Default Mounting tabs on close tolerance bolts

As suggested above for using spar doubler thru bolts, just replace existing washers with bent plates or tabs to accommodate the extinguisher. No change to existing structure to debate.

The RV6 doesn't have that cover or any of those brackets.

Default Floor attach?

What about attaching the extinguisher to the floor, beside the spar/seat edge?

Default Pilot armrest

I have my small extinguisher mounted on the armrest. With a towel on it; kinda comfy and easier to reach than on the front of the spar.

Default PAX Seat Back Brace (F-638)

My Halon extinguisher bracket is mount on the passenger seat back brace (F-638) and is very easy to reach with or without a PAX. I did use some velcro to help hold it in place but it is very easy to pull away if it is ever needed.

Note: This was not my idea. I first saw it in Bill Flaherty's RV-6 twenty (20) some years ago. I thought it was a great idea and used it without permission.

Actually guys, the vertical shear load is taken out very near to the side of the fuselage by the attachment bolts closest to the side, which go into the parts that make up the bulkhead; F-604, F-804, etc.

Once inboard of that point, there is NO shear in the spar, it is pure bending moment -- constant bending moment. (shear is the gradient of the bending moment).

So as much as we all are reluctant to cut holes 'willy-nilly' in the shear web in the center section area, it really is not doing much but keeping everything where it is supposed to be.
