Hi everyone!
I run into another problem with hole enlargement when drilling out defective rivet. This time it's on the F-804G-1 Vertical Bar at the Center Section, the drill managed to depart on the pre-drilled hole and make its way to make a nice "8" on the other end.
It also damaged the F-804B-1 Center Section Spar web and F-804C bulkhead.
I consider enlarge the hole next size up, but before I do so, I would like to if anyone has a better idea. Another thing is it requires a fairly long rivet (-14), which I need to special order.
Another fix is drilling a new hole between the damaged hole and the AN bolt and leave the damaged hole empty.
The F-804G-1 Vertical Bar has two AN4 bolts and two AN426 rivet holding it in place. Is leaving the damage hole empty an acceptable option?
Many thanks!
Hank
