Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2016-0258, dated December 16, 
2016, to correct an unsafe condition for Airbus Helicopters Model AS 
365 N2 and AS 365 N3 helicopters with certain serial numbers and 
configurations. EASA advises of in-production helicopters with lower 
strobe light wiring harnesses that were interfering with either the 
helicopter structure or the adjacent fuel tank support. EASA further 
states that an investigation determined that the electrical harnesses 
of these lower strobe lights were manufactured with additional length 
to facilitate removal and installation of the lower strobe light 
assembly. However, the additional length of wiring in the harness was 
not properly secured to the helicopter structure. According to EASA, 
this could result in chafing of the harness on the helicopter 
structure, creating an ignition source adjacent to the inboard fuel 
tank vapor space, and result in a fuel tank fire.
    To address this unsafe condition, the EASA AD requires installing a 
cable mount, inspecting the lower strobe light electrical harness for 
damage, and re-routing the electrical harness.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, its technical 
representative, has notified us of the unsafe condition described in 
its AD. We are proposing this AD because we evaluated all known 
relevant information and determined that an unsafe condition is likely 
to exist or develop on other products of the same type design.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Helicopters Alert Service Bulletin (ASB) No. 
AS365-05.00.73, Revision 1, dated December 12, 2016 (ASB AS365-
05.00.73), which specifies procedures for inspecting the lower strobe 
light electrical harness for interference and chafing with the 
helicopter structure and also specifies procedures for installing a 
cable mount to secure the electrical harness. These procedures 
correspond to Airbus Helicopters modification (MOD) 365P084778.00.
    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.

Proposed AD Requirements

    This proposed AD would require, within 50 hours time-in-service 
(TIS), installing a cable mount on the helicopter structure and 
inspecting the lower strobe light electrical harness and the electrical 
harness between the cut-off connector and Frame 2000 for torn spiral 
tape and for any chafing on the harness cables. If the spiral tape is 
torn, the proposed AD would require, before further flight, replacing 
the spiral tape.

[[Page 21965]]

If there is any chafing on the cable the proposed AD would require, 
before further flight, replacing the harness.
    Helicopters in a MOD 365P084778.00 configuration have already 
accomplished the actions required by this proposed AD.

Differences Between This Proposed AD and the EASA AD

    The EASA AD limits the applicability to helicopters with a lower 
strobe light installed and with certain serial numbers or that are in a 
configuration based upon a modification, service information, or 
engineering drawings. This proposed AD would apply to all Model AS 365 
N2 and AS 365 N3 helicopters with a lower strobe light installed.

Costs of Compliance

    We estimate that this proposed AD would affect 30 helicopters of 
U.S. Registry.
    We estimate that operators may incur the following costs in order 
to comply with this AD. At an average labor rate of $85 per work-hour, 
installing a cable mount and inspecting the strobe light wiring 
harnesses would require about 1 hour, and required parts would cost 
about $50, for a cost per helicopter of $135 and a total cost of $4,050 
to all U.S. operators.
    If required, replacing torn spiral tape would require about 1 work-
hour, and required parts would cost $45, for a cost per helicopter of 
$130.
    If required, replacing a chafed wiring harness between the cut-off 
connector and Frame 2000 would require about 3 work-hours, and required 
parts would cost $90, for a cost per helicopter of $345.
    If required, replacing a chafed lower strobe light wiring harness 
would require about 3 work-hours, and required parts would cost $154, 
for a cost per helicopter of $409

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 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, I certify this 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.
