Posting in the general area to get widest distribution/ideas.
I have an email in to Van's as well.
RV8, QB wings.
I was doing the initial metal work of dressing edges, rounding corners and de-burring etc. on the outboard bottom wing skin today when I found a mistake made during the construction on one of my QB wings.
In a nutshell they countersunk for, and installed a plate nut in the wrong place. Look at the furthest left holes in the spar web for the access panel
Here is another picture with the skin still correctly aligned side to side but pulled back slightly to allow a better visual understanding of the problem.
The only thing I can come up with is to remove the incorrectly placed plate nut.
Use hole #1 as is since it is correct
Use the now open hole #2 to attach the skin per its design.
Abandon and/or fill hole #3. Suggestions on rivet size would be appreciated.
Enlarge hole #4 to accept the access plate dimple and screw.
Use hole #5 for the K2000 one lug plate nut.
Drill and countersink a new hole at position #6 for the other hole in the K2000 plate nut.
I am interested to hear what Van's has to say about one more hole in the spar and the proximity of two holes that are countersunk deeply to accept access plate dimples.
Does anybody else have suggestions on other courses of action?
