Abstract
The FAA is adopting a new airworthiness directive (AD) for all Stemme GmbH (Stemme) TSA-M Model S6-RT and Stemme S 12 gliders. This AD was prompted by a report of a leaking electrical fuel transfer pump. This AD requires inspecting affected electrical fuel transfer pumps for certain non-conforming parts, and if found, replacing them with approved parts. This AD also prohibits installation of certain non- conforming parts on affected gliders. The FAA is issuing this AD to address the unsafe condition on these products.
