> This is standard in aviation (which is why structural failure airplane crashes of production aircraft are very rare) but something Space-X wasn't doing. That is going to require sources. Primary responsibility for quality is going to have been the original manufacturer's. SpaceX of course will have had to (and I don't believe didn't) done their own check testing of components, but you write a contract with a supplier to put the risk on them for the timely supply of to-spec and to-tolerance parts. And then you take it to your supplier when they've failed to meet their contracted failure rates, which could also be called "tightening up your supply chain." I'm sure there'll be more quality involvement on SpaceX's side but I'd be awfully surprised if they weren't generally following industry standards. Failures of novel engineering happens sometimes.
