Airworthiness Directive · Amendment 39-11222 · Stemme GmbH & Co. KG Model S10-VT Sailplanes
Stemme GmbH & Co. KG Model S10-VT Sailplanes
Model S10-VT sailplanes, serial numbers 11-004 through 11-006 and 11-008 through 11-013, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that applies to certain Stemme GmbH & Co. KG (Stemme) Model S10-VT sailplanes. This AD requires modifying the wastegate control in order to eliminate heat damage. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to prevent the wastegate control from malfunctioning because of heat damage, which could result in loss of automatic manifold pressure control and engine damage.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
