Now a report a couple of hours ago saying the information conveyed by the pilot was that he was having difficulty controlling RPM, and that he had initiated an autorotation that was short of the runway, which ended up as it did.
I take it that means he was having difficulty with RMP surging, or keeping the rotor in the green. Yet he could hover.
Possible developing seizure of the main transmission. My training was that if the transmission was seizing, not to roll the power off for the auto. If you do, the blades stop.
