Airworthiness Directives; EADS CASA (Type Certificate Previously 
Held by Construcciones Aeronauticas, S.A.) Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
EADS CASA (Type Certificate previously held by Construcciones 
Aeronauticas, S.A.) Model CN-235, CN-235-100, CN-235-200, CN-235-300, 
and C-295 airplanes. This AD requires inspection of the feeder cables 
of certain fuel booster pumps for damage (including, but not limited 
to, signs of electrical arcing and fuel leaks), and replacement if 
necessary. This AD was prompted by a report of an in-flight problem 
with the fuel transfer system. We are issuing this AD to detect and 
correct damage to certain fuel booster pumps, which could create an 
ignition source in the fuel tank vapor space, and result in a fuel tank 
explosion and consequent loss of the airplane.

DATES: This AD becomes effective December 2, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 2,

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 http://www.regulations.gov 
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.
     For Model CN-235 airplanes: Airbus Military All Operator 
Letter 235-025, dated July 29, 2013.
     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 http://www.regulations.gov, 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:

                                   boost pump.
----------------------------------------------------------------------------------------------------------------

    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.
