To de-rig:
proceed in the reverse order of rigging starting with the hori-
zontal tail, winglets, wing tips and inner wings. We would add the follow-
ing suggestions:
1.
Drain all water ballast. To properly do so screw off the cover from
the wing water tank on the upper wing surface and open the valves.
Ensure that all the water has emptied out by putting down alternative
wing tips several times. Despite technical provisions, the wing sur-
faces might suffer from humidity on the long run.
At the wing root there is a drain hole in front of the forward lift pin
bushing. Ensure these holes are open, when wings are put in the
trailer, so that remaining water can spill out. The same applies for
the valves and the openings at the upper wing surface.
2.
If a tail water ballast tank is installed, check if water has gathered in
front of the rudder or inside the fuselage tail cone. If water is found,
check all hose clamps, hoses and valve for leaks.
3.
If the tailplane is very firmly located in its rear seating, it will be more
easily dismantled by pushing it forwards by the tips.
4.
If a battery box according to TN 3 is installed in the baggage com-
partment, then the battery has to be removed before de-rigging the
aircraft. When necessary, also the platform for the clamping lever
can be removed.
