Summary
We propose to adopt a new airworthiness directive (AD) for all Alexander Schleicher GmbH & Co. Segelflugzeugbau Models ASH 25M and ASH 26E 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 fatigue cracks found on the exhaust silencer. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
