Airworthiness Directives; Turbomeca S.A. Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding airworthiness directive (AD) 2007-10-07 for
all Turbomeca S.A. Arriel 2B, 2B1, and 2B1A turboshaft engines. AD
2007-10-07 required an inspection of the splines of the coupling
assembly and the hydro-mechanical metering unit (HMU) drive gear shaft
for wear. This AD requires the same inspection and expands the affected
population. This AD also removes Arriel 2B1A engines from the
applicability. We are issuing this AD to prevent failure of the HMU
drive gear shaft, which could lead to damage to the engine and damage
to the airplane.

DATES: This AD is effective August 4, 2014.
    The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of August 4,
2014.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2007-10-07, Amendment 39-15048 (72 FR 26711,
May 11, 2007), (``AD 2007-10-07''). AD 2007-10-07 applied to the
specified products. The NPRM published in the Federal Register on
February 21, 2014 (79 FR 9868). The NPRM proposed to require the same
inspection as AD 2007-10-07 and expand the affected population. The
NPRM also proposed to remove Arriel 2B1A engines from the
applicability.

Comments

    We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (79 FR 9868, February 21,
2014).

Conclusion

    We reviewed the available data and determined that air safety and
the public interest require adopting this AD as proposed.

Costs of Compliance

    We estimate that this AD affects 470 engines installed on aircraft
of U.S. registry. We also estimate that it will take about 2 hours per
engine to comply with this AD. The average labor rate is $85 per hour.
Based on these figures, we estimate the cost of this AD on U.S.
operators to be $79,900.

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.
    We are 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) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska to the extent
that it justifies making a regulatory distinction, and
    (4) 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.

14 CFR Part 71

[Docket No. FAA-2020-0642; Airspace Docket No. 19-AWP-98]
RIN 2120-AA66

Amendment of V-25, V-27, V-494, V-108, V-301, and T-257 in the
Vicinity of Santa Rosa, CA

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

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

SUMMARY: This action corrects a final rule published by the FAA in the
Federal Register on June 4, 2021 that amends VHF Omnidirectional Range
(VOR) Federal airways V-25, V-27, V-494, V-108, V-301, and United
States Area Navigation route (RNAV) T-257 in the vicinity of Santa
Rosa, CA. This action makes an editorial correction to include the
Mendocino VOR, which was inadvertently deleted from the legal
description for V-494. Amendments are due to the planned
decommissioning of the Santa Rosa, CA VOR/Distance Measuring Equipment
(DME) navigation aid (NAVAID) which provides navigation guidance for
portions of the affected airways. The Santa Rosa VOR/DME is being
decommissioned as part of the FAA's VOR Minimum Operational Network
(MON) program.

DATES: Effective date 0901 UTC, August 12, 2021. The Director of the
Federal Register approves this incorporation by reference action under
1 CFR part 51, subject to the annual revision of FAA Order 7400.11 and
publication of conforming amendments.

ADDRESSES: FAA Order 7400.11E, Airspace Designations and Reporting
Points, and subsequent amendments can be viewed online at https://www.faa.gov/air_traffic/publications/. For further information, you can

SUPPLEMENTARY INFORMATION:

History

    The FAA published a notice of proposed rulemaking for Docket No.
FAA-2020-0642 in the Federal Register (85 FR 47928; August 7, 2020) and
a final rule (86 FR 29946; June 4, 2021), amending VOR Federal airways
V-25, V-27, V-494, V-108, V-301, and RNAV route T-257 in the vicinity
of Santa Rosa, CA, due to the planned decommissioning of the Santa
Rosa, CA, VOR/DME NAVAID. Subsequent to the publication, it was
determined that Mendocino, CA, VOR was missing from the legal
description of V-494. This rule corrects that error by including
Mendocino, CA, VOR in its appropriate place in the V-494 legal
description. This is an editorial change only and does not alter the
alignment of the route as shown on aeronautical charts, and does not
affect the use of the route by aircraft.
    VOR Federal airways are published in paragraph 6010(a) of FAA Order
7400.11E dated July 21, 2020, and effective September 15, 2020, which
is incorporated by reference in 14 CFR 71.1. The VOR Federal airway
listed in this document will be subsequently published in the Order.

Availability and Summary of Documents for Incorporation by Reference

    This document amends FAA Order 7400.11E, Airspace Designations and
Reporting Points, dated July 21, 2020, and effective September 15,
2020. FAA Order 7400.11E is publicly available as listed in the
ADDRESSES section of this document. FAA Order 7400.11E lists Class A,
B, C, D, and E airspace areas, air traffic service routes, and
reporting points.
