Federal Register Abstract
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.

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.
[[Page 35034]]
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:
<bullet> 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.
<bullet> 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.
<bullet> 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.
