Aileron Balance Configuration - Piper Dakota Maintenance Manual

Balance control surface as follows:
1. Ensure that control surface is in its final flight configuration with static wicks, trim tabs, trim tab push
pull rod, and control surface tip (as applicable) installed. The surface should be painted and trim/servo
tabs placed in neutral position.
Because paint is a considerable balance factor, it is recommended
that existing paint be removed prior to repainting a control
surface.
2. Place hinge bolts through control surfaces and place control surface on a holding fixture.
3. Avoiding rivets, place balancing tool on control surface with tool's hinge centerline directly over hinge
line of control surface.
4. Adjust movable trailing edge support to fit width of control surface. Tighten set screw on trailing edge
support.
5. Adjust trailing edge support vertically until beam is parallel with control surface chord line.
6. Remove tool from control surface and balance tool itself by adding or removing nuts or washers from
the beam balancing bolt. When balancing the tool, the movable weight must be at bar's hinge
centerline.
7. After balancing the tool, reattach it to control surface. Keep beam positioned 90° from control surface
hinge line.
8. Determine balance of control surface by sliding movable weight along balance beam.
9. Read scale when bubble in level is centered. Since the movable weight weighs three pounds, every
inch it is moved from center of beam equals three inch-pounds of force.
