ENG Ship down in Seattle
Assuming it was LTE or damage to tail rotor, the AS350 B2 is very difficult to recover from at low height due to the E-gate throttle located between the front seats. Basically you need a third hand for the throttle because it's not the twist grip variety.
If it were hydraulic failure, again it could be a handful at low level and no airspeed. Due to the fuselage rotations before the crash, I'm guessing it wasn't rubber band failure.
My 2 cents.
