There are very many wealth people and some even own aircraft of far greater value than an AW139, I suggest that nobody flying around in a private BBJ is attempting to get into (and I’m being silly to make the point) Fenland for example! So it does seem that in some cases this type of person can be controlled.
It's a bit different Pitts, fixed wing OEMs give owners an FCOM, helicopter OEMs traditionally do not leaving the operator to work out an Ops Manual Part B (in my part of the world).
After the ETAP and Sumburgh accidents, the helicopter OEMs have realised their exposure and are scrambling to catch up with the fixed wing manufacturers. It's one of the main synergies Guillaume Faury (the new Airbus Helicopters CEO)is hoping to gain from the closer alignment with the Airbus parent.
