Brief Description: FUS36 drill-out and FUS30 fitting
With the fin attach fitting out of the way, I was able to proceed with drilling out FUS36 bottom into FUS29 and FUS 30. With the top FUS29 only clecoed, I had easy access to all this (Manual says to climb inot fuselage to do this....crazy!). Image 2 and 3 show progressive drilling of various internal structures.
