I would and do happily fly helicopters with abrasion on the blades - paint worn by dust particles - no big deal - it's not an issue to a well built helicopter - I just won't fly a Robinson! Why? I prefer to live. All helicopters types have histories of fatal accidents. I prefer to fly the types that are well built and clock up fatals mostly as a result of pilot error. One day I might come a cropper and it will be my fault. Why fly a type that can just fall apart in a gentle cruise without pilot provocation? Too much like Russian roulette to me.
