Email to Vans "We drilled a hole for the vent line fitting on the left hand side of the fuselage in a location that is incorrect. As you can see from the photo attached, the hole is too low and is too close to the edge of the wing fairing. If we drill a hole in the correct place there will only be 3/32" distance between the holes. Should we drill a hole a little higher than the correct location? What should we do about the hole that is located incorrectly? Any other ideas on how we can fix this? Do the two spacers on the vent fitting both go on the inside of the fuse skin or is it one on each side of the skin? We think it is the former, but just want to check." From Vans "You can drill the vent line a little higher if it does not interfere with anything. Do nothing with the misplaced hole. The washers just make the material thicker to account for the shoulder on the bulkhead fitting. It doesn't make any difference where they are placed."
