S10 FAA AD Exhaust Inspection

Docket No. FAA-2006-25689; Directorate Identifier 2006-CE-45-AD; Amendment 39-14765; AD 2006-19-08

The FAA is adopting a new airworthiness directive (AD) for certain Stemme GmbH &
Co. KG Model STEMME S10-VT sailplanes. This AD requires you to do a one-time inspection of all exhaust bends (each cylinder 1 to 4) in the area of the curvature bend near the cylinder flange, replace any damaged exhaust pipes found, and recondition the heat protection wrapping. This AD results from deformations and cracks found at an exhaust bend during maintenance work. We are issuing this AD to detect and correct cracks in the exhaust pipes. Damaged exhaust pipes could cause exhaust gases to expand into the engine compartment and/or carbon monoxide (CO) to leak into the cockpit section.
