What that certificate attests is that the airline has appropriate infrastructure in place to operate the specific aircraft type(s) safely. That means appropriately trained and qualified technicians to maintain the aircraft, a proper supply chain to procurement airworthy spare parts, properly trained aircrew, etc. Operating aircraft isn't like web development where you can just push a buggy pile of JavaScript and fix…
It's the distinction between private and commercial that doesn't make sense to me. If I want to fly from A to B, whether I get paid or not doesn't make a difference to the safety of the passengers. If I have a private pilot cert, I am qualified to fly the aircraft safely. Enlighten me if I'm wrong.
The PPL is about 40 - 60 hours of experience at the time of rating, and CPL is 200+ hours. New PPL holders do not have an IFR endorsement, while most CPLs do. So the qualifications are vastly different.
In the industry, we say that a PPL is "a license to learn."
I read both press releases and the missing info is which aircraft were being used with the unrated pilots. If it was a plane requiring a SIC, and the second pilot was a student, then that was the real reason for the revocation.
Also, the catchall "recklessness" can be used at any time. Flying pax without a rated SIC would be an easy complaint to win.
