## Summary

We propose to adopt a new airworthiness directive (AD) for Ballonbau Worner GmbH Models NL-280/STU, NL-380/STU, NL-510/STU, NL-640/STU, NL-840/STU, and NL-1000/STU balloons. 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 current inspection intervals are no longer adequate to ensure timely detection of deterioration or damage. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
