[[Page 21846]]

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2006-20-
08, which applied to all Embraer S.A. Model EMB-145, -145ER, -145MR, -
145LR, -145XR, -145MP, and -145EP airplanes. AD 2006-20-08 required 
repetitive inspections to detect cracking or failure of the rod ends 
and fittings of the aileron power control actuator (PCA), and 
corrective actions if necessary, and provided an optional terminating 
action. This AD was prompted by a determination that there was an error 
in identifying a maintenance task number. This AD continues to require 
the actions in AD 2006-20-08 and corrects an error in a task number, as 
specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil 
(ANAC) AD, which is incorporated by reference. The FAA is issuing this 
AD to address the unsafe condition on these products.

DATES: This AD is effective June 26, 2025.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 26, 
2025.

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2025-0010; or in person at Docket Operations between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD 
docket contains this final rule, the mandatory continuing airworthiness 
information (MCAI), any comments received, and other information. The

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2006-20-08, Amendment 39-14777 (71 FR 
58487, October 4, 2006) (AD 2006-20-08). AD 2006-20-08 applied to all 
Embraer Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -
145EP airplanes. AD 2006-20-08 required repetitive inspections to 
detect cracking or failure/breaking of the rod ends and fittings of the 
aileron PCA, and corrective actions if necessary, and provided an 
optional terminating action for the requirements. The FAA issued AD 
2006-20-08 to detect and correct cracking or breaking of the rod ends 
and connecting fittings of the aileron PCA, which could result in 
reduced controllability of the airplane.
    The NPRM published in the Federal Register on January 31, 2025 (90 
FR 8684). The NPRM was prompted by AD 1999-02-01R7, effective May 6, 
2024; as corrected October 11, 2024 (ANAC AD 1999-02-01R7) (also 
referred to as the MCAI), issued by ANAC, which is the aviation 
authority for Brazil. The MCAI states that after ANAC AD 1999-02-01R6 
was issued it was identified that the visual inspection task number 
referenced on requirement (c) of that AD (AMM TASK 27-12-01-212-002-
A00, ``Aileron PCA Rod Ends/Fitting, Lugs for Integrity and General 
Condition'') was incorrect. ANAC AD 1999-02-01R7 was issued to replace 
the task reference to MRB-145/1150 TASK 27-12-01-212-002-A05. For 
airplanes identified in paragraph (c) of ANAC AD 1999-02-01R7, 
accomplishing repetitive inspections as specified in MRB-145/1150 TASK 
27-12-01-212-002-A05 are necessary to address the unsafe condition.
    In the NPRM, the FAA proposed to continue to require the actions in 
AD 2006-20-08 and correct an error in a task number, as specified in 
ANAC AD 1999-02-01R7. The FAA is issuing this AD to address cracking or 
breaking of the rod ends and connecting fittings of the aileron PCA, 
which could result in reduced controllability of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2025-0010.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from the Air Line Pilots Association, 
International (ALPA) who supported the NPRM without change.

Conclusion

    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 
referenced above. The FAA reviewed the relevant data, considered the 
comment 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, 
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 1999-02-01R7 specifies procedures for repetitive 
inspections to detect cracking and failure of the rod ends and PCA 
fittings of the aileron PCA and corrective actions if necessary, and 
provides an optional terminating action. Corrective actions include 
replacing cracked and failed rod ends and PCA 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 will affect 272 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

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

    This airworthiness directive (AD) is effective June 26, 2025.

(b) Affected ADs

    This AD replaces AD 2006-20-08, Amendment 39-14777 (71 FR 58487, 
October 4, 2006) (AD 2006-20-08).

(c) Applicability

    This AD applies to all Embraer S.A. (Type Certificate previously 
held by Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A.;
