(a)
Push up with a force of approximately 21 pounds (the spoiler panel weight of 16 pounds plus 5 pounds pull force) on the spoiler trailing edge directly opposite the power control actuator and within 0.5 inch of the trailing edge of the spoiler panel.
(b)
Measure the play on the inboard edge of the spoiler not more than 1/2 inch from the trailing edge.
(c)
Make sure the spoiler play is not more than 0.10 inch.

Do a check of the play of the spoilers No. 4 and 5 (aluminum/fiberglass):
(a)
Push up with a force of approximately 33 pounds (the spoiler panel weight of 28 pounds plus 5 pounds pull force) at the midpoint between the two power control actuators of the spoiler, and within 0.5 inch of the panel trailing edge of the spoiler.
(b)
Measure the play on the inboard edge of the spoiler not more than 1/2 inch from the trailing edge.
(c)
Make sure the spoiler play is not more than 0.20 inch.

Use the Aileron Tab Alignment Protractor to Identify the Aileron Tab Neutral Position
S 482-024
(1)
Use the protractor to identify the aileron tab neutral position:
(a)
Make sure that the aileron aligns with the index mark on the wing (use a tolerance of +/- 0.03 inch).
(b)
Hold the protractor on the bottom side of the aileron, 0.5 inch away from the inboard end of the aileron tab (Fig. 201).
(c)
Move the protractor forward until the scale lightly touches the tab trailing edge.
(d)
Read the scale on the protractor to find the position of the aileron tab.
(e)
Do steps (a) thru (d) again at the middle point of the aileron tab, and 0.5 inches away from the outboard end of the aileron tab.
