Airworthiness Directives; Diamond Aircraft Industries Models HK 36 TTS and HK 36 TTC Sailplanes

This amendment adopts a new airworthiness directive (AD) that applies to certain Diamond Aircraft Industries (Diamond) Models HK 36 TTS and HK 36 TTC sailplanes. This AD requires inspecting the engine turbocharger oil-pressure line for the correct banjo bolt. The correct banjo bolt will have a valve seat, instead of a built-in orifice. If the banjo bolt does not have a valve seat, then this action will require replacing the banjo bolt with one that has a valve seat, and repairing or replacing the turbocharger. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Austria. The actions specified by this AD are intended to prevent possible loss of engine power, which could result in possible loss of control of the sailplane.
