That's doubly a Boeing problem, or maybe triply:
* According to the whistleblower, Spirit personnel/contractors/??? don't have access to the formal system of record that Boeing uses to document manufacturing progress, changes, repairs etc
* So when Boeing gives Spirit some work to do, Boeing is responsible for observing and documenting what was done
* It being Boeing's aircraft being worked on in Boeing's facility, Boeing is also responsible for all aspects of quality and manufacture
It's just a bad system. If you have contractors doing critical work closely integrated with employees' work, you have to give the contractors the maximum allowable trust and credentials, not treat them like interlopers. Otherwise you will get interloper quality results.
