Forward-looking installation of wire conduit for future additions

[Rick Junkin]

If you’re going to have the interior panels out of your airplane, do yourself a favor and run an aircraft-grade length of 1” ID plastic tubing from the instrument panel to the aft instrument bay. If you need to do any wire runs in the future you’ll be able to use the tubing as a conduit and not need to do any interior removal.

The back story is I had my electric standby vacuum system removed and Scotty at Precision Avionics Specialists in Griffin GA suggested we leave the vacuum line from the standby pump in the rear avionics bay to the instrument panel in place in case I need to add any wiring front to back in the future. If I need it I will save some labor hours, if I don’t it only costs a few onces to leave it in place. Genius.

I’m sure this has been recommended elsewhere but I wanted to share. I’m always learning something.

Cheers,
Rick

Likewise, something reasonably smart that was done on my airplane during the last avionics upgrade was placing a bundle of CANbus cables from under the panel to the avionics shelf in the tail.   My GMU11 and GAD29B are both back there, so I guess they just took the opportunity to bundle a bunch of cables rather than just what they needed.   Might be handy in the future.
