Abstract
We are adopting a new airworthiness directive (AD) for all Burkhart GROB Luft- und Raumfahrt GmbH Models GROB G 109 and GROB G 109B powered sailplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 excessive corrosion on the nose plate in the vertical stabilizer, which could cause the vertical stabilizer nose plate to fail. We are issuing this AD to require actions to address the unsafe condition on these products.
