Just saw it. New ENG 206 up in Rhode Island. Thankfully no serious
injuries.

Interesting. Looks maybe like LTE. It made a noticable yaw to the
right on short final.

It looks like it may have been a failure of the tail rotor drive
or controls. The tail rotor itself appears to be intact.

It sounded like engine failure to me, however if that was it, the
pilot should have been able to manage it better than that. Does that
heli have hydraulic controls? What happens to the hydraulic controls
if the engine fails? On a car, you still have steering, however, its
a lot harder to work whe the engine quits turning the hydraulic pump.
Is it the same way on a heli? If it is, then maybe the loss of
control was the pilot trying to force the controls.

The 206 has hydraulic controls. The pump is driven by the transmission, so
if the rotor is turning then the controls are powered. If the hydraulics
fail, the aircraft is still flyable with a little difficulty; the pilot will
have increased control loads.

Also, early versions controlled the tail pitch hydraulically, most have all
mechanical tail rotor pitch control.

In an engine failure woudnt the Jet Ranger yaw to the left? It looked
like a pretty abrupt uncommanded right yaw to me.

We'll probably have to wait for the ntsb report to be sure. I'm not
sure how long that takes, but I know one locally that happened in Feb
that is still waiting. (Last I checked.)

The pilot made an excessively hot approach, and when he pulled pitch at the
bottom, consumed so much power that the engine simply had an insufficient
amount left to deliver to the tail rotor. The majority of incidents
characterized as "loss of tailrotor effectiveness" actually occur under
similar circumstances to this. It's really just a failure to maintain
coordinated flight. The problem with the 206 in this context is not a lack
of tailrotor thrust, but a lack of surplus power at high gross weights or
high DAs.

Pretty much seemed like classic LTE to me, "highish" power setting,
low forward airspeed and pilot may have been concentrating on the
target of the camera shoot. It would be interesting to know the angle
of the wind.

They were fortunate to be so low, a similar incident in Melbourne
Australia several years ago (Bell 206 filming) happened from just
under 1000' and the injuries were severe - there's video footage of
that somewhere, filmed from ON BOARD the helicopter: very scary stuff!

And, of course, some prime examples in my book "Fatal Traps For
Helicopter Pilots" (see http://www.fataltraps.com ) - I'd be silly not
to mention that of course!

Compliments of the Festive Season everyone,
