DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2014-0379; Directorate Identifier 2013-SW-067-AD; 
Amendment 39-17870; AD 2014-12-09]
RIN 2120-AA64


Airworthiness Directives; Agusta S.p.A. (Agusta) 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 Agusta 
Model AB412 helicopters. This AD requires inspecting the main 
transmission lubricating system oil outlet hose (hose) for damage, and, 
if required, replacing the hose. This AD is prompted by reports of 
damage found on the hose. These actions are intended to prevent loss of 
main gear box (MGB) lubrication, which could lead to failure of the MGB 
and subsequent loss of control of the helicopter.

DATES: This AD becomes effective July 7, 2014.
    We must receive comments on this AD by August 18, 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 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590-0001.
     Hand Delivery: Deliver to the ``Mail'' address between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the Docket Operations Office

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

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Emergency AD No. 2013-0282-E, dated November 27, 2013, to correct an 
unsafe condition for Agusta Model AB 212, AB 412, and AB 412EP 
helicopters. EASA advises of two reports of oil leakage from the main 
transmission lubricating system oil outlet hose, part number 70-
061L275W210A, caused by damage on the hose. EASA further states an 
investigation has not determined the root cause, but that relative 
movement between the data plate and the hose assembly may have been a 
contributing factor. EASA advises that if not corrected, this condition 
could lead to transmission lubricating system failure and reduced 
control of the helicopter.
    As a result, EASA Emergency AD No. 2013-0282-E requires inspecting 
the portion of the hose accessible through the cargo hook opening for 
damage within 10 flight hours, and every 100 flight hours thereafter, 
and inspecting the portion of the hose accessible through the left side 
of the pylon for damage within 35 flight hours, and every 25 flight 
hours thereafter. If there is damage to the hose, EASA Emergency AD No. 
2013-0282-E requires replacing the hose with a serviceable hose.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Italy and are approved for operation in the United States. Pursuant to 
our bilateral agreement with Italy, 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 Agusta Bollettino Tecnico (BT) No. 412-137, dated 
November 26, 2013. BT No. 412-137 describes procedures for repetitively 
inspecting the stainless steel hose braiding beneath the hose data 
plates for damage, fretting, or broken wires.

AD Requirements

    This AD requires:
     Within 10 hours time-in-service (TIS), and thereafter at 
intervals not to exceed 100 hours TIS, inspecting the stainless steel 
hose braiding for damage, fretting, and broken wires in the area below 
the transmission oil sump, in the external cargo hook opening.
     Within 35 hours TIS, and thereafter at intervals not to 
exceed 25 hours TIS, inspecting the stainless steel hose braiding for 
damage, fretting, and broken wires in the area of the transmission oil 
sump behind the left side pylon access door.
     If there is any damage, fretting, or any broken wires, 
replacing the hose before further flight.

Differences Between This AD and the EASA AD

    This AD does not apply to Model AB 212 or AB 412EP helicopters, as 
these models are not type-certificated in the U.S.

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 and that good cause exists 
for making this amendment effective in less than 30 days.

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.
