Appr. 4.2
Issue III
4.1 Introduction.
Section 4 provides the procedures for the conduct of normal operation. Normal procedures associated
with optional equipment can be found in Section 9.
4.2 Rigging and de-rigging.
Four persons, having the basic technical skill, are necessary to perform the glider de-rigging after an off-
field landing. Before starting the de-rigging of each set, all participants should be informed in details
on the procedures to be done.
Tools necessary:

open ended spanner 17 [mm]

pliers

assembly wrench (steel rod 15 dia x 400 [mm]) with duralumin end for alignment of main fittings
(supplied with glider)
The de-rigged assemblies preferably should be stored directly on the trailer. In case a trailer is not at
hand, the wings and tailplane may by temporarily laid on a grass for a short time, after ensuring no
protruding stones or other hard objects are present.
DO NOT PLACE THE BOLTS AND SCREWS IN CONTACT WITH THE GROUND.
Assemblies should be de-rigged in the sequence as follows.
4.2.1 De-rigging the tailplane.
Two persons are necessary for tailplane de-rigging.

The glider is supported on the wing.

Set the trimming device spring back onto a stop, stick free, rudder deflected sidewards.

Remove the safety pin, undo the nut and take out the main bolt of tailplane (at the nose portion of
stabilizer in its plane of symmetry).

Push the stabilizer backwards at the leading edge until the stabilizer front fitting disengages from
the sleeves. Then, holding the stabilizer on both sides and allowing both elevators to drop down shift
the tailplane backwards. The control system disconnects automatically.

Insert the main bolt back into the fittings in fuselage, screw on the nut initially and insert the safety
pin (to protect against loss).

Put the stabilizer on the trailer, or other suitable location.
