Brief Description: Fuse Final Assembly – Lower Longerons
I clecoed in the lower longerons (F-843) and then installed the 2 screws and 4 bolts per side and torqued everything up snug. AN3-5A = 24 in./lbs. 832 screws = 13 in./lbs.
Next step was to rivet the lower longerons to the floor assembly. Most of the rivets were driven with the pneumatic squeezer and the longeron yoke! But 4 on each side had to be bucked by hand as the LG attach plate is in the way. All good.
