In my opinion REDL was an avoidable maintenance error so I disregard that one. One failure is of course not statistically significant so whether it was 400k hrs or 4 million doesn’t tell us much! What we do know is pilots cause accidents much more frequently. Fortunately the brave new world sees helicopters flying without pilots, so that one can be ticked off the list!
