That Jet Ranger crash was one of two things.
Most likely it was an engine failure with a loss of Rotor RPM

However seeing how fast the thing descended would also suggest a thing called "Settling with power" This phenomenon occurs with an aircraft at zero to near zero airspeed, in an out of ground effect hover, and with 20 to 100% engine power applied. Under these conditions sometimes the rotor can begin ingesting it's own rotor wash which whips around in big swirling vortexes. Where as air would normally enter the rotor system at nearly no downward speed, when the rotor starts to ingest it's own rotorwash, those down wash velocities from the swirling air can reach 100 MPH. So the aerodynamic angle of attack is obliterated and the helicopter enters into a column of rapidly air that spits the thing out at the bottom at a high rate of descent, destroying the aircraft.

I've seen a crash or two, and been in a few.
Definitely difficult to stay alive when all that stuff has sudden stopage

Called Allouette 2's, they can really do crazy stunts like this:
