Wing Strut Installation - Horizon Fitness Hangar9 Carbon Cub 15cc Manuel D'utilisation

WING STRUT INSTALLATION

1. Before installing the strut brackets, thread an M3 x 12
socket head screw into each blind nut. If the screw does
not thread in easily, use a 3mm tap to clean the threads
in the blind nut.
2. Attach the strut bracket to the bottom the wing using two
M3 x 12 socket head cap screws for each bracket. Make
sure to use threadlock on each of the screws to prevent
them from vibrating loose.
3. Use a pin vise and 1/8-inch (3 mm) drill bit to remove any
excess paint from the hole in the jury strut mounts.
4. Thread the jury strut mounts into the holes in the wing.
The upper lip of the mount will be fl ush with the bottom
of the wing.
5. Thread the ends on the struts so there is roughly
1/8 inch (3mm) of thread exposed between the end of the
strut and the fi tting. The exact position of the end will be
adjusted when the struts are installed.

6. Measure the distance between the end of the strut and
the jury strut mount. The mounts are not centered on
the strut: the side where the bracket is positioned 12
inches (317mm) from the end of the strut will be the side
that attaches to the bracket.
7. Attach the struts to the brackets using M3 x 12 socket
head cap screws and M3 locknuts.
8. Attach the jury struts to the jury strut mount using M3
x 12 socket head cap screws and M3 locknuts. Attach
the spreader bar to the front and rear struts using M3 x
15 socket head cap screws and M3 locknuts. The strut
bracket and spreader bar are inside the jury strut.
9. Check the positioning of the jury struts and hardware
using the photos 9 and 10.
10. Use a square to check that the jury struts are
perpendicular to the bottom of the wing. If not, the jury
strut mounts on the struts can be repositioned to adjust
the jury struts.
