We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On May 23, 2013, we issued AD 2013–11–09, Amendment 39–17469 (78 FR 32551, May 31, 2013), ‘‘AD 2013– 11–09’’ for all Turbomeca S.A. Arrius 2B, 2B1, and 2F turboshaft engines. Depending on the engine model, AD 2013–11–09 requires the repetitive replacement of the fuel injector manifolds and privilege injector, or only the privilege injector. AD 2013–11–09 resulted from a report that the corrective actions of AD 2001–08–14, R1, Amendment 39–14423 (71 FR 2993, January 19, 2006) were insufficient to eliminate the unsafe condition. We issued AD 2013–11–09 to prevent an engine flameout of Arrius 2B1 and 2F turboshaft engines and damage to the helicopter. Actions Since AD 2013–11–09 Was Issued Since we issued AD 2013–11–09, we received reports of engine flameouts as a result of reduced fuel flow due to the presence of coking. Also since we issued AD 2013–11–09, the European Aviation Safety Agency (EASA) has issued AD 2017–0070, dated April 25, 2017, which requires replacement of pipe injector preferred assemblies, P/N 0 319 73 835 0, with improved assembly, P/N 0 319 73 044 0, on Arrius 2F engines. Related Service Information We reviewed Safran Helicopter Engines, S.A., Service Bulletin (SB) No. 319 73 4839, Version A, dated December 13, 2016. The SB describes procedures for replacing pipe injector preferred assemblies. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require, for Arrius 2B1 turboshaft engines, initial and repetitive replacement of the main fuel injector half-manifolds and preferred injector with a part eligible for installation within the compliance times specified. This proposed AD would also require, for Arrius 2F turboshaft engines, initial and repetitive replacement of the preferred injector and replacing pipe injector preferred assemblies, P/N 0 319 73 835 0, with assembly, P/N 0 319 73 044 0. Costs of Compliance We estimate that this proposed AD affects 50 Arrius 2B1 and 105 Arrius 2F turboshaft engines installed on helicopters of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Cost per product Labor cost Arrius 2B1 fuel injector manifolds and injector replacement. Arrius 2F pipe injector preferred assembly replacement. 3 work-hours × $85 per hour = $255 ............. $0 $255 $12,750 3 work-hours × $85 per hour = $255 ............. 3,154 3,409 357,945 pmangrum on DSK3GDR082PROD with PROPOSALS 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. This AD is issued in accordance with authority delegated by the Executive VerDate Sep<11>2014 14:55 Aug 24, 2017 Jkt 241001 Parts cost Cost on U.S. operators Action Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to engines, propellers, and associated appliances to the Manager, Engine and Propeller Standards Branch, Policy and Innovation Division. Regulatory Findings We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation: PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 (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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: E:\FR\FM\25AUP1.SGM 25AUP1 Federal Register / Vol. 82, No. 164 / Friday, August 25, 2017 / Proposed Rules PART 39—AIRWORTHINESS DIRECTIVES 1.

Airworthiness Directives; Safran Helicopter Engines, S.A., 
Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede airworthiness directive (AD) 2013-11-
09 that applies to all Safran Helicopter Engines, S.A., Arrius 2B1 and 
2F turboshaft engines. Depending on the engine model, AD 2013-11-09 
requires the repetitive replacement of the fuel injector manifolds and 
privilege injector, or only the privilege injector. Since we issued AD 
2013-11-09, we received reports of engine flameouts as a result of 
reduced fuel flow due to the presence of coking. This proposed AD would 
retain the repetitive hardware replacement requirements of AD 2013-11-
09, but only allow replacement pipe injector preferred assembly, part 
number (P/N) 0 319 73 044 0, on the Arrius 2F engines. We are proposing 
this AD to correct the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by October 10, 
2017.

Discussion

    On May 23, 2013, we issued AD 2013-11-09, Amendment 39-17469 (78 FR 
32551, May 31, 2013), ``AD 2013-11-09'' for all Turbomeca S.A. Arrius 
2B, 2B1, and 2F turboshaft engines. Depending on the engine model, AD 
2013-11-09 requires the repetitive replacement of the fuel injector 
manifolds and privilege injector, or only the privilege injector. AD 
2013-11-09 resulted from a report that the corrective actions of AD 
2001-08-14, R1, Amendment 39-14423 (71 FR 2993, January 19, 2006) were 
insufficient to eliminate the unsafe condition. We issued AD 2013-11-09 
to prevent an engine flameout of Arrius 2B1 and 2F turboshaft engines 
and damage to the helicopter.

Actions Since AD 2013-11-09 Was Issued

    Since we issued AD 2013-11-09, we received reports of engine 
flameouts as a result of reduced fuel flow due to the presence of 
coking. Also since we issued AD 2013-11-09, the European Aviation 
Safety Agency (EASA) has issued AD 2017-0070, dated April 25, 2017, 
which requires replacement of pipe injector preferred assemblies, P/N 0 
319 73 835 0, with improved assembly, P/N 0 319 73 044 0, on Arrius 2F 
engines.

Related Service Information

    We reviewed Safran Helicopter Engines, S.A., Service Bulletin (SB) 
No. 319 73 4839, Version A, dated December 13, 2016. The SB describes 
procedures for replacing pipe injector preferred assemblies.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require, for Arrius 2B1 turboshaft engines, 
initial and repetitive replacement of the main fuel injector half-
manifolds and preferred injector with a part eligible for installation 
within the compliance times specified. This proposed AD would also 
require, for Arrius 2F turboshaft engines, initial and repetitive 
replacement of the preferred injector and replacing pipe injector 
preferred assemblies, P/N 0 319 73 835 0, with assembly, P/N 0 319 73 
044 0.

Costs of Compliance

    We estimate that this proposed AD affects 50 Arrius 2B1 and 105 
Arrius 2F turboshaft engines installed on helicopters of U.S. registry.
    We estimate the following costs to comply with this proposed AD:

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

Regulatory Findings

    We have determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    (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.
