Unsafe Condition
Flaking of the cadmium coating of electrical magnetic plugs head Part Number (P/N) 9 520 01 154 5 was detected. Investigation results indicate that this was the result of manufacturing deficiency. This part is installed on electrical magnetic plugs (front and rear position) of the engine, providing warning signals for early detection of internal part(s) structural degradation, propagating in form of presence of metal particles in the lubrication system. The subsequent investigation identified the batch of affected magnetic plugs heads by serial number (s/n). This condition, if not detected and corrected, could lead to reduced capability of the particle detection system to identify internal structural failures and consequent in-flight shut-down, resulting in forced landing with possible damage to the helicopter and injury to occupants.

SUPPLEMENTARY INFORMATION:
Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD 2018-0012-E, dated January 16, 2018 (referred to hereinafter as
``the MCAI''), to address an unsafe condition for the specified
products. The MCAI states:
Flaking of the cadmium coating of electrical magnetic plugs head
Part Number (P/N) 9 520 01 154 5 was detected. Investigation results
indicate that this was the result of manufacturing deficiency. This
part is installed on electrical magnetic plugs (front and rear
position) of the engine, providing warning signals for early
detection of internal part(s) structural degradation, propagating in
form of presence of metal particles in the lubrication system. The
subsequent investigation identified the batch of affected magnetic
plugs heads by serial number (s/n).
This condition, if not detected and corrected, could lead to
reduced capability of the particle detection system to identify
internal structural failures and consequent in-flight shut-down,
resulting in forced landing with possible damage to the helicopter
and injury to occupants.
To address this potential unsafe condition, Safran Helicopter
Engines issued Alert Mandatory Service Bulletin (MSB) A319 79 4840
and Alert MSB A319 79 4841 to provide inspection and replacement
instructions.
You may obtain further information by examining the MCAI in the AD
docket on the internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for
and locating Docket No. FAA-2018-0084.
Related Service Information Under 1 CFR Part 51
We reviewed Safran Helicopter Engines Alert Mandatory Service
Bulletin (MSB) No. A319 79 4840, Version A, dated November 27, 2017,
and Safran Helicopter Engines Alert MSB No. A319 79 4841, Version A,
dated November 20, 2017. The MSBs describe procedures, respectively,
for inspecting and replacing the magnetic heads installed on the
electrical magnetic plugs. 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.
FAA's Determination
This product has been approved by France and is approved for
operation in the United States. Pursuant to our bilateral agreement
with the European Community, EASA has notified us of the unsafe
condition described in the MCAI and service information referenced
above. 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 products of the same type design.
AD Requirements
This final rule requires inspection and replacement of the magnetic
heads installed on oil system electrical magnetic plugs.
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 compliance time for the action is less than the time
required for public comment. Therefore, we find good cause that notice
and opportunity for prior public comment are impracticable. In
addition, for the reason stated above, we find that good cause exists
for making this amendment effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, we invite you to send any written data, views, or
arguments about
[[Page 9425]]
this final rule. Send your comments to an address listed under the
ADDRESSES section. Include the docket number FAA-2018-0084 and Product
Identifier 2018-NE-02-AD at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this final rule. We will consider
all comments received by the closing date and may amend this final rule
because of those comments.
We will post all comments we receive, without change, to <a href="http://www.regulations.gov">http://www.regulations.gov</a>, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this final rule.
Costs of Compliance
We estimate that this AD affects 105 engines installed on
helicopters of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
ARRIUS 2F Rear Electrical Mag Plug 2 work-hours x $85 per $0 $170 $17,850

ARRIUS 2F Front and Rear Electrical 4 work-hours x $85 per 3,061 3,401 357,105
Mag Plug Mag Head Replacement. hour = $340.
----------------------------------------------------------------------------------------------------------------
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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to engines, propellers, and
associated appliances to the Manager, Engine and Propeller Standards
Branch, Policy and Innovation Division.
Regulatory Findings
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 above, I certify this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, 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.
