## Summary

We propose to adopt a new airworthiness directive (AD) for Alexander Schleicher GmbH & Co. Model ASK 21 gliders. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 cable slack in gliders equipped with a rudder hand control system leading to a short-term blockage of the rudder control system and reduced control. We are issuing this proposed AD to correct the unsafe condition on these products.
