## Summary

We are revising an earlier NPRM for DG Flugzeugbau GmbH DG-500 Elan series sailplanes and Models DG-500M and DG-500MB powered sailplanes. 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 incorrect re-installation of the rear cockpit securing rope for the headrest of the rear seat during maintenance, which could cause the rear seat to interfere with the control stick of the sailplane. We are issuing this proposed AD to require actions to correct the unsafe condition on these products.
