4. Removing the wings
1. Unlock the airbrakes from the cockpit
2. Set the flap handle in Position 2 or Position 3 and move the control
stick to the centre position.
3. If bug wipers are fitted, release both wipers by approximately
1.5 meters and place them in a safe place while de-rigging the
sailplane. This allows the retrieve cable sleeves to be moved
temporarily out of the way while removing the main pins.
4. For JS-MD 1C, pull wingtip locking lever fully back and slide wing-
wingtips out of the inboard section. Secure the wingtips in the
trailer.
5. Insert the tip rigging handle in the tip spar box.
6. Lift the wings at the tips until the main pins can rotate. Rotate the
wing pins out of the locked position while pulling back the lock pin.
7. Remove the main pins.
CAUTION
: Do not lower the wings after the main pins have been
removed. The fuselage shell may be damaged if the
correct angle is not maintained.
8. Pull the left wing out of the fuselage spar box – secure the wing in
the trailer
9. Pull the right wing out of the fuselage spar area – secure the wing
in the trailer
10. Lock both airbrakes, using the JS Airbrake lock tool.
11. Carefully wind the bug wipers (if fitted) back into the wiper-garages,
while maintaining slight tension on the retrieve cable.
12. Push the fuselage into the trailer
NOTE
:
To avoid loading the airbrake caps, do not leave the
airbrakes locked on the ground (either rigged or de-
rigged). The airbrake locking tool can be used for
temporarily locking the airbrakes for maintenance or
transportation, and the airbrakes should be unlocked
once maintenance or transportation is complete
