The spar butt junction wrench must be locked in one
of the notches provided for the purpose and pinned.
CAUTION: Take precautions to prevent jamming the aileron, flap and spoiler
connections during mating of the wings to the fuselage.
After the wings have been secured in place, connect the
control couplings are quick-release, ball-pin type and
must be locked with safety pins.

6.2.1.2. HORIZONTAL TAil MOUNTING
The horizontal stabilizer can be in three positions:
1. Completely dismounted
2. Folded along the fin
3. Mounted in the flight position.
To mount the horizontal tail assembly (Fig 6-3) from
the folded position, raise the stabilizer tips until
their butt fittings match between the double fittings
on the fin. Insert one of the locking pins.
When the stabilizers are near the horizontal position,
take care that the special T-shaped fitting on the elevator
pushrod (behind the fin) couples properly with both
elevators. If the coupling is correct, no abnormal ---­
resistances are met when raising the stabilizers and
after inserting the locking pin; the elevator must operate
normally and smoothly.
WARNING: Do NOT force
the stab; 1izers.
