SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2020-12-12, Amendment 39-19921 (85 FR
41175, July 9, 2020) (AD 2020-12-12). AD 2020-12-12 applied to all
Embraer S.A. Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 LR,
-200 SU, -200 STD, and -200 LL airplanes; and Model ERJ 190-100 STD, -
100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes.
AD 2020-12-12 required repetitive detailed inspections for cracking of
the engine inboard and outboard engine pylon lower link lugs, and
repair if necessary. The FAA issued AD 2020-12-12 to address cracking
of the engine pylon lower link lugs.
The NPRM was published in the Federal Register on February 7, 2025
(90 FR 9129). The NPRM was prompted by AD 2020-01-02R3, effective
October 17, 2024; corrected October 15, 2024 (ANAC AD 2020-01-02R3)
(also referred to as the MCAI), issued by ANAC, which is the aviation
authority for Brazil. The MCAI states that optional terminating actions
to the repetitive inspections have been included. ANAC AD 2020-01-02R2,
effective July 26, 2023, stated the compliance intervals were reduced.
In the NPRM, the FAA proposed to continue to require the actions in
AD 2020-12-12, with revised compliance times, as specified in ANAC AD
2020-01-02R3. The FAA is issuing this AD to address cracks on the left-
hand (LH) and right-hand (RH) sides of engine pylon inboard lower link
lugs. The unsafe condition, if not addressed, could cause the loss of
engine pylon integrity, which could result in engine separation from
the wing, loss of airplane controllability, and possible injury to
persons on ground.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2025-0022.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from Air Line Pilots Association,
International (ALPA), and an individual commenter who supported the
NPRM without change.
The FAA received additional comments from two commenters, including
Envoy Air and Horizon Air. The following presents the comments received
on the NPRM and the FAA's response to each comment.
[[Page 34169]]
Request To Clarify Terminating Action
Envoy Air requested clarification about whether the terminating
action in paragraph (d) of ANAC AD 2020-01-02R3 applies to the initial
inspection specified in paragraph (b) or just the repetitive
inspections specified in paragraph (c), as stated in ANAC AD 2020-01-
02R3. The commenter pointed out that the FAA approved an alternative
method of compliance (AMOC) (510-24-00070, dated May 14, 2024) with the
inspections in paragraph (g) of AD 2020-12-12, but the AMOC does not
differentiate between initial or repetitive inspections.
The FAA agrees to clarify. This AD provides terminating action only
for the repetitive inspections, as does ANAC AD 2020-01-02R3. ANAC AD
2020-01-02R3 contains an implementation plan for airplanes near or past
the threshold of the initial inspection that might differ from the
maintenance review board (MRB) tasks. Once the initial inspection is
accomplished, the MRB task can be used for compliance to the repetitive
inspection requirement. No change is necessary to this AD in this
regard.
Request To Clarify Versions of ANAC AD
Horizon Air requested that the FAA revise paragraphs (g) through
(k) of the proposed AD to include the corrected date of ANAC AD 2020-
01-02R3. Horizon Air noted that paragraphs (c) and (m) of the proposed
AD include both the effective and corrected dates and asserted that
repeating this information in the remaining paragraphs would improve
clarity.
The FAA agrees with the intent to reference the corrected version
of ANAC AD 2020-01-02R3 in this AD, as it is the only effective version
available on the foreign civil aviation authority's (FCAA) website.
However, the FAA does not agree with revising all instances of ``ANAC
AD 2020-01-02R3'' to include its effective and correction dates.
Paragraph (c) of this AD establishes the legal definition, including
effective and correction dates, to be ANAC AD 2020-01-02R3, effective
October 17, 2024; corrected October 15, 2024. Therefore, all subsequent
references to ANAC AD 2020-01-02R3 throughout the regulatory text of
this AD are understood to refer to the version identified in paragraph
(c) of this AD. No change has been made in this regard.
Additional Changes Made to This AD
The FAA has revised paragraph (h)(2) of this AD to match the
wording used in ANAC AD 2020-01-02R3 when referring to revision 1 of
ANAC AD 2020-01-02. The FAA intended to match ANACs wording and has
revised this AD for clarity.
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 this product. 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
The FAA reviewed ANAC AD 2020-01-02R3, which specifies procedures
for repetitive detailed inspections, special detailed inspections, and
repair, as applicable, of the LH and RH engine inboard and outboard
pylon lower link lugs. ANAC AD 2020-01-02R3 also includes an optional
terminating action for the repetitive inspections, which consists of
revising the maintenance or inspection program, as applicable, to
incorporate airworthiness limitations for pylon lower link fittings.
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 659 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspections.............................. 3 work-hour x $85 per hour $0 $255 $168,045
= $255.
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data that would enable the
agency to provide cost estimates for the on-condition repair specified
in this AD.
For the optional terminating action, the FAA has determined that
revising the existing maintenance or inspection program takes an
average of 90 work-hours per operator, although the agency recognizes
that this number may vary from operator to operator. Since operators
incorporate maintenance or inspection program changes for their
affected fleet(s), the FAA has determined that a per-operator estimate
is more accurate than a per-airplane estimate. Therefore, if the
optional terminating action is done, the agency estimates the average
total cost per operator would be $7,650 (90 work-hours x $85 per work-
hour).
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.
[[Page 34170]]
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.
