    tions, and subsequent loss of control of the helicopter.

(c) EFFECTIVE DATE

    This AD becomes effective April 13, 2018.

(d) COMPLIANCE

    You are responsible  for  performing  each  action required by this AD
    within the specified compliance time unless it has already been accom-
    plished prior to that time.

(e) REQUIRED ACTIONS

(1) For helicopters listed in paragraph (a)(1) of this AD:

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 AD No. 2017-0176-E, dated September 14,
2017, to correct an unsafe condition for Leonardo S.p.A. (previously
Agusta) Model A109E, A109LUH, A109S, AW109SP, A119, and AW119 MKII
helicopters. EASA advises of an in-flight loss of an MRB tip cap on an
AW109SP helicopter where the pilot was able to safely land the
helicopter. EASA further advises that an investigation determined the
cause as incorrect bonding procedures used between specific dates and
identified the affected MRBs by part number and serial number.
According to EASA, this condition could result in loss of an MRB tip
cap, increased pilot workload, and reduced control of the helicopter.
To address this unsafe condition, the EASA AD requires repetitive
inspections of the MRB tip caps and replacing certain part-numbered
MRBs.
The FAA is in the process of updating Agusta's name change to
Leonardo Helicopters on its type certificate. Because this name change
is not yet effective, this AD specifies Agusta.

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 Under 1 CFR Part 51

Leonardo Helicopters has issued Emergency Alert Service Bulletin
(EASB) No. 109EP-157 for Model A109E helicopters, EASB No. 109S-077 for
Model A109S helicopters, and EASB No. 109SP-116 for Model AW109SP
helicopters, all dated September 8, 2017. Leonardo Helicopters has also
issued EASB No. 119-085, Revision A, dated September 11, 2017, for
Model A119 and AW119 MKII helicopters. This service information
identifies certain part-numbered and serial-numbered MRBs for
applicability and describes procedures for tap inspecting the tip cap
for disbonding.
This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section.

AD Requirements

For helicopters with an MRB part number 709-0104-01-111 with serial
number 1307, 1320, 1346, 1365, 1372, 1380, 1414, 1426, 1436, 1475, or
1485 installed, this AD requires, within 5 hours time-in-service (TIS)
and thereafter at intervals not exceeding 5 hours TIS, tap inspecting
the MRB tip cap for disbonding and, if there is disbonding, removing
the MRB from service before further flight. If there is no disbonding
on any of the inspections, this AD requires removing the MRB from
service within 25 hours TIS. After the effective date of this AD, this
AD prohibits installing these serial-numbered MRBs on any helicopter.
For all other helicopters, this AD requires, within 25 hours TIS
and thereafter at intervals not exceeding 25 hours TIS, tap inspecting
the MRB tip cap for disbonding. If there is any disbonding, this AD
requires removing the MRB from service before further flight. The
repetitive inspections required for these MRBs would no longer be
required after the MRB accumulates 400 hours TIS.

Differences Between This AD and the EASA AD

The EASA AD applies to Model A109LUH helicopters, while this AD
does not as that model helicopter is not type-certificated in the U.S.
The EASA AD requires that you contact Leonardo Helicopters, and this AD
does not.

Costs of Compliance


We estimate that this AD affects 130 helicopters of U.S. Registry.
At an average labor rate of $85 per work-hour, we estimate that
operators may incur the following costs in order to comply with this
AD. Tap inspecting the MRB tip caps will require 1 work-hour, for a
cost per helicopter of $85 and a cost of $11,050 for the U.S. fleet per
inspection cycle. If required, replacing one MRB will require 4 work-
hours and required parts will cost $89,179, for a cost per helicopter
of $89,519.
According to Leonardo Helicopters' service information, some of the
costs of this AD may be covered under warranty, thereby reducing the
cost impact on affected individuals. We do not control warranty
coverage by Leonardo Helicopters. Accordingly, we have included all
costs in our cost estimate.

FAA's Justification and Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies waiving notice and comment prior to adoption of this rule
because the corrective actions required by this AD must be accomplished
within 5 hours TIS and 25 hours TIS.
Therefore, we find good cause that notice and opportunity for prior
public comment are impracticable. In addition, for the reasons stated
above, we find 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.
We prepared an economic evaluation of the estimated costs to comply
with this AD and placed it in the AD docket.
