Introduction
This Special Airworthiness Information Bulletin informs you of an
airworthiness concern on all variants of Glaser-Dirks Flugzeugbau Model
DG-100 and DG-200 series sailplanes, all serial numbers, except for the
Model DG-100 sailplanes.
Background
During a pre-flight inspection of a DG-100 sailplane, the rod end of
the aileron control push-rod at the control column was found broken. An
investigation revealed that the broken rod end was made from
inappropriate machining steel. DG Fluzeugbau has issued Technical Note
No. 301/25, 323/16 to establish corrective actions.
The European Aviation Safety Agency (EASA) has issued Emergency
Airworthiness Directive No. 2009-0167-E, dated July 30, 2009. This AD
requires a before-further-flight inspection and possible replacement of
the aileron control rod end.
Recommendations
These sailplanes (except for the Model DG-100) are not type
certificated in the United States and, therefore, the condition is not
addressed by FAA AD action.
We recommend all owners and operators comply with actions outlined in DG Flugzeugbau Technical Note No. 301/25, 323/16.
