## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Alexander Schleicher GmbH & Co. Segelflugzeugbau Model ASW-15 gliders. This 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 identifies the unsafe condition as wing root damage. This AD requires repetitively inspecting the wing root ribs for cracks, looseness, and damage and replacing any root rib with a crack, a loose rib or lift pin bushing, or any damage. The FAA is issuing this AD to address the unsafe condition on these products.
