The flight instructor was giving flight instruction to a new-hire pilot in preparation for his 14 CFR Part 135 check ride. Another new-hire pilot was seated in the back to observe the training. The pilot trainee was performing a hydraulics-off, run-on landing. As the student approached the touchdown point the instructor reminded him to keep his airspeed up. He reported that just prior to touchdown, the aircraft controls became very stiff. At that point, the flight instructor directed the pilot trainee to re-engage the hydraulics isolation switch on the collective control. The student re-engaged the hydraulics but reported that the controls remained stiff and he was having difficulty applying forward cyclic. As the instructor got on the controls it started a slow turn to the left. As the instructor attempted to counteract the turn rate increased. The helicopter impacted the ground in a left turn with rear lateral movement. The landing gear skids collapsed.
Probable Cause: the instructor pilot's failure to maintain control of the helicopter.
