Rear Wing Spar

Resumed assembly work on the rear wing spar. Parts W15-06L and W15-06R should be completely symmetrical (rear wing spar attach fittings), but both don’t seem to precisely match the plans, the right side deviating more than the left. Looks like cut badly then filed. Worked with Ross to take a test measure of what the angle of the fittings would be on each side, and it was approaching 2 degrees. That could make for a nasty stall break! Scrapped these parts and ordered replacements from Sonex.
