Yes I read that lastnight and it is pretty tragic. I've been looking into going for a microlight but this has really made me think. I suppose anywhere in aviation you can get incomplete history, unrecorded maintenance etc which was just part of the problem with this A/C but not correctly embodying a Service Bulletin is inexcusable and you'd think the inspectors should know about the construction of the A/C and differing rivets.
I would say the Air Exp flights are a safe in these as any other mode of flight although all these Air Exp flights are questionable really (commercial flight?)
