Hi

I'm new to this site and a member of the LAA (EAA equivalent) here in the UK.
I am looking at a rebuild project of a Pitts S1. The set of wings I am looking at are S1-D, (flat bottom section with 4 ailerons) they have built up ribs and the compression ribs have square sections either side.
The help I need is to obtain a set of plans for the wings so I can make sure they 'conform' and obtain the relevant approvals, I have drawings for the S1-S which helps with the fuselage etc but not wings.

If anyone can help with plans/information I would be most grateful.

Best regards

Stuart
