Airworthiness Directives; AQUILA--Aviation by Excellence AG 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments

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

SUMMARY: We are adopting a new airworthiness directive (AD) AQUILA--
Aviation by Excellence AG Model AT01 airplanes. This AD results from 
mandatory continuing airworthiness information (MCAI) issued by the 
aviation authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as a defective sealing of a tapped through bore hole at the 
inside of the fuel tank openings in combination with prolonged periods 
at maximum fuel level. We are issuing this AD to require actions to 
address the unsafe condition on these products.

DATES: This AD is effective December 30, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of December 30, 
2013.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2013-0236, dated September 25, 2013

[[Page 70201]]

(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    During repair in the wing tank area it was discovered that, when 
the tank is filled to a maximum level, fuel can soak into the upper 
shell sandwich of the wings. This can be detected from damaged 
finishing of the upper wing shells or from yellow discoloured 
bonding wire insulation.
    The root cause is a defective sealing of a tapped through bore 
hole at the inside of the fuel tank openings in combination with 
prolonged periods at maximum fuel level.
    This condition, if not detected and corrected, could cause long-
term structural degradation of the wing structure.
    To address this potential unsafe condition, AQUILA issued 
Service Bulletin (SB)-AT01-027 providing instructions for the 
inspection and sealing of tapped bore holes inside both fuel tank 
openings.
    For the reasons described above, this AD requires repetitive 
inspections of the wing tank area and, depending on findings, 
corrective actions.

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-
2013-0963.

Relevant Service Information

    AQUILA Aviation GmbH issued Vorgeschrieben Technische Mitteilung 
SB-AT01-027, dated August 15, 2013 (English translation: Mandatory 
Service Bulletin SB-AT01-027, Issue A.02, dated August 15, 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 the 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 this State of Design Authority, they 
have 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 the State of Design Authority 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 there 
are no airplanes currently on the U.S. registry and thus, does not have 
any impact upon the public. Therefore, we find that notice and 
opportunity for prior public comment are unnecessary.

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-2013-0963; Directorate 
Identifier 2013-CE-034-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 will affect 0 products of U.S. registry. 
We also estimate that it will take about 2 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour.
    Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $0, or $0 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 2 work-hours and require parts costing $100, for a cost of 
$270 per product. We have no way of determining the number of products 
that may need these actions.

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 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.

openings in combination with prolonged periods at maximum fuel 
level. We are issuing this AD to detect and correct a defective 
sealing of a tapped through bore hole at the inside of the fuel tank 
openings, which if not detected and corrected, could cause long-term 
structural degradation of the wing structure.

(f) Actions and Compliance
