(b) Secure pins using Fokker-needles.
(c) Install the both forward wing pins using the on-board rigging tool. Insert them against
flight direction. Make sure the safety pin holes are passable.
(d) Secure pins using spring pins.
(4) Reconnect the fuel line quick connectors of the fuel supply and fuel return line.
(5) Reconnect the avionic connector.
(6) Reinstall the cockpit back wall using screws.
(7) Reconnect the pneumatic hoses at the left main frame by means of the quick release
couplings.
(8) Reconnect the control rods by means of the quick connectors (red).
(a) First reconnect the air brake control rod.
(b) Reconnect the flap control rod.
(c) Reconnect the aileron control rod.
(9) Safety pin all rod quick connectors.
B. To rig the outer wings, follow these steps:
(1) Prepare the aircraft as follows:
(a) Make sure the flap control lever in the cockpit is in the “LDG2” position.
(b) Make sure the airbrake control lever is in the most forward position.
(c) At the inner wing side, loose all control rod quick connectors.
(d) Verify the main pins are available, checked for condition and greased as required.
(2) Insert the main pins into the bushings of the inner wing spar using the T-handle tool. Do not
push them through.
CAUTION: PAY ATTENTION TO A CORRECT OUTER WING ALIGNMENT WHILE
SLIDING ITS SPAR INTO THE INNER WING SPAR.
(3) Slide the outer wing spar into the inner wing spar until the distance between wing pieces is
20 cm.
(4) Extend the airbrake. To do this, move the bell crank of the airbrake linkage at the outer wing
by hand and hold simultaneously the airbrake by the other hand.
(5) Slide the outer wing spar into the inner wing spar until the distance between wing pieces is 8
– 10 cm.
WARNING: THE QUICK CONNECTORS SHALL ENGAGE INTO THE CONTROL RODS
FROM ABOVE DOWNWARDS. THE SAFETY PINS SHALL BE INSERTED
AGAINST FLIGHT DIRECTION.
(6) Reconnect the control rods by means of the quick connectors (red).
(a) First reconnect the air brake control rod.
(b) Reconnect the outer aileron control rod.
(c) Reconnect the inner aileron control rod.
(7) Safety pin all rod quick connectors.
(8) Reconnect the avionics connector. Ensure the cable or the connector does not protrude out
the wing contour.
(9) Slide the outer wing spar completely into the inner wing spar. Pay attention to cables and
connectors!
NOTE: The gap between inner and outer wing portions shall be not more than 2 mm.
(10) Push the main pin completely through using the T-handle tool.
NOTE: It may be advisable to lift up the outer wing slightly to assist the insertion of the
main pin. Maybe helpful to rotate the pin axially while pushing it through.
NOTE: The main pin seats correctly if the safety flap at the inner wing can be closed
completely and is flush to the wing contour if the T-handle tool is removed.
(11) Do the steps (1) thru (11) for the other outer wing.
C. To rig the winglets, follow these steps:
(1) Slide the winglet spar into the outer wing spar until the avionics connector can be
reconnected.
(2) Reconnect the avionics connector.
(3) Slide the winglet spar completely into the outer wing spar.
(4) Push the winglet pin completely through using the T-handle tool.
NOTE: The winglet pin seats correctly if it is flush with the wing contour when the T-
handle tool is removed.
D. Installation Test
(1) Inspect visually all gaps between wing pieces for correct condition.
(2) Do an operational test of all flight controls.
(a) Ensure the controls can be moved freely without jamming or abnormal noises.
(b) Ensure the control surface deflection is adequate to the control input.
E. Job Completion
(1) Verify all used tools incl. onboard tools are completely available.
(2) Remove all equipment used for these tasks and return aircraft to its initial condition.
6. Horizontal Tail Rigging Procedure
WARNING: HORIZONTAL TAIL RIGGING MUST BE ACCOMPLISHED BY AUTHORIZED
PERSONNEL ONLY.
CAUTION: ENSURE SUFFICIENT PERSONNEL IS AVAILABLE TO ASSIST.
A. To rig the horizontal tail, follow these steps:
NOTE: The elevator has an automatic control system connector.
(1) At the horizontal tail withdraw the FWD tensioning screw until it stops.
(2) Position the horizontal tail from above downwards. While doing this, it is very important
that the castor of the elevator actuation lever fits into its corresponding fork that is located in
the vertical tail.
(3) Then push the horizontal tail at the leading edge rearwards so its attaching pins slide into the
appropriate bushings of the attachment bracket of the vertical tail.
NOTE: Make sure all three pins fit completely in their bushing,
(4) Tighten the tensioning screw using a ring spanner with a width across flats of 8mm.
