Federal Register Abstract
We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB412 helicopters. This AD requires visually inspecting the main rotor swashplate outer ring (outer ring) for a crack and replacing that outer ring if a crack exists. This AD is prompted by two cases of cracks caused by fatigue on certain outer rings. These actions are intended to prevent the failure of the outer ring, which would lead to loss of main rotor blade pitch control and subsequently loss of helicopter control.

rings. These actions are intended to prevent the failure of the outer
ring, which would lead to loss of main rotor blade pitch control and
subsequently loss of helicopter control.

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
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD No. 2013-0152-E, dated July 17,
2013, to correct an unsafe condition for the Agusta Model AB412
helicopter. EASA advises
[[Page 10334]]
that two cases of cracks were reported in the outer ring, part number
(P/N) 412-010-407-105. A subsequent investigation revealed that
``fatigue failure'' caused the cracks. EASA states that ``this
condition, if not detected and corrected, could lead to the loss of
main rotor blade pitch control, possibly resulting in loss of control
of the helicopter.'' EASA calls for repetitive inspections of the
affected outer rings for a crack and replacing the outer ring with an
improved outer ring, P/N 412-010-107-117, if a crack is found. If the
outer ring has not been replaced, the AD requires replacing each outer
ring, P/N 412-010-407-105, with an improved outer ring, P/N 412-010-
107-117, within 300 flight hours or 8 months, whichever occurs first.
Replacement with an improved outer ring is terminating action for the
repetitive inspections, EASA states.
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 these same type designs.
Related Service Information
AgustaWestland S.p.A. issued Alert Bollettino Tecnico No. 412-134
on July 15, 2013 (BT), to warn that two cases of cracking in the outer
ring, P/N 412-010-407-105, have been reported, both attributed to
fatigue failure. The BT calls for visually inspecting the outer ring
for a crack with a 5X magnifying glass and a bright light. The BT added
that the inspection must occur within 5 flight hours from when the BT
was issued and within intervals of 25 flight hours thereafter until the
outer ring is replaced. The deadline to replace the outer ring with
outer ring, P/N 412-010-407-117, is 300 flight hours or no later than
April 15, 2014, whichever comes first. Outer ring, P/N 412-010-407-105,
was not to be used after April 15, 2014, the BT stated.
AD Requirements
This AD requires:
<bullet> Within 5 hours time-in-service (TIS), and thereafter at
intervals not to exceed 25 hours TIS, visually inspecting the
swashplate outer ring, P/N 412-010-407-105, for cracks, using a 5X
magnifying glass and a bright light. If a crack exists, before further
flight, removing the swashplate outer ring from service.
<bullet> Within 300 hours TIS or 8 months, whichever occurs first,
removing the swashplate outer ring, P/N 412-010-407-105, from service.
<bullet> Not installing a swashplate outer ring, P/N 412-010-407-
105, on any helicopter.
Differences Between This AD and the EASA AD
This AD prohibits installation of a swashplate outer ring, P/N 412-
010-407-105, while the EASA AD allows installation of this part under
certain conditions.
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.
