With the flap actuator weldment lightly bolted down, the center bearing block is used to match drill to the floor (actually, a rib under the floor).

When holes are drilled for the center bearing block, AN3 nutplates are installed under the rib and floor, the bearing is lubricated with some white lithium, the top half of the block is installed and the bolts are torqued.  Torquing the end bearing blocks finishes the installation of the weldment.



Next, the flap actuator channel is set in place and the weldment is bolted to the actuator arm and safety wired.

I finished the installation of the flap actuator channel and flap motor, which at this point, was simply a matter of tightening the screws.
