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 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.
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.

Adoption of the Amendment
0 Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0 1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0 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.
