14 CFR Part 39

[Docket No. FAA-2020-0463; Product Identifier 2013-SW-041-AD; Amendment 
39-21246; AD 2015-17-01R1]
RIN 2120-AA64


Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; removal of airworthiness directive (AD).

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

SUMMARY: The FAA is removing AD 2015-17-01, which applied to certain 
Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, 
AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and 
AS355NP helicopters. AD 2015-17-01 required inspections of each tail 
rotor pitch horn assembly (pitch horn) for a crack, replacement of a 
cracked pitch horn, and a repetitive visual inspection of certain pitch 
horns. AD 2015-17-01 is no longer necessary because the cause of the 
unsafe condition has been removed from all affected helicopter models. 
Accordingly, the FAA is removing AD 2015-17-01.

DATES: This AD becomes effective September 11, 2020.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by removing AD 2015-17-01, Amendment 39-18234 (80 FR 50554, 
August 20, 2015) (``AD 2015-17-01''), that applied to certain Airbus 
Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, 
AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP 
helicopters. The NPRM published in the Federal Register on June 12, 
2020 (85 FR 35814). The NPRM was prompted by a determination that AD 
2015-17-01 is no longer necessary because the unsafe condition no 
longer exists on Model AS350 and AS355 helicopters. The NPRM proposed 
to remove AD 2015-17-01. The FAA is issuing this AD to remove AD 2015-
17-01.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA has considered the comment 
received. Mr. Warren LaBare indicated support for the NPRM.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. The FAA has determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    This AD adds no cost. This AD removes AD 2015-17-01 from 14 CFR 
part 39; therefore, operators are no longer required to show compliance 
with that AD.

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.

[[Page 56162]]

This regulation is within the scope of that authority.

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.
