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 CAA and may or may not conform to
Manual 18 repair requirements. However this does not waive compliance with Civil
Aeronautics Manual #18 when making spar repairs.
