Long before it “runs out of HP” (RRPM droop), the MAP limit has been ignored, and the drive train has been abused.
Obvious statement. No aircraft will take itself outside of it's performance envelope.
When there is less headroom or margin for error then the possibility of an exceedance increases, more so when at altitude and warmer temps, especially if you didn't plan properly.
Many a robinson has lost its battle with gravity for this reason, all played out with that single note shriek from the panel.
Unfortunately the limit isn't always understood or respected, so perhaps making it more difficult for someone to be foolish isn't a bad idea.
Not that it is relevant to this accident.
