antenna cables. Remove the three wing access attach hole
covers. Support the wing tip and proceed to remove the three
main wing attach bolts. To remove the two outboard bolts use
the ratchet on the wing side and the breaker bar in the lower
spar hole. The single inboard bolts access is from inside the
cowling area in the wing root. Access to the nut for this bolt is
from inside the center section spar accessible from inside the
back cockpit.
CAUTION
Be sure the nose is weighted / ballasted so the aircraft will not to
fall over backwards while you are working in the rear cockpit,
especially after the canard is removed.
When the three main wing attach nuts are removed, support the
wing at the tip and root, and slide it aft, off the aircraft. Note the
number and position of each incident (or sweep) shim washer on
each bolt. These shims control the incidence (or sweep) of the
wings and should be replaced exactly as they came off. If the
bolts are also removed, label them (they are different lengths)
and note the number of washers under each head. Set the wing
on foam blocks or padded sawhorses to protect the surface from
damage. The procedure is the same for both wings.
Wing Installation
To install the wings, use the reverse of the sequence explained
above. Be sure the nose is weighted/ballasted so the weight of
the wings won't tip the aircraft over on its tail. Recheck for the
correct number of incidence shims on each bolt. Torque the bolts
to between 150 and 200 in.-lbs. Since you cannot get a torque
wrench in the access wells, it's acceptable to just estimate the
torque. These bolts are not highly stressed in application
(contrary to normal wing attach bolts) and accurate torque is not
required - just snug them up. Be sure that at least two threads
show outside each locknut. Be sure to hook up and run a
complete operational check of the ailerons, rudders, and lighting
prior to flight.
