ELEVATOR CONTROL IN THE VERTICAL FIN
In one DG-500 the push rod guide of the elevator control rod came loose in the mid-point of the vertical fin. If the guide slips up or downwards this may cause hard movement of the elevator control. The reason that the guide may come loose is a very high compressive load on the foam core in its stand. To prevent from this problem the foam core must be stiffened using epoxy resin thickened with cottonflocks. This AD is applicable to the DG-500/22 ELAN, DG-500 ELAN ORION, DG-500 ELAN Trainer, DG-500/20 ELAN, all serial numbers up to 5E203. DG Flugzeugbau Technical Note No. 348/12 and 843/12 (powered variants), Working Instruction No. 1 for TN 348/12 (843/12) and Drawing 5L36. All documents are attached and herewith become part of this AD.
