Airworthiness Directives; Eurocopter France (Eurocopter)
Helicopters
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for
[[Page 66669]]
Eurocopter Model SA-365N, SA-365N1, AS-365N2, and AS 365 N3

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA AD
No. 2012-0108-E, dated June 15, 2012 (AD 2012-0108-E), to correct an
unsafe condition for Eurocopter Model SA 365 N, SA 365 N1, AS 365 N2,
and AS 365 N3 helicopters with a frame No. 9 installed, if certain
``doublers or repairs have been installed.'' EASA advises that a crack
was discovered during the ``T'' inspection of an AS365 helicopter. The
crack started at a rivet hole of a doubler that was installed on the
frame No. 9 in accordance with Eurocopter Alert Service Bulletin (ASB)
53.00.42, dated January 31, 2001. EASA further states that structural
alteration of frame No. 9 by modifications or repairs can result in
fatigue crack initiation under normal operational loads. According to
EASA, this condition, if not corrected, could lead to crack propagation
and failure of frame No. 9, which would adversely affect the structural
integrity of the helicopter. For these reasons, AD 2012-0108-E requires
repetitive inspections of frame No. 9 for a crack in the area of the
doubler or any repair performed in the area of the latch support and
stretcher support.
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
Eurocopter has issued one Emergency ASB (EASB) with two numbers:
EASB No. 05.00.63, Revision 1, dated June 18, 2012, for Model AS365
helicopters and EASB No. 05.00.30, Revision 1, dated June 18, 2012, for
Model AS565 helicopters. The EASB applies to helicopters with a frame
No. 9 that has not been modified by modification (MOD) 07 53C17 or MOD
07 53D02, and that has had doublers installed or repairs performed in
accordance with certain service instructions. The EASB describes
procedures to inspect the frame No. 9 for a crack, and for contacting
Eurocopter for further procedures if there is a crack.
Proposed AD Requirements
This proposed AD would require, for helicopters that have a No. 9
frame that has had any repair or alteration made, within 10 hours time-
in-service (TIS) and every 110 hours TIS thereafter, inspecting the
left-hand (LH) and right-hand (RH) frame No. 9 for a crack in the areas
of the latch support and stretcher support with a 10X or higher power
magnifying glass. For all other helicopters, this proposed AD would
require this inspection within 110 hours TIS and every 110 hours TIS
thereafter. If there is a crack, the proposed AD would require, before
further flight, repairing the crack.
Differences Between This Proposed AD and the EASA AD
The EASA AD requires contacting Eurocopter for repair instructions
if there is a crack, and the proposed AD does not. The proposed AD
would apply to all Eurocopter 365 helicopters, not just those that were
altered or repaired in accordance with specific Eurocopter MODs.
Costs of Compliance
We estimate that this proposed AD would affect 37 helicopters of
U.S. Registry. We estimate that operators may incur the following costs
in order to comply with this AD. At an average
[[Page 66670]]
labor rate of $85 per hour, inspecting LH and RH frame No. 9 would
require about 3 work-hours, for a cost per helicopter of $255 and a
total cost to U.S. operators of $9,435 per inspection cycle. Repairing
a cracked frame No. 9 would require about 20 work-hours, and required
parts would cost about $10,000, for a cost per helicopter of $11,700.
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 proposed 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.
