During my FlightSafety 76 initial course, I was told that the VNE on the 76 is set more from a tail boom fatigue issue rather than retreating blade stall. It was mentioned that flying past VNE, as well as prolonged flight at high power settings, will put undue stress on the tail boom and vertical fin. The first indication of this would be loose screws on the panel behind the left main gear.
Just wondering if this is factual.
Thanks
