Install temporarily the F-766 assembly in the fuselage. Slide a bolt through the F-766B angle, the flap motor, the washer and the F-766D spacer (Section B-B' Dwg 33). I already positioned the shaft of the flap motor half way between its travel stops. Bolt the motor to the WD-613-EF actuator arm as shown on DWG 33. Calmp the F-766B bracket to the channel and drill it, using the holes in the channel as guides. Cleco the F-760 Flap Actuator covers to the channel and mark the the holes on the F-785 backrest channel. Enlage the hole around the bolt headin the F-760 Flap Actuator Cover.
