Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to all Stemme GmbH & Co. KG (Stemme) Models S10 and S10-V sailplanes. This proposed AD would require you to modify the engine compartment fuel and oil system and firewall. This proposed AD is the result of FAA's determination that the actions required in AD 2002-22-04 should also be accomplished on other sailplanes of similar type design. The actions specified by this proposed AD are intended to reduce the potential for a fire to ignite in the engine compartment and to increase the containment of an engine fire in the engine compartment. A fire in the engine compartment could lead to loss of control of the sailplane.
