Snap bushing question

[Randy Walls]

Is it OK to run a SafeAir Dynan pitot line and the wires for the pitot heat through the same snap bushing (assuming the bushing is big enough)? I am trying not to make my ribs look like swiss cheese by drilling extra holes.

Randy,

I don't see why not. The major problem, as I understand it, of multiple wires through the same bushing is potential electrical interference, such as static on your radio coming from something like a strobe wire. Pitot heat should not be high-frequency and in any event shouldn't interfere with the air pressure in your pitot line.

I'm sure if I am wrong on this someone will say so....
