Searching around I'm coming up empty with the rules on lightening hole spacing, sizing, flange requirements etc.
Been through the ACs, my A&P books and various aircraft mfg searches on the net. Zippy. Best I get is "..size of lightening hole and width of the flange...are determined by design specifications." No duh.
Obviously, I'm missing it. Anyone point me to the right publication or in the right direction?
Thanks
