AD 2007-15-03 Airworthiness Directives; Stemme GmbH & Co. KG Model S10-V and S10-VT Powered Sailplanes

This AD applies to Models STEMME S10-V and STEMME S10-VT powered sailplanes, all serial numbers, that: (1) Are certificated in any category; and (2) Have not incorporated the actions in their entirety of STEMME F & D SB A31-10-078, Am.-index: 01.a, dated November 6, 2006, which references STEMME F & D Installation Instruction A34-10-078-E, Am.-index: 01.a, dated February 20, 2007.

Unless already done, within the next 25 engine operating hours after August 28, 2007 (the effective date of this AD) or 90 days after August 28, 2007 (the effective date of this AD), whichever occurs first, do the following actions: (1) Replace the blade follower type 10AP-VM with the new type 10AP-VP following the instructions contained in STEMME F & D SB A31-10-078, Am.-index: 02.a, dated March 2, 2007, which references STEMME F & D Installation Instruction A34-10-078-E, Am.-index: 01.a, dated February 20, 2007. (2) As of 25 engine operating hours after August 28, 2007 (the effective date of this AD) or 90 days after August 28, 2007 (the effective date of this AD), whichever occurs first, do not install a propeller type 10AP-F, 10AP-V or 11AP-V on any aircraft, unless that propeller has the new type 10AP-VP blade follower installed following the instructions contained in STEMME F & D SB A31-10-078, Am.-index: 02.a, dated March 2, 2007, which references STEMME F & D Installation Instruction A34-10-078-E, Am.-index: 01.a, dated February 20, 2007. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: The MCAI requires an amendment to the aircraft flight manual before further flight as an interim requirement to the replacement. We consider before flight as an urgent safety of flight compliance time, and we do not consider this unsafe condition to be an urgent safety of flight condition. We feel that 25 engine operating hours or 90 days, whichever occurs first, for the replacement is an adequate compliance for this AD action. We do encourage you to incorporate these flight manual amendments referenced in the MCAI and service information until you replace the propeller blade follower. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Staff, FAA, ATTN: Gregory Davison, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri, 64106; telephone: (816) 329-4130; fax: (816) 329-4090, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et. seq. ), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
