AD 2006-24-06 Airworthiness Directives; Stemme GmbH & Co. AG Model STEMME S10-VT Sailplanes

This AD applies to STEMME Model S10-VT sailplanes; certificated in any U.S. category: (1) Serial numbers (S/Ns) 11-89 through 11-096; and (2) All S/Ns where pressure lines were replaced between July 27, 2004, and June 22, 2005, inclusive, and the parts were provided by Stemme Gmbh & Co. AG (Stemme). Reason (d) The mandatory continuing airworthiness information (MCAI) states that ripped pressure lines betweeen Airbox-Carburator-Differential fuel pressure sensor were found during a requested maintenance event after engine trouble in the range between maximum continuous power and take off power. The cracks can be a result of non complete temperature resistance. This type of pressure line was installed since July 27, 2004. It was used for serial production and spare parts.

Unless already done, do the following actions. (1) Within 30 days after the effective date of this AD, inspect all 0.15 - 0.27 inch (4 x 7mm) pressure lines for porousness or cracks in particular areas of T-splits parts, clamps, or connections. The free areas between the white plastic covers must also be checked. If cracks or porosity are found, before further flight, replace all pressure lines with ROTAX part number (P/N) 860 660 or Stemme P/N HZ-KLS041 (or FAA-approved equivalent P/Ns) pressure lines following STEMME F&D Design Org. Service Bulletin A31-10-73, Am. Index 01.a, dated June 22, 2005. Within 60 days after the effective date of this AD, unless already done, replace all installed 0.15 x 0.27 inch (4 x 7 mm) pressure lines with ROTAX P/N 860 660 or Stemme P/N HZ-KLS041 (or FAA-approved equivalent P/Ns) pressure lines following STEMME F&D Design Org.
