I have been thinking about changing out some of the AN bolts for drilled head bolts. Such as AN3H-4A for AN3-4A. This would allow the use of safety wire. I'm not suggesting replacing all of the bolts, but just one example would be the bolts that attach WD-1207 and WD-1208 to the stabalator spar. It looks like it would be difficult to inspect these bolts with the aircraft assembled. I know we are using locking nut plates, but the safety wire would be visable and easy to inspect. Is this too much like belt and suspenders? What do you guys think? If you say "built it like the plans" because it is an ELSA, I would be willing to ask Van for a letter of authorization to substitute the drilled heads.
