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
Airworthiness Directive 2013-0186, dated August 16, 2013 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for the specified
products. The MCAI states:
An occurrence with a CN-235 aeroplane has been reported,
involving an in-flight problem with the fuel transfer system.
The results of the subsequent investigation revealed damage on
the fuel booster pump electrical feeding cable and some burn marks
on the pump body and plate (fairing) at the external side of the
fuel tank; confirmed electrical arcing between the wire and pump
body; and revealed as well fuel leakage onto the affected wire.
This condition, if not detected and corrected, could create an
ignition source in the fuel tank vapour space, possibly resulting in
a fuel tank explosion and loss of the aeroplane.
To address this potential unsafe condition, EADS CASA (Airbus
Military) issued All Operators Letter (AOL) 235-025 and AOL
[[Page 68689]]
295-025, providing inspection instructions for the affected fuel
booster pumps, Part Number (P/N) 1C12-34 and P/N 1C12-46.
For the reasons described above, this [EASA] AD requires a one-
time [detail visual] inspection of the affected fuel booster pumps
to detect damage [including, but not limited, to signs of electrical
arcing and fuel leaks] and, depending on findings, replacement of
the fuel booster pump. This [EASA] AD also requires the reporting of
all findings to EADS CASA for evaluation.
This [EASA] AD is considered to be an interim action and further
AD action may follow.
You may examine the MCAI on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a>
by searching for and locating it in Docket No. FAA-2013-0870.
Relevant Service Information
Airbus Military (EADS CASA) has issued the following service
information.
<bullet> For Model CN-235 airplanes: Airbus Military All Operator
Letter 235-025, dated July 29, 2013.
<bullet> For Model C-295 airplanes: Airbus Military All Operator
Letter 295-025, Revision 01, dated August 1, 2013.
The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.
FAA's Determination and Requirements of This AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are issuing this AD because we
evaluated all pertinent information and determined the unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because
damage to the fuel booster pump could create an ignition source in the
fuel tank vapor space, which could result in a fuel tank explosion and
consequent loss of the airplane. Therefore, we determined that notice
and opportunity for public comment before issuing this AD are
impracticable and that good cause exists for making this amendment
effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. We invite you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include ``Docket No. FAA-2013-0870; Directorate
Identifier 2013-NM-166-AD'' at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD 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 AD.
Costs of Compliance
We estimate that this AD affects 35 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators

We estimate the following costs to do any necessary replacements
that would be required based on the results of the inspection. We have
no way of determining the number of aircraft that might need this
replacement:

Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information
Collection Clearance Officer, AES-200.
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
[[Page 68690]]
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 above, I certify that 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.
