[Federal Register Volume 82, Number 101 (Friday, May 26, 2017)] [Rules and Regulations] [Pages 24239-24241] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-10402] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2017-0451; Directorate Identifier 2017-CE-015-AD; Amendment 39-18885; AD 2017-10-11] RIN 2120-AA64 Airworthiness Directives; Stemme AG Gliders AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule; request for comments. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for Stemme AG Model S10-VT gliders (type certificate previously held by Stemme GmbH & Co. KG). 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 certain propeller front transmission gear wheels having insufficient material strength because of improper heat treatment [[Page 24240]] during manufacturing. We are issuing this AD to require actions to address the unsafe condition on these products. DATES: This AD is effective June 15, 2017. We must receive comments on this AD by July 10, 2017. ADDRESSES: You may send comments by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments. Fax: (202) 493-2251. Mail: U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590. Hand Delivery: U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. Examining the AD Docket You may examine the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017- 0451; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. FOR FURTHER INFORMATION CONTACT: Jim Rutherford, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4165; fax: (816) 329-4090; email: [email protected]. 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. 2017-0072-E, dated April 26, 2017 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states: It has been determined that, following improper heat treatment during manufacture, the material strength of an identified batch of propeller front transmission gear wheels is insufficient. This condition, if not corrected, can lead to failure of a gear wheel, with possible loss of the power transmission between the engine and the propeller and, eventually, reduced control of the sailplane. Prompted by these determinations, Stemme issued Service Bulletin (SB) P062-980010, providing instructions not to operate sailplanes equipped with affected parts. For the reasons described above, this [EASA] AD requires replacement of affected gearboxes. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017- 0451. 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 improper heat treatment of the propeller front transmission gear wheels could cause the gear wheel to fail. This failure could cause loss of power between the engine and the propeller, which could result in reduced control. 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-2017-0451; Directorate Identifier 2017-CE-015-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 There are approximately 50 Stemme AG Model S10-VT gliders of U.S. registry but only 14 serial numbers of the part number (P/N) 11AG front gearbox. Therefore, the most gliders of U.S. registry affected would be 14. According to Stemme AG, there are only 2 of the affected gearboxes installed on gliders of U.S. registery. At the issue date of this AD, no design solution is available to restore the airworthiness of the respective type design to a level corresponding to its approved type design specifications. Therefore, the FAA cannot determine the cost of returning the affected gliders to service. 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, [[Page 24241]] (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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment 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: 2017-10-11 Stemme AG: Amendment 39-18885; Docket No. FAA-2017-0451; Directorate Identifier 2017-CE-015-AD. (a) Effective Date This airworthiness directive (AD) becomes effective June 15, 2017. (b) Affected ADs None.

(d) Subject Air Transport Association of America (ATA) Code 61: Propellers/ Propulsors. (e) Reason This AD was prompted by 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 certain propeller front transmission gear wheels having insufficient material strength because of improper heat treatment during manufacturing. We are issuing this AD to prevent failure of the propeller front transmission gear wheels. This failure could cause loss of power between the engine and the propeller, which could result in reduced control. (f) Actions and Compliance Unless already done, do the following actions. (1) Before further flight after June 15, 2017 (the effective date of this AD), replace the front gearbox following a method approved specifically for this AD by the FAA, Small Airplane Directorate. Contact the FAA using the information in paragraph (g)(1) of this AD to obtain FAA-approved repair instructions approved specifically for compliance with this AD and incorporate those instructions. Note 2 to paragraph (f)(1) of this AD: At the issue date of this AD, no design solution is available to restore the airworthiness of the respective type design to a level corresponding to its approved type design specifications. (2) As of June 15, 2017 (the effective date of this AD), do not install a front gear box listed in paragraph (c) of this AD. (g) Other FAA AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
