Notes for Operation - Wing Folding
1. Remove the 2 clevis pins holding the aileron cables to the aileron bellcrank between the seat backs, and remove the 'R' clips and wedge-keepers allowing the cables to be freed from the brackets.
2. Tape - up the flaps (along or across the wing - flap top joint) to prevent them dropping down and damaging the rear window(s) when free.
3. Remove the 2 clevis pins from the flap operating arms above the cabin roof.
4. Remove wing - root cover strips on both top and bottom of each wing. Remove both speed - fairings at each end of each strut.
5. Remove the 5/16" nut and bolt at the TOP end of the STARBOARD strut, and get someone to support the weight at the wingtip when it is free. Lower the strut end to the ground (protect against abrasion) and then lower the wingtip to the ground (protect against abrasion) while checking to ensure that the flap - operating rods are not snagged as the wing tip lowers. Note: The aircraft will be remain stable on undercarriage with one wing removed, but caution must be exercised in strong winds (provide additional support under other wing).
6. Locate wing - attach lever (exposed by wing tip being lowered) and while supporting the rear of the wing at the root end, lift lever until both pins release.
7. Withdraw wing by holding at tip end, tip up 6". Wing leading edge will be supported by s/s tube sliding in bearing in fuselage. Note: this tube and bearing is designed to be a LOOSE fit!
8. Pull end of aileron cable thro' hole in upper cabin roof; this may entail swinging the wingtip FORWARD temporarily to provide sufficient space to withdraw the cable.
9. Lift wing tip sufficiently to allow trailing edge to be lowered without wing root (or flap) fouling fuselage.
10. When wing is vertical (chord-wise), it can be swung carefully aft and stowed as appropriate, i.e. above the tailplane on a suitable structure / dolly.
11. Remove the stall - warning neoprene tube from the port wing - root fitting (access at front / underneath port wing root).
Repeat steps 5 - 10 for PORT wing.
12. Remove pitot tube fitting from neoprene tube at lower end of STARBOARD wing strut, and remove nut / bolt and strut
13. Remove PORT wing strut by removing nut / bolt
Re-fitting of wings is reverse of the above
Note: It is suggested that additional clevis pins and their safety pins are obtained in case of loss while rigging / de-rigging. Also, suggest replacement of 5/16" bolts / nuts with suitable clevis pins and 'safeties' for speed of rigging & de-rigging; (get PFA Inspector approval for this)
IMPORTANT: DO NOT TIGHTEN THE 5/16" STRUT BOLTS!! THEY SHOULD BE TIGHTENED ONLY SUFFICIENTLY TO REMOVE END-PLAY IN THE BOLT, I.E THE WASHERS SHOULD BE JUST MOVABLE WHEN PRODDED WITH A SCREWDRIVER.
