Hi Guys,
I was fabricating a bunch of fuselage components today and stumbled across an interesting one that I haven't been able to find an answer for. I'm hoping it's not because I've missed something obvious (or my math is bad).
The long edge of F-695 is supposedly 7 9/32 in length (or 233/32). There are 14 holes, so 13 spaces at half inch each (208/32). The first rivet from the top should be 5/8 in from the edge, or 20/32. Adding this 20/32 to the 13 spaces (208/32) gives a total of 228/32. Therefore, the bottom most hole is only 5/32 from the edge of the piece (233-228). The minimum edge distance is 8/32 for this example according to AC43.13-1B pg 4-19, so I seem to be too close to the edge by 3/32. From your perspective, should I:
(A) Remove one rivet hole and evenly space the remainder so that an 8/32 edge distance is achieved.
(B) Squeeze the 14 holes closer together so that an 8/32 edge distance is achieved.
(C) Not worry about it.
(D) Do something completely different.
Anyway, I'll hit the mothership up on this too and let you guys know what I hear.
Cheers,
Tom.
