My guess on why Globespan has lost its ETOPS approval would be nothing to do with aircrew, however experienced or not.
It looks to me that Globespan's engineering QA department has screwed up big time and have been using a engineering company to turn around the aircraft without the required CAA type approvals.
This is only a guess but as both the CAA and the FAA are involved it leans towards my theory.
However feel free to shot me down.
