AD 2001-05-01 66 FR 14304

This amendment adopts a new airworthiness directive (AD) that applies to certain DG Flugzeugbau GmbH (DG Flugzeugbau) Model DG-500MB sailplanes equipped with a SOLO 2625 02 engine. This AD requires you to install additional access holes in the propeller mount and modify the engine. This AD also requires you to do a ground test run and replace the digital engine indicator circuit breaker. 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 by this AD are intended to correct an inadequate circuit breaker and unsatisfactory drive belt tension that could cause damage to the engine crankshaft. Such damage could lead to engine failure and loss of control of the sailplane.
