AILERONS
Aileron frames are all metal, single spar, fabric covered, attached to the supporting brackets with clevis
type fittings. The leading edge of the aileron is designed to provide additional ease of control movement.
Fabric is attached to the aileron by the same method used on the wing.

Aileron travel limitations are: 28.5° plus 0° minus 2° up – 18° plus 0° minus 2° down.

FLEXIBILITY OF AILERON HINGE BRACKETS
Aileron floating action is perfectly normal and allowances have been incorporated in the design of the
wing to compensate for it. Due to the length of the hinge bracket and the narrow base attachment on the
spar, it is possible to move the hinge point up or down and the movement is absorbed in the rear spar itself.
A flexible action is desirable at this point to lessen stress. The brackets are bolted and safetied to the spar
and inspected. Unless there is a decided looseness in the movement of the bracket, there is no cause to open
the wing for further inspection.

NOTICE

Spars built at the factory may be solid or spliced and may be laminated vertically or horizontally or both.
They may be of spruce or fir. Spars are manufactured in accordance with drawings approved by the
C.A.A. and may not conform to Manual 18 repair requirements. However this does not waive compliance
with Civil Aeronautics Manual 18 when making spar repairs.
