SECTION 12 - WING RIGGING AND DE-RIGGING, FLYING WITH DOORS REMOVED
12.1. Attaching the wings to the folding mechanism. (Optional).
The C-42 has an optional folding wing which minimises hangar space. For road transport
however you must remove the wings completely. To attach the wings to the folding system:
Step 1. Fit the jockey wheel to the stern post, fit the traingular wooden support brackets to the
bottom of the tailplane struts, with the aluminium strip uppermost.
Step 2. Remove the stop ring from the slide tube in the cockpit roof.
Step 3. Place a wing parallel to the fuselage with its tip supported on the tail by the wooden
support bracket.
(With both wings folded back and supported by the tail, the aircraft will rock back to sit
on its tail. With only one wing on the tail, the aircraft can be tipped forward to a stable
attitude resting on its nose wheel. Be aware of these movements during rigging and
derigging operations. Take care to protect the wing from damage by contact with the
ground).
Step 4. Lift the wing root and slide the attachment block (roller) 2 inches (5cm) over the slide
tube.
Step 5. Attach the stop cable on the leading edge to the quick link on the slide tube.
Step 6. Attach the stop ring to the end of the slide tube.
If both wings are in the folded back position the C42 can be easily moved by one person
into a small hangar space.
12.2 Rigging the wings
If you are tall but weak, it may be easier to manipulate the wing during rigging by holding it at its
tip. If you are short and strong, the better handling point is the top of the wing struts. If you are
short and weak, fetch a friend. If you are short, weak and friendless, don't derig.
Before attempting rigging, take a look at the wing roots and the way in which the rigging
mechanism works. Note that the fulcrum (the roller bracket) is located near the wing root, and
also in line with the rear spar attachment point. The front spar attachment point however is
located some way inboard. This means that lifting the wing tip will result in the front spar clearing
its fitting before the rear one. This can be used to advantage during rigging.
Step 1. Ensure that the spar channels in the cockpit roof are aligned with the top surface of the
cockpit roof frame. Lock the controls, place the flap lever in the fully up position and
ensure the brake is on.
Step 2. Bring the left wing strut into its correct position on the left wing and attach the auxiliary
(jury) struts on the front and rear wing struts to the leading and trailing edge fittings.
Step 3. If this is the first side to be rigged and the second wing half is still resting on the tail, lift the
wing at its tip with one hand. With the other hand, steadily lift the tail so that the aircraft
rests on its nosewheel.
Step 4. Carry the wing into its 90° position relative to the fuselage, taking care not to damage
the door and fuselage with the front spar.
Step 5. Turn the wing into a horizontal position and push it gently towards the fuselage.
Step 6. Lifting the tip, slowly insert the wing roots into position in their channels, leading edge first.
