RV-7 tailwheel tip-up

I'm about to drill a 5/8" hole in the bottom of my tailcone skin to be able
to get a socket around the AN365-428 nut that goes on the bottom of the
tailwheel spring mount (bolt going through the mount & spring), just aft of
the F-711 bulkhead. I couldn't find a single mention of this in the
drawings, but it sure seems like a foregone conclusion that it has to
happen, since the nut isn't going to clear the tailcone skin internally..and
there theoretically may need to be a way to r&r the tailwheel spring at some
future point.

Can somebody just confirm for my sanity that this is status quo?

Thanks in advance,

Dan - Me too! No mention anywhere of a hole, but I came to the same conclusion you did, drilled a hole for maintenance purposes, and went on with everything else. I figured it would be a great way for moisture to drain out as well!

My buddies with LongEZs have some thin tape that can be used to cover the hole if I want to go fast.

Dan,

I came to the same conclusion that if a nut is to be placed on the bolt, the
hole must be enlarged. I have decided to put a blank rubber firewall
grommet like you see on automobile firewalls to plug the hole after I
finish.

I am more concerned about water getting in from the outside than I am about
trapping water inside. Besides, the rubber grommet can be removed from time
to time during preflight to check for trapped moisture.

Dan,

If you turn that bolt around (nut on top) the skin will clear. You do have to install the tailwheel spring before you put the assembly together though and this will make it impossible to remove unless you drill out the little hole. I figure if I ever need to remove the thing I'll drill the hole out then. If you have already installed all of it without the spring bolted to the mount then you will have to drill the little hole out.
