Drilling longeron forward of F-904 (Full size) Clamped the longerons to the skin and checked the forward end. They should be 3/4" short of the skin edge. Each needed to be trimmed about 1/4" to meet that. Then re-clamped after cutting the longeron short with a cut-off wheel. Drilled the holes through the skin and longeron. |
