Cut and Fit the F-717 Longerons - 3 hours

I need to cut the F-717 longerons. I cut the angle just a tad bit longer than the plans indicated.

I started to scallop the angle around the engine mount brackets in effort to maximize edge distances. I managed to get the scallops and fit really tight, but I am contemplating backing these off at some point just to alleviate some pressure points along the welds. just by the continued fitting of the angle, marks are beginning to show on the highpoints of the welds.


I noticed as well that the longerons interfere with the F-713 longerons. I too will have to trim the corners of the F-717 just like everyone else does in the build logs.
