I needed to remove the left fuel tank to remove old pitot lines which weren't needed in front of the main spar now. They need to be aft of the main spar to go rearward to the Dynon ADAHRS connection. All screws came out except one which stripped, of course.. Tried different techniques, but drilling #40 center and using a #1 size Craftsman EZ out worked. Flipped the wing upside down to work in the pitot area with easier access.
One screw stripped. Drilled center and used EZ out. See whats left when you try other methods?
Removed 2 aluminum pitot lines not needed in front of spar now.
Better access by turning wing over to work on pitot.
