Nev, the aircraft was airworthy at the time of the incident, it was only a couple of months ago. The motor was zero hour rebuilt shortly before that, but due to the prop strike will have to be stripped down.
Yes, it has a one piece spar. The fabric is the least of his worries. Weight just fits into RAA registration and changing from GA was part of the plan.
The reason for posting is to try to find a wing, spar, or even an old aircraft in order to reduce the amount of work involved.
