Brief Description: Fwd Fuselage - Lower Longeron F 717 3
WARNING there is a dimension to change to ensure good edge margins. I saw this on other construction logs and verified it myself. The drawing says the centerline for the holes on the bottom of the lower longeron are to be 1/2 inch from edge. I changed this to 7/16 because I wanted to make sure the holes wouldn't violate edge margin on the steel weld mount.
Remember the corner of the steel weld mount is not welded. It is split. And these holes get drilled to #12 for AN 3 bolts.
