compliance
Currently, there are no affected U.S.-registered airplanes. If an
affected airplane is imported and placed on the U.S. Register in the
future, the FAA provides the following cost estimates to comply with
this AD:
Estimated Costs for Required Actions
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
69 work-hours x $85 per hour = $7,333 per kit.... Up to $20,531.
$5,865.
------------------------------------------------------------------------
[[Page 13308]]
According to the manufacturer, some or all of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected individuals. The FAA does not control warranty coverage for
affected individuals. As a result, the FAA has included all known costs
in the cost estimate.
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, and
(2) Will not affect intrastate aviation in Alaska.
