On the subject of failures in general, am I the only one who thinks there have just been way too many of these in the last couple years?  In virtually every case, the engine has been the victim, rather than the cause of the problem, but to the casual observer, it looks bad for the rotary.  I'd hate to calculate the number of flight hours per serious problem for currently flying rotaries.  I'd also hate for the insurance companies to do it.  Let's hope this trend doesn't continue.  

 

Cheers,

Rusty (one rotor, no prop)
