DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2015–5539; Directorate Identifier 2015–NE–37–AD; Amendment 39– 18493; AD 2016–08–16] RIN 2120–AA64 Airworthiness Directives; Turbomeca S.A. Turboshaft Engines Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all Turbomeca S.A. Arriel 2E turboshaft engines. This AD requires removing the pre-TU 193 adjusted high-pressure/lowpressure pump and metering valve assembly and replacing it with a part that is eligible for installation. This AD also requires replacing the constant delta-pressure (delta-P) diaphragm of the fuel metering valve. This AD was prompted by reports of fuel flow nonconformities found during acceptance tests of Arriel 2E hydro-mechanical metering units (HMUs). We are issuing this AD to prevent failure of the deltaP diaphragm, which could result in an uncommanded in-flight shutdown and damage to the helicopter. DATES: This AD becomes effective May 25, 2016. ADDRESSES: For service information identified in this AD, contact Turbomeca S.A., 40220 Tarnos, France; phone: 33 (0)5 59 74 40 00; fax: 33 (0)5 59 74 45 15.

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 January 4, 2016 (81 FR 30). The NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Fuel flow non-conformities were found during reception tests of ARRIEL 2E Hydraulic Mechanical Metering Unit (HMU). Investigation and instrumented tests revealed instabilities on the additional check valve. These instabilities lead to hydraulic pulses. All HMU installed on ARRIEL 2E and 2N engines could present these instabilities. This condition, if not corrected, could lead to life reduction of the delta pressure valve diaphragm, and consequently, an uncommanded engine power increase, or an uncommanded in flight shutdown, possibly resulting in an emergency landing. You may obtain further information by examining the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2015– 5539.

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 (MSB) No. 292 73 2193, Version A, dated July 16, 2015. The MSB describes procedures for incorporating modification TU 193 and replacing the constant delta-P diaphragm of the fuel metering valve. Costs of Compliance We estimate that this AD affects 12 engines installed on helicopters 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. Required parts cost about $13,400 per engine. Based on these figures, we estimate the cost of this AD on U.S. operators to be $162,840. 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 E:\FR\FM\20APR1.SGM 20APR1 23156 Federal Register / Vol. 81, No. 76 / Wednesday, April 20, 2016 / Rules and Regulations the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

Airworthiness Directives; Turbomeca S.A. Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Turbomeca S.A. Arriel 2E turboshaft engines. This AD requires removing 
the pre-TU 193 adjusted high-pressure/low-pressure pump and metering 
valve assembly and replacing it with a part that is eligible for 
installation. This AD also requires replacing the constant delta-
pressure (delta-P) diaphragm of the fuel metering valve. This AD was 
prompted by reports of fuel flow non-conformities found during 
acceptance tests of Arriel 2E hydro-mechanical metering units (HMUs). 
We are issuing this AD to prevent failure of the delta-P diaphragm, 
which could result in an uncommanded in-flight shutdown and damage to 
the helicopter.

DATES: This AD becomes effective May 25, 2016.

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 January 4, 2016 (81 FR 
30). The NPRM proposed to correct an unsafe condition for the specified 
products. The MCAI states:

    Fuel flow non-conformities were found during reception tests of 
ARRIEL 2E Hydraulic Mechanical Metering Unit (HMU). Investigation 
and instrumented tests revealed instabilities on the additional 
check valve. These instabilities lead to hydraulic pulses. All HMU 
installed on ARRIEL 2E and 2N engines could present these 
instabilities.
    This condition, if not corrected, could lead to life reduction 
of the delta pressure valve diaphragm, and consequently, an 
uncommanded engine power increase, or an uncommanded in flight 
shutdown, possibly resulting in an emergency landing.

    You may obtain further information by examining the MCAI in the AD 
docket on the Internet at https://www.regulations.gov by searching for 
and locating Docket No. FAA-2015-5539.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (81 FR 30, January 4, 
2016).

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 (MSB) No. 292 
73 2193, Version A, dated July 16, 2015. The MSB describes procedures 
for incorporating modification TU 193 and replacing the constant delta-
P diaphragm of the fuel metering valve.

Costs of Compliance

    We estimate that this AD affects 12 engines installed on 
helicopters 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. Required parts cost about $13,400 per engine. Based on 
these figures, we estimate the cost of this AD on U.S. operators to be 
$162,840.

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

[[Page 23156]]

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.
