Wings rigging
Rigging of the wings to the fuselage is to be done with disassembled wingtips.
Sequence of operations in rigging:
1. Put the assembly key (21) through the guide (19) and screw it into locking pin
(18), causing falling outward of locking claws (17), and then with the same
assembly key remove locking pins from wing rear fittings.
2. Insert the root of RH spar into fuselage, aligning pins (3) and (16) with fitting
sleeves (4) and (14). In parallel, bring the terminals on torque tubes of aileron
control (5) and airbrake control (6) to enter latch pins (7) and (8) in root rib of RH
wing panel.
3. Insert the root of LH wing into fuselage. Manoeuvre with wing tips so to align the
pins (3) and (16) and corresponding sleeves (4) and (14), and insert the conical
portion of pins (1) in the sleeves (2).
4. Pull the spar roots to each other by means of special mounting wrench (12). In
case of jamming over the final phase of movement, align the torque tubes
terminals (5) and (6) with latch pins (7) and (8) by movements of the control stick
and airbrake control pushrod.
5. Connect the spar roots with the main bolt (10), inserting simultaneously the bolt in
the ball socket (9) fastened in the frame.
6. Lock the fuselage rear pins (16) by means of locking pins (18) with the assembly
key (21) screwed in, inserting them through guides (19). Screw out the assembly
key ‒ in the final stage of screwing out (2 coils) check the efficiency of pin
protection against protruding. In addition, visually check through the guide hole if
locking claws (17) are blocking the locking pin
– view “W”.
7. Secure the main bolt (10), connecting the handle of main bolt (11) with fuselage
frame by means of safety pin (13).
8. Secure the wing front pins (3) by means of cotter pins (20).
Connection of control systems at the wing/fuselage junction is accomplished
automatically. During operation of wing/fuselage rigging process the terminals of
torque tubes in aileron (5) and airbrake (6) control systems are aligned with
corresponding rotary latch pins (7) and (8) of controls mounted in wing root ribs.
Connecting the spar roots with main bolt (10) ensures adequate protection of control
systems against disconnection.
2.1.3.
Wings de-rigging
Disassemble wingtips before de-rigging wings from fuselage.
De-rigging is to be made in reverse sequence.
To remove the main bolt (10), move the wing tips up and down. Disconnection
of controls at wing/fuselage junction occurs automatically.
