Federal Aviation Administration (FAA), DOT.
Final rule; request for comments.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) Start Printed Page 893issued 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:
During certification works it was found that the cooling liquid EVANS NPG+ is flammable. The liquid cooling circuit of the Stemme S10-VT is not designed to be filled with a flammable liquid without prior modifications.
This AD requires actions that are intended to address the unsafe condition described in the MCAI.
This AD becomes effective January 29, 2007.
The Director of the Federal Register approved the incorporation by reference of Stemme F&D Service Bulletin A31-10-076 Am. Index: 01.a, dated October 9, 2006, listed in this AD as of January 29, 2007.
We must receive comments on this AD by February 8, 2007.

Streamlined Issuance of AD
The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. The streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products.
This AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The AD contains text copied from the MCAI and for this reason might not follow our plain language principles.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2006-0311-E, dated October 11, 2006 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states that:
During certification works it was found that the cooling liquid EVANS NPG+ is flammable. The liquid cooling circuit of the Stemme S10-VT is not designed to be filled with a flammable liquid without prior modifications. For that reason, this Emergency AD requires the replacement of the EVANS NPG+ cooling liquid. In addition, the operation limit of the cylinder head temperature must be temporary changed to 120°C/248°F.
You may obtain further information by examining the MCAI in the AD docket.
Relevant Service Information
Stemme GmbH & Co. KG has issued Stemme F&D Service Bulletin A31-10-076 Am. Index: 01.a, dated October 9, 2006. 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 the cooling liquid is flammable. The liquid cooling circuit of the Stemme S10-VT is not designed to be filled with a flammable liquid without prior modifications, and this could result in a fire. 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.
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-2006-26518; Directorate Identifier 2006-CE-84-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://dms.dot.gov, including any personal information you provide. We will also post a report summarizing each Start Printed Page 894substantive 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.
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 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.Start List of Subjects

1. The authority citation for part 39 continues to read as follows:End Amendment Part
2. The FAA amends § 39.13 by adding the following new AD:End Amendment Part
2007-01-03 Stemme GMBH & Co. KG: Amendment 39-14874; Docket No. FAA-2006-26518; Directorate Identifier 2006-CE-84-AD.
(a) This airworthiness directive (AD) becomes effective January 29, 2007.
(c) This AD applies to Model S10-VT gliders, serial numbers 11-001 through 11-104, certificated in any category.
(d) The mandatory continuing airworthiness information (MCAI) states that:
During certification works it was found that the cooling liquid EVANS NPG+ is flammable. The liquid cooling circuit of the Stemme S10-VT is not designed to be filled with a flammable liquid without prior modifications. For that reason, this Emergency AD requires the replacement of the EVANS NPG+ cooling liquid. In addition, the operation limit of the cylinder head temperature must be temporary changed to 120 °C/248 °F.
Actions and Compliance
(e) Prior to further flight as of January 29, 2007 (the effective date of this AD), unless already done, do the following actions.
(1) Replace the EVANS NPG+ cooling liquid in accordance with the instructions of Stemme F&D Service Bulletin A31-10-076 Am. Index: 01.a, dated October 9, 2006;
(2) Amend the Limitations and Normal Procedures Sections of the Airplane Flight Manual (AFM) to include the temporary operation limit of the cylinder head temperature to 120 °C/248 °F. This may be accomplished by inserting a copy of this AD into the AFM, affecting pages 2-3, 2-6, and 4-12;
(3) Apply two red lines on the Cylinder Head Temperature Gauge for the L/H and R/H cylinder head temperature at 120 °C/248 °F; and
(4) Replace the radiator cap part number 922075 (0.9 bar/13 psi) (or FAA approved equivalent) with a new radiator cap part number 922070 (1.2 bar/18 psi) (or FAA approved equivalent). Rotax Aircraft Engines Service Instruction SI-25-1997 R8 and Rotax Service Bulletin Sb-914-029 R2 reference this requirement.
