Answer from Van’s
Posted in Spars & SkeletonReceived a reply from Vans:
These small holes won’t make any significant difference to strength, so just clean them up and move on.
Both holes can be used for pitot/wire etc, but only one needs to be enlarged. The other is already full size.
So I’ll deburr those extra holes as normal, and forget about them.
