Introduction

This Special Airworthiness Information Bulletin advises you, owners and operators of DG Flugzeugbau (Glaser-Dirks) Models DG-100, DG-200, DG-300, DG-400: all serial numbers (S/Ns); DG-500 and DG-500M: all S/Ns up to 5E23; DG-600, and DG-600M: all S/Ns; to implement DG Technical Notes: 301/23 Issue 2, 323/14 Issue 2, 348/18 Issue 2, 359/21 Issue 2, 370/9 Issue 2, 826/44 Issue 2, 843/21 Issue 2, and 866/10 Issue 2 (attached). These Technical Notes require an inspection of the outer bearing ring in the rudder mounting assembly and modification or exchange of the rudder bearing mounting assembly.

Background

On a DG-100, the universal bearing of the rudder lower mounting bracket slipped out of the bearing support causing the rudder to fall out. This condition may exist on the above- mentioned models.

Recommendation

We recommend that you do the actions of the stated Technical Notes upon receipt of this bulletin. We recommend that a certified mechanic check the position of the outer bearing ring daily during pre-flight inspection until the modification or exchange is done. For Further Information Contact
