In don't have the info any more, but based on a search on VAF I used two RV-10 wing access panel kits (including pre-punched doubler) forward of the windshield.

I wasn't brave enough to try it, but I saw a Piper Tomahawk year ago that had a removable NACA duct on the side of the fuselage at about where the 6/7/9 have theirs. The rectangular opening (3x6?) resulted in a nice behind the panel and rudder pedal access.

Not only would those access panels be an ugly eyesore prone to water/air leaks, think RESALE value when you get to the point of selling your plane. That would be enough for me to walk away. I like Bobs idea of having the full skin removable with screws a whole lot better. Careful planning of module locations and mounting systems with servicing access in mind would alleviate the need for access panels.

I fully understand that, I have access panels on my plane. If I was building today I would just mount everything so that it could be accessed on the sub panel, it could be accessed via removing the instrument panel. I just could not do that when I had analog gauges. The big brain box for my AFS engine monitor and my Lightspeed Ignition box are mounted under the LH panel. My altitude encoder use to be under the RH panel, no longer needed, now that I'm using the Garmin G3X. I use clear RTV when installing them and they do not leak. I have been back into them a number of times. I made this mod myself, they are not the ones being sold, but are made like them, only smaller. Feel free to go to my web site and look at my ugly plane ;-)

I have four panels like shown in the picture above. I absolutely love them. Been in there multiple times. Looks great and have never had a problem. Actually seems stronger than just skin. The nutplate ring stiffens that area up nicely.

I used 6 of the 10 access panels.
4 in the middle and 2 on the sides.
No problems, and would do again.

Walt is on to something here, I believe.

VAF moderator Sid Mayeaux (Scroll) put access panels in his -7A tip-up and it was not a simple ?cut holes, put in nut-plates, screw panels on? type of deal.

There was more to it than that, by a long shot.

I talked to Sid about it at length and there was some significant work put in so the aircraft was still structurally sound...a call by him to Van?s laid out what their thoughts were regarding a proper bill-of-work to safely accomplish this.

Hopefully, Sid will chime in with more info...
