It would appear that the distance from hole to edge must be a good 1.5 times the diameter of the bolt - which is a standard if I remember correctly. This comes to 7.14 mm for AN3. The manual requires 7.62 mm. Jan de Jong On 1/20/2013 3:58 AM, Kyle P wrote: > > After the wings were painted the holes on w19/w20 don't allign with > w18.

That is what I am assuming the problem is. Normally I profess for my clients to use a 2 D edge distance. (Ref TO 1-1A or similar) That is 3/8" 10mm from the edge of the hole and is a standard, however if you look at Chapter 9 of the Mono manual You can see that the wing skin to hole center was supposed to be about 13 mm or 1/2 inch. (The fore and aft edge distance was supposed to be 13 mm also.) That means from the edge of the hole to the wing skin is supposed to be 3/32 less 1/2 or 13/32 or with glue etc. ended up at about 3/8 inch. When my painter finishes I grind the paint and filler away to get my flap hinges to fit rather than compromise my edge distance. It takes 5 minutes to touch up the paint. I know you would prefer to grind and go to final assembly, however, I would rather you not grind off your flap bracket. Also note that grinding on the aluminum tends to cause micro fractures and when you eventually hit your flap you may end up with a small crack that the bolt and washers tend to cover up until you notice the flap bracket is loose. Use a good smooth file for proper smoothing afterwards. It seems the upholsterers tend to lean on the flaps during their work, or the mono snags a landing light, tie down tire or something so flap damage must be anticipated, therefore a little extra meat is best in the flap brackets. A painter just fills and paints and doesn't necessarily care about their attention to fit and finish once the plane is taken apart, they figure it's your job to put it together. The painter (or we amateurs)also fill aileron gaps, door sill and hinge gaps, static pressure ports on your pitot tube, and your AOA, as you found out. I never contract a painter without his agreeing to touch up after the 40 hours for just this reason, even if the plane was trial assembled for clearances after priming and before final paint. If the AOA was not installed with an access panel or drain / moisture tap on the underside (Looks like a fuel drain in the wing bottom) that allows cleaning and draining of the upper port water out of the bottom or for future maintenance. If not, you need to look for a pin hole. Tap around the area you placed the fitting and you'll find the area. Hopefully it has a small pin hole in your paint finish. If you can reach your static fitting, from a tip light hole or such with a probe or long needle nose, then disconnect the tube and use your long angle drill and a #60 bit to poke through the fitting. If no access is possible, then you can find general area by tapping or use your measurements from the build. Assuming AOA install was made without regard to maintenance, make a small hole (1 inch or so) to gain access from below. Cover the hole with a small plumbing or furniture cap. I suggest a stick on decal to mark where the hole is for washing and waxing later on. The work now is worth it in the long run.

I couldn't find a value for how much material I can remove from the brackets and still be in "limits." I like to avoid sanding down into the paint to make room for the brackets. Also on a side note, the top port for the AOA was filled and painted over. Any tricks to clearing out the hole?
