## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all

((Page 35028))

DG Flugzeugbau GmbH Models DG-808C and DG-1000T gliders. This proposed AD was prompted by 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 damaged fuel hoses due to environmental and fatigue deterioration. This proposed AD would require inspecting the polyurethane (PU) fuel hoses, replacing the PU fuel hoses if there is damage, and establishing a life limit for the PU fuel hoses. The FAA is proposing this AD to address the unsafe condition on these products.
