4.3.6.1 Adjusting the cable tension of the aileron control system
If the cables are not taut, they must be tightened. The attachment screw of the
aileron quadrant must first be loosened slightly. The eccentric disc can then be
turned by a sharp-edge screwdriver and a small hammer so that the aileron quadrant
axle can be pushed forward in the oblong hole. The tension of the aileron cable is
thus tightened. When the correct tension is reached, the hexagon bolt is tightened.
Cable tension adjustment is done by "feel". The cable should neither sag not be too
tight.

4.3.6.2 Checking the connection of the sliding sleeve with the flap spar
With this connection care must be taken that the flap spar tube positively fits into the
detents of the sliding sleeve without significant play and that the pins of the spring-
loaded locks are completely extended on both sides.
If this is not the case, an IFC / ISC or COMCO IKARUS GmbH must be contacted.
Adjustments may be necessary if wings or wing flaps are
replaced.
