I understand you do a lot of low level often rough air flying. Referring to those two 210s,which suffered spar cap failures at similar airframe hours could you give an estimate of the percentage of each aircrafts TT spent in rough air. I realize you probably didn't operate them from new but a rough estimate might be educational for other C210 owners. I know some of the Northern Territory mail planes have around 30,000 hours and I haven't heard of spar cap problems. They have rough air but would mostly fly above it. It's just the short sector routes that would be all rough.
