"is this so hard to understand"
I think I get your drift.
So you are saying that although there have been repeated incidents within one organization with reference to:
Fatigue
Aircraft Configuration
Flight Deck Discipline
Procedural Compliance
There is no reason for concern, as the events are reported and the organization may treat each event as a learning outcome.
Is the difference one airline can $#>k up, not report & be grounded whereas another airline can $#>k up, report the incident and they are protected?
