Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Stemme GmbH & Co. KG (Stemme) Model S10-VT 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 mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this proposed AD are intended to reduce the potential for a fire to ignite in the engine compartment and 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.
