I am currently rebuilding a C172A that was completely disassembled. I am currently installing the control cables (throttle, carb heat, mixture, etc.) and cannot find information as to how these cables are routed from the instrument panel through the firewall. Neither the parts manual or maintenance manual provide that amount of detail. Does anyone have this information or know where it can be obtained?

My main problem is I have not been able to figure out how to route these cables without rubbing against the control column.

Any help will be greatly appreciated.

Jim:
Shoot Cessna technical support an email. See if they still offer "design drawings" for sale. Explain your specific issue but keep it short and concise. However, may want to wait till more people reply to this as my info is a bit dated.
 
Do you think the routing would be the same on a 172B? If so I can get photos of under the panel in the next couple days and post them for you. It may help.

Do you have the original "T" yoke? or the upgrade to "Y" yoke?

Not much guidance from Cessna on the locations of the engine control cables. I've seen an arrangements of Adel clamps and pull straps to hold the cables away from the yokes.
Pull straps = 3/8" wide strip of aluminum .032
 
Join the 172 club and forum and ask them. Lots of resident experts there! :)

Yes, I have been experimenting with straps/clamps etc and have about concluded that it will have to be something like that. I had hoped that someone might have, or be able to make, a photo underneath an existing panel (I know it isn't easy) that would give me some idea of how Cessna did it. I am trying to make it as correct as possible.

Thanks for the offer, but the "B" model has a different firewall and yoke configuration.

Most every one is different and not a lot of the early birds around to take a look at.

Most of the early 172s I see the controls go under the "T" bar, and have a strap from the bottom of the glove box to the cables, holding them away from the vertical section of the yoke.
 
Think of the children!! :eek:

Yes... child mutation (FAA regulated) can happen if you work on your own plane.

You're not a A&P and you're rebuilding a airplane?

You're surprised? I knew people who flew, never even had a student pilot certificate, owned and flew planes w/ out a certificate, PPC who filed IFR and then flew in IMC. This is America, beat the man and the system.
 
Not surprised. Whenever I had a problem with a B-767 maintenance I wish I'd had a forum to consult instead of the AMM or Boeing engineering.

When I was working across AL, MS and GA, I never ceased to be amazed at the number of "pilots" who were "illegal" in some way. There are renegades everywhere but I found them to be far more prevalent down there.
