KR> Wood Spars

[clarkma1...@wmconnect.com]

Can anyone tell me the life span of wooden spars before they should be 
replaced. My project was started in the early 80 (20 years ago) from the 
fuselage to 
all spars which were checked by an A& P and signed off in the log book, but 
the KR-2 wasn't completed, it's always been kept in a building and well 
protected.  Should I build new spars or continue on with what's been built?
