I'm looking at the firewall eyeball fittings for a bunch of the cables going through the firewall.



Is there a consensus as to whether the eyeball locking ring should be on the cockpit side or the engine side?  If it is on the engine side and it comes apart, the eyeball halves could fall out and out the bottom of the cowl...in flight they would be gone forever......  If it is on the cockpit side and it comes apart, the eyeball halves will be floating around the cockpit.

I mounted all mine (3 airplanes worth) from the engine side. Access and

convenience dictate the orientation. I'm don't even want to think about

going panel diving with those itty bitty screws. I'm not that masochistic.

They all have lock washers so the chance of any coming loose is practically

nil. If things start shaking that much those aren't the balls I'd worry

about losing. Add some Locktite if you like the belt and suspenders

approach.

If you're looking at the one I'm thinking of, there are two retaining rings.  One is fastened to the firewall with two screws and the other fastens to the first one with four screws through the firewall.  The first one I installed permanently inside the firewall with 'permanent' locktite on its two screws.  Then I installed the eyeball halves with hi-temp RTV to help hold the halves together and seal the joint.  Finally, I installed the last ring with RTV and the remaining four screws.  Even if I lose the screws I doubt I will lose the ring or eyeball halves.  I'd have to lose four screws for that, and all six screws to lose the inner retainer.  Hopefully I'd catch it in inspection before that could happen.  Anyway, as mentioned by Greg, screws to the engine compartment is more accessible, which dictated how I oriented mine.

I'm actually talking about the 'other' type of eyeball fitting - with the blue anodized main fitting, attaching ring, and ball-retainer.  No screws involved - but if the ball retainer comes loose, the ball halves may fall out.



I agree that the 'screw-together' type are probably not prone to this issue.
