AD 2012-01-02 77 FR 1624

We are adopting a new airworthiness directive (AD) for Schempp-Hirth Flugzeugbau GmbH Model Discus 2cT gliders. 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 small cracks which have been found on engine pylons in the area of the lower engine support that have not been detected during the standard daily inspection. This condition, if not detected and corrected, could lead to an engine pylon failure resulting in loss of control of the glider. We are issuing this AD to require actions to address the unsafe condition on these products.
