Gullibell - if you fly your helicopter outside its certification limits or RFM and you get LTE, you can blame the pilot - if you fly it within the RFM and certification and get LTE, you can blame the aircraft.
Didn't airbus (or whatever they were called back then) blame the loss of some gazelles (operated within the RFM and certification) on pilot error, ie poor technique. Insufficient pedal, too late and so on and so forth?
You can't always blame the aircraft, even within its limits.
It is fair to say that perhaps some aircraft are more crashable than others, but when there is a warning on the tin should you blame the designers? (Robinson's being the exception to the rule)
