Ref: Building a Pietenpol

http://www.cpc-world.com/photos/Spar.jpg

This spar was built for a Pietenpol Aircamper. I believe it is a Jim Wills modification to the plans for PFA approval in the UK. It is my understanding that all Pietenpols in the UK have this type of spar construction.

Can someone point me to reference material specific to this type of spar construction? Is it better than similar construction of a closed box with ply on both sides?

Thanks CL
