## Probable cause

the manufacturer's pilot's failure to maintain yaw control and main rotor speed while recovering from an unusual attitude induced by the customer pilot's inadequate control inputs while maneuvering at low altitude.  The manufacturer's pilot's inadequate supervision of the flight is also causal.  A factor in the accident was the customer pilot's lack a familiarity with the NOTAR yaw control system.
