## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to all Glaser-Dirks Flugzeugbau GmbH (DG Flugzeugbau) Models DG-400 and DG-800A sailplanes. This proposed AD would require you to inspect the rear plate of the propeller mount for marks and/or cracks and replace if necessary. This proposed AD would also require you to inspect the mounting blocks for cracks and replace if necessary. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this proposed AD are intended to detect and correct cracks in the propeller mount plate and mounting blocks, which could result in reduced structural integrity of the propeller mounting structure. This could lead to a hazardous flight condition or loss of control of the sailplane.
