Summary
We propose to adopt a new airworthiness directive (AD) for all DG Flugzeugbau GmbH Model DG-1000S sailplanes. This proposed AD would require you to modify the elevator control at the stabilizer assembly, replace a placard on the fin, and incorporate changes in the FAA- approved sailplane flight manual. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are proposing this AD to prevent the rigging of the horizontal stabilizer without properly connecting the elevator, which, if not prevented, could lead to an inoperative elevator.
