2. Flaps should be fully retracted prior to wing fold.
3. Press the small detent clip to release the red wing lock handle and pull down to the stop (90
degrees from stowed/locked position).
4. At wing tip, place one hand on the wing fold handle and the other on the tip trailing edge. Using
a smooth, fluid motion, step away from the aircraft center line pulling the wing away from of the
fuselage until the stop is reached, approximately 21 inches.
NOTE: Pulling the wing away from the fuselage will require lifting the wing
tip and slight vertical motion in order to take the weight off wing
spar mating surface.
5. As wing moves outward, be careful not to drop the wing as structural damage will occur.
6. Rotate wing leading edge up 90 degrees to the vertical position.
NOTE: Due to camber of upper wing surface, bottom of wing will appear to
be vertical while top of wing will appear to be past vertical.
7. Walk the wing aft to the horizontal tail while being careful to keep the wing lower surface aligned
vertically in order to prevent contact with the Seawings™ platform.
8. Approaching the horizontal tail, stop with the wing leading edge directly below the tail pin.
9. Slide wing approximately 21 inches to the stop being careful to keep the wing vertical to maintain
clearance from the Seawings™ platform.
10. Lift the wing tip to connect socket with tail pin, being certain to align leading edge socket with tail
pin.
NOTE: There will be a recognizable and positive sound and feel when the
socket is seated with the tail pin.
11. See wing fold/extend additional information. (See “Wing Fold/Extend Additional Information” on
page 18-6.)
VERIFICATION METHOD:
Verify security of the wing on the horizontal tail latches.
