Don't have a problem with any of what you say especially:
Please, to be precise and to teach proper procedure for recovery, do not call overpitching and loss of yaw control LTE, call it overpitching."
What concerns me is: "Are allowing the regulator and investigator to just blame the "tanks" for the fatality."
We must question how the R44 got into this predicament. Was the 44 in the wrong part of the power curve and the rest is just the unfortunate result.
