Sorry it Shell Aircraft, not the helicopter industry, that invented HUMS and every other major helicopter safety improvement. As Shell Aircraft says:
Analysis shows that the helicopter industry has not fully embraced the improvements in design, equipment, operating procedures, training and maintenance practices that enabled the airlines to achieve their safety improvements.
Also:
it is very unlikely that the International Helicopter Safety Symposium's goal can be achieved without the mitigation offered by all the projected further improvements, including introduction of new types. "Business as usual" is therefore not an acceptable option. The only option that will enable the long-term goal to be met would be to acquire new helicopters built to the latest design standard.
