❏
Check the alignment of the flap pushrod with the flap hinge. You will have to file on the
inside of the fork end of P/N 713A and on P/N 743 for clearance when the flaps are all the
way down. At this time, you are primarily concerned about the alignment of the pushrod
between the support hinges (P/N 742). Be sure to check to make sure that the flap torque
tube is correctly positioned so that the actuator will be 40mm to the left side of the aircraft
centerline.
❏
When you are sure that the flap torque tube is properly positioned, final fit the wedge-
shaped blocks for the flap torque tube supports. Glue these blocks to Sta. 2 wing rib.
❏
Do a final check of the position of the flap torque tube. Clamp the outboard torque tube
supports (P/N 765) in place. Remove the rib and drill the four 3/16ӯ holes on a drill
press. If you wish, you may start drilling the holes with all parts clamped in the wing to
assure that you have the supports in the proper position, but we suggest the use of a drill
press to assure parallel holes.
❏
Clamp the rib back in place and install all of the supports for the flap torque tube. Do one
final check of the location of the flap torque tube and pushrod.
Figure 17
❏
Glue Sta. 2, 2-1/2 and 3 wing ribs to the main wing spar. While clamping, check to make
sure that the flap torque tube swings easily on the supports. See Figure 17.
❏
Glue the aft wing spar to the wing ribs and to fuselage frame No. 6.
❏
Clamp the trailing edge rib for wing Sta. 1 to the aft wing spar. This rib is installed so that
it is glued to the outboard end of fuselage frame No. 6 and to the aft face of the aft wing
spar. Check the alignment with the trailing edge string.
❏
Clamp the trailing edge rib for wing Sta. 14 to the aft wing spar. Check the alignment
with the trailing edge string.
