The instructor pilot-command (PIC) of the twin-engine helicopter was giving a newly hired pilot a check out and instruction. After completion of a practice 'hydraulic system off' landing, the PIC performed a normal takeoff (with hydraulics 'ON'). During the takeoff, the helicopter rolled over to the left, and the main rotor blades impacted the ground. The PIC reported that it felt like a 'hydraulic hardover.' Examination of the hydraulic system after the accident did not reveal any defects or anomalies that would validate a hydraulic hardover.
Probable Cause: the rollover during take off for undetermined reasons.
