Good to see that pilot and occupant got out allright.
I hope that the engine failure is not related to a malfunction/breakage of the pipe that is connected between the Gas compressor and the fuel regulator because if it is this wasn't the first one that happened to this particular engine.
The beep-beep-beep sound comes from the engine out anunciator. This model hasn't got a low rotor warning light see aircraft spec's earlier message.
Will be following this tread and accident outcome with interest.
Fly safe
