Task: Finished F-741 tunnel support, installed
static line, and started flap mechanism
day today! My fiance had to work all day so I used the time
to work on the project. We got a lot done! I started the morning
off by drilling the F-741B tunner cover. I had previously
drawn it in AutoCad, hoping it would make drilling the holes
easier. However I had no way of ensuring everything was lined
up square, so ended up scribing lines the old fashoned way
(with a marker and set of calipers).

I had not yet made the bend on the left side (as shown in
we clamped the F-741A supports in placed and match drilled
with the lower #19 holes in the inboard seat ribs/seat floors.
This wasn't ideal as I should have pre-drilled the holes before
I cut all the angles on the supports. Once the supports were
in place, we clamped the tunnel cover on the supports and
climbed in the back of the fuselage and installed the static
line along the F-708 bulkhead. I attached a "T"
fitting to the left side and temporarily ran hose to the front
of the aircraft. I found that I didn't like how high the "T"
fitting was as it was causing the static line to hit the bolts
on the shoulder harness attach mount.
I've clamped several of the static line clips in place to
Next we begun installing the F-782 center cabin cover. This
assembly has several pieces to it, some of which we don't
yet have. First we measured and clamped the heat baffle plate
in place to be drilled.
Once the heat baffle was clecod in place we inserted the firewall
recess again and then placed the F-782C in place between the
two center floor stiffeners. The F-983C fuel valve cover was
then screwed to the F-783 cover support ribs so we could drill
the lower 2 holes in the F-782C with the F-983C.
Lastly we tackled the electric flap assembly. Shown is the
flap motor assembly with the worm drive actuator attachment
We fabricated several parts (F-767, F-766B and F-766C) per
the plans and then installed the actuator/motor assembly in
We then mounted the assembly to the floor and F-705 channel
to check alignment and fit. Everything fit as it should and
