Airworthiness Directives; Stemme GmbH & Co. KG Model S10-VT 
Powered Sailplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. 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 leakage in the area of a plastic T-connector was found during 
a daily pre-flight check. The investigation has shown a crack in the 
centre part of this connector.

This AD requires actions that are intended to address the unsafe 
condition described in the MCAI.

DATES: This AD becomes effective February 20, 2008.
    On February 20, 2008, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in this 
AD.
    We must receive comments on this AD by March 3, 2008.

SUPPLEMENTARY INFORMATION:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued 
Emergency AD No. 2007-0315-E, dated December 21, 2007 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    A leakage in the area of a plastic T-connector was found during 
a daily pre-flight check. The investigation has shown a crack in the 
centre part of this connector.

    This proposed AD would require you to inspect all plastic 
connectors in the area of the fuel pumps and the connection point of 
the pressure lines to the fuel shut-off valve for possible leakage and 
replace the plastic connectors in the fuel system with metal connectors 
if leaks are found.
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    STEMME F & D has issued Service Bulletin A31-10-082, Am.-Index: 
01.a, dated November 30, 2007. 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.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might have also required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
described in a separate paragraph of the AD. These requirements take 
precedence over those copied from the MCAI.

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 a 
leak in the area of a fuel line plastic T-connector was found, which 
could result in the possibility of fuel leaking into the engine 
compartment. 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-2008-0105; Directorate 
Identifier 2008-CE-001-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 https://
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.

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 DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities

[[Page 5735]]

under the criteria of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

2. The FAA amends Sec.  39.13 by adding the following new AD:

2008-03-06 Stemme GmbH & Co. KG: Amendment 39-15355; Docket No. FAA-
2008-0105; Directorate Identifier 2008-CE-001-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective February 
20, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Model S10-VT powered sailplanes, serial 
numbers 11-001 through 11-112, except 11-036, 11-067, 11-068, and 
11-090, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 28: Fuel.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    A leakage in the area of a plastic T-connector was found during 
a daily pre-flight check. The investigation has shown a crack in the 
centre part of this connector.

This AD requires you to inspect all plastic connectors in the area 
of the fuel pumps and the connection point of the pressure lines to 
the fuel shut-off valve for possible leakage and replace the plastic 
connectors in the fuel system with metal connectors if leaks are 
found.

Actions and Compliance

    (f) Unless already done, do the following actions.
    (1) Before the first flight of each day after February 20, 2008 
(the effective date of this AD) until the replacement required in 
paragraph (f)(3) of this AD is done, inspect all plastic connectors 
in the area of the fuel pumps and the connection point of the 
pressure lines to the fuel shut-off valve (behind the rear bulkhead 
of the front fuselage) for possible leakage. Do the inspection 
following STEMME F & D Service Bulletin A31-10-082, Am.-Index: 01.a, 
dated November 30, 2007.
    (2) Before further flight after the inspection required in 
paragraph (f)(1) of this AD, replace the plastic T- and Y-connectors 
in the fuel system with metal connectors if leaks are found. Do the 
replacements following STEMME F & D Service Bulletin A31-10-082, 
Am.-Index: 01.a, dated November 30, 2007. This replacement 
terminates the repetitive inspections required in paragraph (f)(1) 
of this AD.
    (3) Within the next 30 days after February 20, 2008 (the 
effective date of this AD), replace all plastic T- and Y-connectors 
in the fuel system with metal connectors. Do the replacements 
following STEMME F & D Service Bulletin A31-10-082, Am.-Index: 01.a, 
dated November 30, 2007. This replacement terminates the repetitive 
inspections required in paragraph (f)(1) of this AD.
