AD NUMBER: 2006-19-08
SUBJECT: Airworthiness Directive 2006-19-08 SUMMARY: 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.
