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 5, 2015 (80 FR 68475). The NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Several cases of torque conformation box (TCB) failures have been reported on engines incorporating mod TU34 or mod TU34A. Investigation concluded that these failures were caused by cracks on soldered joints of TCB resistors. This condition, if not corrected, could lead to limited power availability in a One Engine Inoperative (OEI) case, possibly resulting in reduced control of the helicopter. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (80 FR 68475, November 5, 2015). Conclusion We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed. mstockstill on DSK4VPTVN1PROD with RULES Related Service Information Under 1 CFR Part 51 Turbomeca S.A. has issued Mandatory Service Bulletin (MSB) No. 292 72 2860, Version A, dated July 15, 2015. The MSB describes procedures for checking TCB resistance values. This service information 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 of this final rule. VerDate Sep<11>2014 16:23 Feb 08, 2016 Jkt 238001 Costs of Compliance We estimate that this AD affects 300 engines installed on helicopters of U.S. registry. We estimate that it would take about 1 hour to perform an inspection. We also estimate that 20% of these engines would fail the inspection and require TCB removal, which would take about 1 hour. 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 $30,600. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. 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. § 39.13 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. (e) Actions and Compliance Comply with this AD within the compliance times specified, unless already done. (1) Within 600 engine flight hours (EFHs) or 6 months after the effective date of this AD, whichever occurs first, check the resistance values on the TCB. Use Accomplishment Instructions, paragraph 2.3.2 of Turbomeca S.A. Mandatory Service Bulletin 292 72 2860, Version A, dated July 15, 2015, to do the inspection. Repeat this inspection every 600 EFHs since last inspection. (2) Remove before further flight any TCB that fails the inspection required by paragraph (e)(1) of this AD.

Issued in Burlington, Massachusetts, on February 2, 2016. Colleen M. D’Alessandro, Manager, Engine & Propeller Directorate, Aircraft Certification Service. was prompted by a review of operational data that determined certain RR RB211–535E4–37 engines have been operated to a more severe flight profile than is consistent with the flight profile used to establish the cyclic life limits for the rotating parts. We are issuing this AD to prevent failure of life-limited rotating parts, uncontained parts release, damage to the engine, and damage to the airplane. Discussion This AD becomes effective March 15, 2016. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of March 15, 2016. A review of operational flight data has revealed that some RB211–535 engines may have been operated beyond the flight profile (FP) assumed by the operator when establishing the operational limits (life limits) within which the corresponding critical parts are allowed to remain installed. This condition, if not corrected, may lead to critical part failure, possibly resulting in release of high energy debris, damage to the aeroplane and/or injury to the occupants.

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 5, 2015 (80 FR 
68475). The NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    Several cases of torque conformation box (TCB) failures have 
been reported on engines incorporating mod TU34 or mod TU34A. 
Investigation concluded that these failures were caused by cracks on 
soldered joints of TCB resistors.
    This condition, if not corrected, could lead to limited power 
availability in a One Engine Inoperative (OEI) case, possibly 
resulting in reduced control of the helicopter.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 68475, November 5, 
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 Under 1 CFR Part 51

    Turbomeca S.A. has issued Mandatory Service Bulletin (MSB) No. 292 
72 2860, Version A, dated July 15, 2015. The MSB describes procedures 
for checking TCB resistance values. This service information 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 of this final rule.

Costs of Compliance

    We estimate that this AD affects 300 engines installed on 
helicopters of U.S. registry. We estimate that it would take about 1 
hour to perform an inspection. We also estimate that 20% of these 
engines would fail the inspection and require TCB removal, which would 
take about 1 hour. 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 
$30,600.

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
