(17-3 steps 7 & 9): A
quick day today… just stuck my head out in the shop &
thought I'd get the splice strips taken care of. These have the
largest holes that we've dimpled so far. The large holes are for
the #8 screws that will attach the fuel tanks to the outboard leading
edges. The plans stress ensuring these holes are 'carefully'
deburred, or else cracking can be an issue. Anyway, I made sure
all the holes in the splice strips were deburred, and then countersunk
the nutplate attachment holes, and then finally dimpled the #8
holes. We had 3 of them show signs of small cracks, so I used one
of our small needle files to file them out. No biggie, but I feel
better about it.
