❑ Use a large Perma-Grit file to adjust the slot in the fuse end rib to easily accept the CF
tongue. If rib doubler needs more work use a 3/32" carbide rotary cutter.
❑ Chamfer the ends of the (4) 4-40x1" bolts to ease alignment and starting of thread.
❑
Apply a 4-40 nut to bolt, spin end against a grinding wheel then remove nut to clear
threads.
❑ Drill clearance hole (1/8") in ply above the
flex plate to accept the 4-40 bolt.
❑ Install the tongue into wing panel, leave
screw loose.
❑ Assemble wing onto fuse without the
boom to test fit of CF tongue into the fuse
rib. Adjust slot as necessary for an easy
fit.
NOTE: A slight gap of 1/8" between wing
panel and boom may occur. This gap can
be minimized by applying pressure on
wing panel against boom, while drilling
the hole through flex plate and CF
tongue. Have a helper hold wing, boom
and fuse as tightly together as possible
while drilling the #43 hole in the CF
tongue.
❑ Remove wing, slide boom into position,
then wing and hold tightly against boom.
Block sand the inboard end of flaps as
necessary for the wing to fit up against the
boom. Trim flap per photo on pg.26 if
necessary.
❑ Check also F/G flanges at wing root for
interference. Drill through the hole in the
flex plate and through the CF tongue with
a #43 (.089") bit, then 4-40 tap the hole in
tongue. Chamfer end of 4-40x1" SHCS
and install. Tighten both bolts for flight. To
remove wing panel, loosen the outboard
bolt and remove the inner one.
