## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to Glaser-Dirks Flugzeugbau GmbH (Glaser-Dirks) Model DG-400 gliders. The proposed AD would require replacing the Bosch electrical system regulator, part number (P/N) 0212920001, with a type 4 E 26 regulator. The proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by the proposed AD are intended to prevent failure of the electrical system regulator, which could result in smoke entering the cockpit with consequent passenger injury.
