You would also need to put accidents into the context of hours flown.
I think you may find there will be fewer accidents of the other types that use the words "unexpected loss of power" or "unexplained breakup".
You have to give Robinsons their due, they have made helo flying accessible and affordable for many that would otherwise have little alternative but they have been used in ways Frank never intended.
While not relevant to this accident, the sheer number of fatal accidents that happen in seemingly mundane conditions with little explanation other than simply blaming pilot error still raises concerns.
