This evening I
continued to work on making the changes called out in section 42D. I attached the template to the forward left
upper section of the firewall and drilled the 4-holes indicated. Next I attached the template to the top of
the tailcone and drilled the holes for the ADAHRS mounting brackets.
I prepped, primed,
installed nutplates and then riveted in the instrument stack support angles and
the com support angles to the instrument shelf.
I also drilled the F-1203A and F-1202F bulkheads and installed the snap
bushings. I also drilled and installed
the snap bushing in the F-1207D-L bulkhead channel. I bought a new angle drill because the only
way I could drill the hole would be to remove the AP servo. I was unwilling to do that so I now own an
angle drill.
I then prepped and
primed the ADAHRS brackets before
installing them in the tailcone. After
priming I clecoed them in place and then riveted them in.
I then turned my
attention to the existing D-sub connectors and the wiring on top of the
instrument shelf. I also decided to
remove the AP-74 auto pilot D-sub connector and associated wiring. I cut off the wires just after the heat
shrink on the optional D-sub connector and put a small piece of heat shrink on
each wire. I then put heat shrink over
the bundle. Next I decided to install
the AP disconnect switch I left out because I knew I would be changing the
center panel with the Sky View update.
It was simple enough to install.
Next I pulled the wires to the Main and Optional D-subs through the snap
bushings in the instrument shelf. What a
tangled mess of wires there is below the shelf now. I will have to get them pulled into the
tunnel and then form a large loop and wire tie them together.
I continued to clean-up the wires on the instrument
shelf. I put labels on the Tunnel and Optional
D-sub connectors. I also attached the
Xpndr Ant cable extension. I am ready to
continue with the installation of the conversion harnesses.
