OMR, since the incentive bonuses of most upper level managers, both helicopter and oil companies, are based on quarterly performance, there is little reason for them to care about long-term costs. With the profit levels being posted, lawsuits are only minor annoyances, and there is little evidence that the managers care about the safety of employees other than from an economic standpoint.
Perhaps I'm too cynical, but I've been observing the actions of these companies at close range for well over 20 years, and that has been my consistent impression.
