Three people again are needed to disassemble
the wings.
First block all three wheels for the fuselage
to stay in position. Empty both fuel tanks by
opening both fuel valves inside the cockpit
and the drain valve beneath the bottom en-
gine cover. Place a canister under the drain
valve to intercept fuel.
While you wait for the tanks to empty, disas-
semble the horizontal tail surfaces, disconnect
all electrical cables and pitot-static lines. Do
not forget to unscrew the pitot tube on the
bottom side of the right wing. Then, inside the
cockpit, unscrew the middle main spar screw
rst, then unscrew and remove both pin bolts.
WARNING! Do not remove spar pins yet!
Once the fuel tanks are empty, disconnect the
fuel hoses inside the cockpit as well.
Make sure you tape the end attached to the
wing not to spill any eventual leftover fuel over
the fuselage or glass surfaces as substantial
damage may occur.
Two people must now lift the wingtips (one
wingtip each) and the person in the cock-
pit remove the main spar pins, one by one,
smoothly.
Forcing pins out of their position may result
in structural damage, therefore the wingtip
holders must hold the wing-halfs precisely at
certain height!
Using slight circular movement at the wingtip,
the wing-halfs must now be pulled out of the
fuselage slowly. On pulling, each wing-half
must be held by two, one at the wingtip and
one near the spar.
As the wing-halfs have been pulled out, place
them onto a soft surface to prevent their
damage.
