14 CFR Part 39

[Docket No. FAA-2014-0832; Directorate Identifier 2014-SW-044-AD; 
Amendment 39-17995; AD 2014-21-03]
RIN 2120-AA64


Airworthiness Directives; Airbus Helicopters (Previously 
Eurocopter France) Helicopters

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for Airbus 
Helicopters Model AS332L2 helicopters with a certain yaw control damper 
support (support) installed. This AD requires repetitively inspecting 
the support attachment points for a crack. This AD is prompted by a 
report that the front attachment points of several supports were found 
to have cracks. These actions are intended to detect a crack in a 
support, which could result in failure of the support, separation of 
the yaw damper unit, blocking of the yaw flight control channel, and 
reduced control of the helicopter.

DATES: This AD becomes effective November 12, 2014.
    We must receive comments on this AD by December 26, 2014.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your 
comments electronically.
     Fax: 202-493-2251.
     Mail: Send comments to the U.S. Department of

SUPPLEMENTARY INFORMATION: 

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments prior to it becoming effective. However, we 
invite you to participate in this rulemaking by submitting written 
comments, data, or views. We also invite comments relating to the 
economic, environmental, energy, or federalism impacts that resulted 
from adopting this AD. The most helpful comments reference a specific 
portion of the AD, explain the reason for any recommended change, and 
include supporting data. To ensure the docket does not contain 
duplicate comments, commenters should send only one copy of written 
comments, or if comments are filed electronically, commenters should 
submit them only one time. We will file in the docket all comments that 
we receive, as well as a report summarizing each substantive public 
contact with FAA personnel concerning this rulemaking during the 
comment period. We will consider all the comments we receive and may 
conduct additional rulemaking based on those comments.

Discussion

    This AD is prompted by AD No. 2014-0080, dated March 27, 2014, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union, to correct an unsafe condition for Airbus 
Helicopters Model AS332L2 helicopters with a support part number (P/N) 
332A25-1334-00 installed. EASA advises of several reports of cracks on 
the two front attachment points of the support, and that subsequent 
investigations determined pilot actions on the yaw pedals could 
generate detrimental loading conditions on the support attachment 
points and initiate a crack. EASA also states that a crack could lead 
to structural failure of the support, detachment of the damper unit, 
possible blocking of the yaw flight control channel, and reduced 
control of the helicopter. EASA AD No. 2014-0080 requires repetitive 
inspections of the support and, if there is a crack, replacing the 
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 
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 the same type 
design.

Related Service Information

    We reviewed Airbus Helicopters Alert Service Bulletin No. AS332-
05.00.98, Revision 0, dated March 26, 2014 (ASB), for Model AS332L2 
helicopters. This ASB describes procedures for inspecting the support 
attachment points for a crack and, if there is a crack, requires 
replacing the support.

AD Requirements

    This AD requires, for helicopters with 3,900 or more hours time-in-
service (TIS), within 100 hours TIS and at intervals not exceeding 825 
hours TIS, repetitively inspecting each support, P/N 332-A25-1334-00, 
at its attachment points for a crack. If there is a crack, this AD 
requires replacing the support before further flight.

Interim Action

    We consider this AD to be an interim action. If final action is 
later identified, we might consider further rulemaking then.

Costs of Compliance

    There are no costs of compliance with this AD because there are no 
helicopters with this type certificate on the U.S. Registry.

FAA's Justification and Determination of the Effective Date

    There are no helicopters with this type certificate on the U.S. 
Registry. Therefore, we believe it is unlikely that we will receive any 
adverse comments or useful information about this AD from U.S. 
Operators.
    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we determined that notice and opportunity for 
public comment before issuing this AD are unnecessary because there are 
none of these products on the U.S. Registry.

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 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, 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.
