Deburred both skins E-01406 and E-01407. Deburred E-01405 trim tab spar. Clecoed trim tab as per drawings. Found that one hole on E-01406 skin is misspunched. Emailed Vans with advise. Update: 1 month later after calling Vans and asking for a reply they told me that they lost email and I need to send it to them again. After resending email they said to drill onother hole 2 radiuses away from this one and continue with the build.
