Control Surface Balancing

General

The weight and balance of control surfaces needs to be determined
after execution of work on the surface with (potential) change of total
mass and/or balancing (example: new paint or other repair).

NOTE

Check weighing scale currency of calibration.

Procedures described are of general nature and not limited to a
specific airplane unless stated specifically.

▶

If required: Remove the respective control surfaces from the aircraft.

▶

Determine total weight of the control surface and enter in respective
column of record form.

▶

Use balancing support mandrels as shown in the following figure:

▶

Level the balancing support mandrels (3, Figures 19 thru 22) to a
horizontal attitude.

▶

Install bolts in two control surface ball bearings (flap, rudder,
elevator).

▶

Install a wire in the aileron piano hinge.
