SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2007–19–09R1, Amendment 39–16322 (75 FR 30687, June 2, 2010), (‘‘AD 2007–19–09R1’’). AD 2007–19–09R1 applied to the specified products. The NPRM published in the Federal Register on December 24, 2013 (78 FR 77614). The E:\FR\FM\10APR1.SGM 10APR1 Federal Register / Vol. 79, No. 69 / Thursday, April 10, 2014 / Rules and Regulations NPRM proposed to continue to require HMU replacement. That NPRM also proposed to require reduction of the compliance interval; and inclusion of the power turbine C2 cycle consumption rate when determining compliance times. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 77614, December 24, 2013). 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 264 engines installed on airplanes of U.S. registry. We also estimate that it will take about one hour per engine to comply with this AD. The average labor rate is $85 per hour. Required parts cost about $5,000 per engine. Based on these figures, we estimate the cost of this AD to U.S. operators is $1,342,440. (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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

Airworthiness Directives; Turbomeca S.A. Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding airworthiness directive (AD) 2007-19-09R1 
for all Turbomeca S.A. Arriel 2B1 turboshaft engines that do not have 
modification TU157 incorporated. AD 2007-19-09R1 required replacement 
of the hydromechanical metering unit (HMU) with a serviceable HMU. This 
AD requires HMU replacement; reduction of the compliance interval; and 
inclusion of the power turbine C2 cycle consumption rate when 
determining compliance times. This AD was prompted by reports of 
ruptures on HMU constant delta pressure valves that have less than 
2,000 hours in service. We are issuing this AD to prevent failure of 
the HMU, which could lead to damage to the engine, and damage to the 
aircraft.

DATES: This AD is effective May 15, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2007-19-09R1, Amendment 39-16322 (75 FR 30687, 
June 2, 2010), (``AD 2007-19-09R1''). AD 2007-19-09R1 applied to the 
specified products. The NPRM published in the Federal Register on 
December 24, 2013 (78 FR 77614). The

[[Page 19813]]

NPRM proposed to continue to require HMU replacement. That NPRM also 
proposed to require reduction of the compliance interval; and inclusion 
of the power turbine C2 cycle consumption rate when determining 
compliance times.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 77614, December 24, 
2013).

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 264 engines installed on airplanes 
of U.S. registry. We also estimate that it will take about one hour per 
engine to comply with this AD. The average labor rate is $85 per hour. 
Required parts cost about $5,000 per engine. Based on these figures, we 
estimate the cost of this AD to U.S. operators is $1,342,440.

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.

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends part 39 of the Federal Aviation
