(10) Make sure that both flaps hit the up stops at the same time. If necessary, adjust the rod between the bellcrank in the wing and the flap. Refer to Section 27-00.
WARNING: DO NOT TOUCH THE ACTUATOR WHEN YOU OPERATE IT. THE MOVING PARTS CAN CAUSE INJURY.
(11) Set the actuator to the T/O position: S Hold the actuator clear of the structure. S Set the ALT/BAT switch (Lycoming version) or ELECTRIC MASTER key switch (TAE version) to ON. S Set the FLAP switch to T/O. S When the actuator stops moving, set the flap switch to UP. S When the actuator stops moving, set the ALT/BAT switch (Lycoming version) or ELECTRIC MASTER key switch (TAE version) to OFF. Use a piece of string through the eye end.
(12) Measure the extension of the actuator push-rod. The distance between the center of the eye-end of the actuator rod and the center of the actuator swivel block mounting must be 379.7 mm (14.87 in.).
(13) If the actuator push-rod extension is not correct, adjust the cam rod: S Loosen the nuts which attach the cam rod to the plate at the eye end. S Turn the nuts to move the cam rod. S Tighten the nuts. Refer to Figure 3. One turn clockwise decreases the extension by 1 mm (0.04 in.). Torque: 6.4 Nm (4.7 ft.lb.).
(14) Do items 12 & 13 as necessary to get the correct extension.

Torque: 6.4 Nm (4.7 ft.lb).
(16) Do a test for the correct pre-load in the flap UP position: S Put a loop of adhesive tape on the trailing edge of the left flap opposite the up-stop. S Pull down on the loop of tape with the spring balance until the flap just moves from the up-stop. S Record the value in the Control Surfaces Adjustment Report. The value must be as shown in the Control Surfaces Adjustment Report.
(17) If the pre-load is not correct, adjust the control rod between the bellcrank in the wing and the flap horn. Do items 16 & 17 again as necessary. Refer to Section 27-00.
(18) Do items 16 & 17 for the right flap.
(19) Do a test of the flap system. Refer to Paragraph 3.
(20) Do an inspection of all the controls that you have adjusted. S If necessary for your airworthiness authority, do a second inspection of the controls.
