That could happen if an inexperienced pilot (or non-pilot, perhaps, in this case) was "playing Air Wolf." You can't screw around like that in a helicopter with a two-bladed system.

      donhillberg Pylon whirl, It's not the first or last,Thats why Kert settled. Doubt pilot error in cruise flight.

The long mast in the R-44 dosen't help either.

      scottswanberg Makes sense. I learn something new about these things every day. Thanks!

Was the situation in this accident aircraft consistent with this profile? The forward CG would be easy with two big guys up front and nothing behind them. Oddly, I was flying in these conditions just yesterday and noticed more than the usual amount of vibration in the helicopter. Certainly not worth landing for, but I was thinking of taking my mechanic for a flight if it persists. Now wondering if it had anything to do with this. Thanks again for this link, Scott. Certainly gives me plenty to think about -- and another reason to lose weight!  less

The description of mast rocking says that it does NOT cause the main rotor blades to diverge from their normal path of rotation. This accident (http://www.ntsb.gov/aviationquery/brief.aspx?ev_id=20060510X00540&key=1) was caused by the tailboom getting cut off because the main rotor blades DID diverge from their normal path of rotation. Robinson may have settled simply to avoid a costly lawsuit and questions regarding the safety of their helicopters.  less

Anything from clear air turbulence to a "let's put this new ship through it's paces" moment, but I am reasonably sure that it was not a design flaw that caused this crash. If it WAS a mechanical failure, I think it was probably more of a fluke than anything else. I think Robinson settled because they knew it was the right thing to do, both for their business and for the families of the departed. There are just too many of these ships flying around worldwide for there to be serious design flaws.  less

    does anyone know what the pilot and aircraft requirements are ??
