Purpose
The ailerons control the airplane around the longitudinal axis.
Location
The ailerons are on the outboard and trailing edge of each
wing.
Physical Description
The aileron assembly contains these components:
* Wing quadrant
* Cable tension spring
* Aileron
* Balance panel (4)
* Balance weights
* Aileron tab control rods
* Aileron balance tab
* Pushrod that connects the quadrant to aileron.
Each wing cable connects the body quadrant with the aileron
wing quadrant. A cable tension spring is at the end of the cable
run. The aileron front spar connects to the wing structure by six
hinges. The forward side of the aileron connects to the balance
panels. The balance weights attach to the lower surface of the
balance panels. The tab connects to the aileron rear spar by
five hinge fittings.
Functional Description
When a wing cable moves, it moves the related wing quadrant
and aileron. The aileron tab rod gets input from aileron
movement and moves the tab in a direction opposite to
aileron movement.
The aileron and the tab on the other wing move an equivalent
amount but in the opposite direction

When the control wheel is centered, the ailerons are
downrigged two degrees. The range of travel is limited by the
aileron PCU stroke. The ailerons can move 19 degrees up and
16 degrees down.

Purpose
The aileron balance panels and tab decrease the force
necessary to move the aileron in flight.
Location
The balance panels are in the number one through four aileron
bays.
Physical Description
The forward edge of the balance panel attaches to the wing
structure through an idler hinge. The aft edge attaches to the
aileron.
Seals connect the hinge assemblies along the two sides of the
balance panel. This makes two separate chambers. The upper
chamber vents to the airstream over the wing and the lower to
the airstream under the wing.
Functional Description
When there is no lateral input, pressure forces occur across the
balance panel and keep the aileron in the neutral position.
When the aileron moves, it causes a differential pressure. This
