Discussion

    EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD No. 2014-0279, dated December 19,
2014, to correct an unsafe condition for Romtex Model 358 torso
restraint systems installed on Airbus Helicopters Model EC130T2,
AS350B2, and AS350B3 helicopters. EASA advises that ruptures have
occurred on the upper side (knob) of several rotary buckles installed
on these restraint systems. EASA further states an investigation
revealed the material used in two batches of the rotary buckle sub-
assembly (buckle assembly) were altered by a supplier, resulting in a
specification different from the approved design data. The EASA AD
states that this condition could prevent the release of the restraint
system straps as intended after an emergency landing. To address this
unsafe condition, the EASA AD requires inspecting the buckle assembly
for proper operation, replacing or marking as inoperative any buckle
assembly that fails to release the straps before further flight, and
replacing all buckle assemblies within 6 months. The EASA AD also
prohibits installing these buckle assemblies on any aircraft.

FAA's Determination

    These products have been approved by the aviation authority of
Romania and are approved for operation in the United States. Pursuant
to our bilateral agreement with Romania, 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 Romtex Service Bulletin No. 358SB-14-101, Revision 1,
dated December 12, 2014 (SB 358SB-14-101), which specifies removing
from service certain part-numbered and serial-numbered buckle
assemblies, consisting of the rotary buckle, belt, and attachment.
    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

    For buckle assemblies with a part number and serial number
identified in Romtex SB 358SB-14-101, this proposed AD would require,
within 30 hours, inspecting the buckle assembly to determine whether
the straps release. If the buckle fails to release the straps, this
proposed AD would require marking the seat as inoperative and replacing
the buckle assembly within 180 hours TIS. If the buckle releases the
straps, this proposed AD would require replacing the buckle assembly
within 180 hours. The proposed AD would also prohibit installing the
affected buckle assemblies on any helicopter.

Differences Between This Proposed AD and the EASA AD

    The EASA AD requires compliance within 30 days for the buckle
inspection and 6 months for replacement; this proposed AD would require
the inspection within 30 hours TIS and replacement within 180 hours
TIS. The EASA AD does not apply to Model EC130B4 and AS355NP
helicopters, and this proposed AD would.

Costs of Compliance

    We estimate that this proposed AD would affect 893 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 hour,
inspecting the buckle assembly would require about .5 work-hour, for a
cost per helicopter of $43 and a total cost of $38,399 for the fleet.
Replacing each buckle assembly would require about .5 work-hour, and
required parts would cost $42,000, for a cost per helicopter of $42,043
and a total cost to U.S. operators of $37,544,399.
    According to the Romtex service information, some of the costs of
this proposed AD may be covered under warranty, thereby reducing the
cost impact on affected individuals. We do not control warranty
coverage by Romtex. Accordingly, we have included all costs in our cost
estimate.

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.
