Objectives of this task:

Materials required:
Card J16 “
Electric Flaps

Fit the flap shaft
Remove the inner flap drive arm from the flap drive shaft by removing the 2 x AN3 bolts and
pulling the flap drive arm completely off of the shaft.
Feed the bare shaft into the cabin through the flap shaft
mount in the top left of the cabin, first taking care that
the bolt holes for the inner flap drive arm will end up
on the right-hand side of the cabin, and slip the inner
flap drive arm over the shaft before the shaft exits the
cabin through the right side flap shaft mount.
Ensure that the flap drive arm will be 180° away from
the outer flap drive arms as shown above in red.
Refit the inner flap drive arm with the AN3 bolts, flat
washers and Nyloc nuts and tighten the nuts to safety.
Fit the outer flap drive arms to each end of the flap
shaft and secure each with an AN3 bolt and Nyloc nut
as shown at right. Tighten the nuts to safety.
Prepare the flap drive motor assembly
Rivet the 3 captive nuts to the mounting bracket as shown below right:
Fit the large rod end and lock nut to the end of
the actuating rod on the electric flap motor and
thread fully into the rod.
Bolt the mounting bracket to the post on the
gear case of the flap motor assembly by
placing a Bundy tube through the post and then
bolting through the bracket and the post.
