Airworthiness Directives; DG Flugzeugbau GmbH Model DG-800B Sailplanes

This amendment adopts a new airworthiness directive (AD) that applies to certain DG Flugzeugbau (DG Flugzeugbau) GmbH Model DG 800B sailplanes. This AD requires you to measure and correct improper propeller drive belt tension. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the Federal Republic of Germany. The actions specified in this AD are intended to correct improper drive belt tension and consequent engine crankshaft or connecting rod bearing damage. Such damage could result in loss of propulsion during critical phases of flight.
