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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Safran Helicopter Engines, S.A., Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 
1D1, 1E2, 1K1, 1S, and 1S1 turboshaft engines. Emergency AD 2017-04-51 
was sent previously to all known U.S. owners and operators of these 
engines. This AD requires inspecting, wrapping, and replacing the 
affected drain valve assembly (DV) installed on these Arriel 1 engines. 
This AD was prompted by reports of fuel leaks originating from the DV 
on certain Arriel engines. We are issuing this AD to correct the unsafe 
condition on these products.

persons to whom it was made immediately effective by Emergency AD 2017-
04-51, issued on February 8, 2017, which contained the requirements of 
this amendment.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication identified in this AD as of March 
30, 2017.

SUPPLEMENTARY INFORMATION: 

Discussion

    On February 8, 2017, we issued Emergency AD 2017-04-51, which 
requires inspecting, wrapping, and replacing the DV. This emergency AD 
was sent previously to all known U.S. owners and operators of these 
Safran Helicopter Engines, S.A., Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 
1D1, 1E2, 1K1, 1S, and 1S1 turboshaft engines. This action was prompted 
by reports of fuel leaks originating from the DV on certain Arriel 
engines. This condition, if not corrected, could result in engine 
compartment fire, in-flight shutdown, and damage to the helicopter.

Relevant Service Information Under 1 CFR Part 51

    We reviewed Safran Helicopter Engines Alert Mandatory Service 
Bulletin A292 73 0851, Version A, dated January 31, 2017. The MSB 
describes procedures for inspecting, wrapping, and replacing the DV. 
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.

FAA's Determination

    We are issuing 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.

AD Requirements

    This AD requires inspecting, wrapping, and replacing the DV.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because the 
compliance requirements are within 10 flight hours or 7 days. 
Therefore, we find that notice and opportunity for prior public comment 
are impracticable and that good cause exists for making this amendment 
effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2017-0115 and 
Directorate Identifier 2017-NE-04-AD at the beginning of your comments. 
We specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 70 engines installed on 
helicopters of U.S. registry.
    We estimate the following costs to comply with this 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.

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.

    (ii) Visually inspect the affected DV for fuel leakage.
    (A) If a fuel leak is detected, replace the affected DV with a 
DV eligible for installation, before the next flight.
    (B) If no fuel leak is detected, before next flight, wrap the 
affected DV with a self-amalgamate tape using the Accomplishment 
Instructions, paragraph 2, of Safran Helicopter Engines Alert MSB
