We are adopting a new airworthiness directive (AD) for certain Turbomeca S.A. Arriel 1E2 turboshaft engines. This AD requires removing the tachometer box on affected engines. This AD was prompted by reports of uncommanded in-flight shutdowns (IFSDs). We are issuing this AD to prevent failure of the tachometer box, which could lead to failure of the engine, IFSD, and loss of control of the helicopter.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to the specified products. The 
NPRM was published in the Federal Register on November 24, 2015 (80 FR 
73147). The NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    There have been reports of Arriel 1E2 engines having experienced 
an uncommanded in-flight shut-down (IFSD) due to an untimely 
activation of the tachometer box shut-off system which was activated 
by the power turbine monitoring function of the tachometer box.
    This condition, if not corrected, could potentially lead to 
further cases of IFSD, possibly resulting in a forced landing.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 73147, November 24, 
2015).

Conclusion

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

Related Service Information

    Turbomeca S.A. has issued Mandatory Service Bulletin No. 292 77 
0844, Version B, dated July 6, 2015. The service information describes 
procedures for removing pre-TU 369 tachometer boxes.

Costs of Compliance

    We estimate that this AD affects 200 engines installed on 
helicopters of U.S. registry. We also estimate that it will take about 
3 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 $51,000.

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

    We determined that 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 this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:
