AD 2013-03-09 78 FR 9792

We are adopting a new airworthiness directive (AD) for DG Flugzeugbau GmbH Model DG-1000T gliders equipped with Solo Kleinmotoren Model 2350 C engines. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a material defect of the propeller shaft, most likely caused by a manufacturing error. We are issuing this AD to require actions to address the unsafe condition on these products.
