Airworthiness Directives; Airbus Helicopters (Previously 
Eurocopter France) (Airbus Helicopters) Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for Airbus 
Helicopters Model SA-365N, SA-365N1, AS-365N2, and AS 365 N3 
helicopters to require repetitively inspecting frame number (No.) 9 for 
a crack. This AD was prompted by a report of a crack in frame No. 9 on 
an AS365 helicopter. The actions of this AD are intended to detect a 
crack and prevent loss of structural integrity and subsequent loss of 
control of the helicopter.

DATES: This AD is effective July 15, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain document listed in this AD as of July 15, 2014.

ADDRESSES: For service information identified in this AD, contact

SUPPLEMENTARY INFORMATION:

Discussion

    On November 6, 2013, at 78 FR 66668, the Federal Register published 
our notice of proposed rulemaking (NPRM), which proposed to amend 14 
CFR part 39 by adding an AD that would apply to Eurocopter (now Airbus 
Helicopters) Model SA-365N, SA-365N1, AS-365N2, and AS 365 N3 
helicopters. The NPRM proposed to 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, the NPRM proposed to 
require the inspection within 110 hours TIS and every 110 hours TIS 
thereafter. If there is a crack, the NPRM proposed to require, before 
further flight, repairing the crack. The proposed requirements were 
intended to detect a crack and prevent loss of structural integrity and 
subsequent loss of control of the helicopter.
    The NPRM was prompted by AD No. 2012-0108-E, dated June 15, 2012 
(AD 2012-0108-E), issued by EASA, which is the Technical Agent for the 
Member States of the European Union, 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 discovered 
during the ``T'' inspection of a Model AS365 helicopter started at a 
rivet hole of a doubler installed on the frame No. 9 in accordance with 
Eurocopter Alert Service Bulletin (ASB) No. 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.
    Since we issued the NPRM, Eurocopter France has changed its name to 
Airbus Helicopters. This AD reflects that change and updates the 
contact information to obtain service documentation.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we did not receive any comments on the NPRM (78 FR 66668, 
November 6, 2013).

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 
the EASA AD. We are issuing this AD because we evaluated all 
information provided by EASA and determined the unsafe condition exists 
and is likely to exist or develop on other helicopters of these same 
type designs and that air safety and the public interest require 
adopting the AD requirements as proposed except for the minor change 
previously described. This change is consistent with the intent of the 
proposals in the NPRM (78 FR 66668, November 6, 2013) and will not 
increase the economic burden on any operator nor increase the scope of 
the AD.

Differences Between This AD and the EASA AD

    The EASA AD requires contacting Eurocopter (now Airbus Helicopters) 
for repair instructions if there is a crack, and this AD does not. This 
AD applies to all Model 365 helicopters, not just those that were 
altered or repaired in accordance with specific Eurocopter 
modifications (MODs).

Related Service Information

    Eurocopter 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 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

[[Page 33051]]

Eurocopter for further procedures if there is a crack.

Costs of Compliance

    We estimate that this AD affects 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 labor rate of $85 per work-hour, 
inspecting LH and RH frame No. 9 will 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 will 
require about 20 work-hours, and required parts will 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 regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on helicopters 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
