The Federal Aviation Administration said it would investigate allegations that titanium had entered the supply chain via falsified documents.

Boeing and Airbus, the two biggest commercial airline makers, may have used titanium sold using fake documents, according to evidence from a supplier that has triggered a Federal Aviation Administration investigation.

The FAA said in a statement to NBC News on Friday morning it would look into allegations from Spirit Aerosystems that the two aviation giants used titanium in their planes that came with paperwork verifying its authenticity that could have been falsified.

The news adds to a troubled period for Boeing, which is the subject of ongoing federal investigations for alleged safety problems. But the news also brings its fierce rival, France-headquartered Airbus, into the wider scrutiny the aviation industry is facing.

    Still titanium, but likely sourced differently and not batch tested to verify exact mechanical properties. Only time you’d tell the difference is when it fails prematurely.

      Presumably there must be something physically different about the weaker titanium, like a different structure of all the crystals in it or something? Is there any way to measure that?

        Sometimes only by destructive testing. But either way, the high cost of the parts is the paper trail verifying the testing to a certain standard.

          I’m aware that it can analyze chemical composition (I work in a factory that relates to such devices), but I’m unaware of them being able to detect things like weaknesses in a grain structure, the devices I’m familiar with at least would just tell you if a piece of titanium has other elements contaminating it. Unless there’s more that can be done with them than I’ve had explained to me, which is possible

            I don’t know about crystalline structure, but impurities are probably the most common way that a sample might fail testing. I’m sure that improper annealing or something would also cause problems, but I’m not a metallurgist so I can’t say for sure.
