I'm installing microphone and headphone jacks in my RV-7A -- both jacks come with built in locking tabs.  I understand how to isolate the jack itself from the aluminum structure using uninsulated shoulder washers, but how to isolate the locking tab from the structure?  Any ideas?  Cut off the locking tabs?



Also, I'm planning on installing both jacks vertically on the aft part of the arm rest (behind seatback) -- seems to be out of the way, it's not near any other wiring and keeps the headset wires out of the way when plugged into the jacks -- was going to run the leads forward up under the canopy rail where the static line lives.  Anybody have any opinion (pro or con) on this location?





Thanks for the help.  Do not archive.

Hi Lincoln,Â 



I found the best way to choose the location was sit in the part-built Jodel with headset and try out a few places. Â It's surprising how many places interfere with your elbow during cruise, or your knee when landing, or your kneeboard, etc...

 



FWIW.

Lincoln;  

   

I presume you meant to say “insulated” not “un-insulated” shoulder washers?   

Secondly I’m not familiar with any microphone or headphone jacks having “locking tabs”. Can you attach a photograph or link showing this feature so that we can understand exactly what it is you’re referring to and come up with a solution for you? If it’s similar to the lock tab provided on switch anti-rotation washers, then drilling a clearance hole near the edge of your shoulder washer to match its location might work provided the shoulder washer is thick enough. If not, then an additional plain fibre washer added to the shouldered washer might do the trick.   

A vertical mounting of jacks behind the seatback can be quite effective in preventing cable tangles and interference with piloting duties. It often makes for a much cleaner, uncluttered cockpit environment. When the aircraft design permits, the ceiling behind the seats is another good choice for the jacks.   

The cable routing you propose should be acceptable.

The underarm, behind seat position for the jacks in the arm rest is good. I  have mine mounted there and seems well out of the way with space beside the seat  cushions to store the headsets.
