This means manufacturers can't just wash their hands of responsibility if their product, sold without any need for you to check for faults, ends up being defective.nnThis covers all sorts of defects - whether in design, manufacturing, or lack of proper warnings. But, there's a catch. If you're an expert user - like a professional pilot using an airplane - different rules might apply.
