SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2017-0911; Product Identifier 2017-CE-025-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to http://regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2017-0136, dated July 31, 2017 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states: Occurrences were reported of finding cracks on exhaust silencer part number (P/N) 800.65.0001, installed on ASK 21 Mi powered sailplanes. Subsequent investigation determined that the affected part is susceptible to fatigue cracking and is also installed on other Schleicher powered sailplanes. This condition, if not corrected, could lead to heat damage in the engine compartment and to the engine installation, possibly resulting in reduced control of the powered sailplane. To address this potentially unsafe condition, Schleicher issued Technical Note (TN) ASK 21 Mi No. 11, TN ASW 22 BLE 50R No. 16, TN ASH 25 M/Mi No. 32 and TN ASH 26 E No. 19 (single document, hereafter referred to as `the TN' in this [EASA] AD), to provide replacement instructions. For the reasons described above, this [EASA] AD requires replacement of the affected exhaust silencer with an improved part and introduces installation restrictions of a part with P/N 800.65.0001. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-0911. Related Service Information Under 1 CFR Part 51 Alexander Schleicher GmbH & Co. Segelflugzeugbau has issued ASK 21 Mi Technical Note No. 11, ASW 22 BLE 50R Technical Note No. 16, ASH 25 M/Mi Technical Note No. 32, ASH 26 E Technical Note No. 19 (single document), dated January 8, 2016. The service information describes procedures for replacing the exhaust silencer with an improved part. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this NPRM. FAA's Determination and Requirements of the Proposed 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 proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance We estimate that this proposed AD will affect 35 products of U.S. registry. We also estimate that it would take about 8 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $3,900 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $160,300, or $4,580 per product. We have no way of determining the number of products that have an affected exhaust silencer, part number 800.65.0001, installed that would need to be replaced. Therefore, this cost estimate includes all affected gliders on the U.S. registry. 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to small airplanes, gliders, and domestic business jet transport airplanes to the Director of the Policy and Innovation Division. Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: (1) Is not a ``significant regulatory action'' under Executive Order 12866, (2) Is not a ``significant rule'' under the DOT Regulatory Policies and [[Page 44363]] 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. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1.
