## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

AS STATED BY PILOTS, WHILE PERFORMING NVG HYDRAULIC OFF MANEUVERS, INSTRUCTOR (MARK FRISKEL) ACTIVATED THE AIRCRAFTS HYDRAULIC TEST SWITCH TO SIMULATE A HYDRAULIC FAILURE.  PILOT ^PRIVACY DATA OMITTED^ THEN SLOWED AIRCRAFT TO APPROXIMATELY 55-60 KTS.  FOLLOWING THIS, INSTRUCTOR THEN DE-ACTIVATED THE AIRCRAFT HYDRAULIC TEST SWITCH AND TOLD PILOT TO ACTIVATE THE HYDRAULIC ISOLATION SWITCH.  FOLLOWING THE HYDRAULIC ISOLATION SWITCH BEING ACTIVATED, THE PILOT SLOWED THE AIRCRAFT APPROX 10 KNOTS AND BEGAN PUSHING THE CYCLIC FORWARD AND TO THE RIGHT APPLIED RIGHT PEDAL.  PILOT STATED THAT HE COULD NOT MAKE LATERAL CYCLIC INPUTS.  INSTRUCTOR THEN TOOK CONTROLS AND STATED HE COULD NOT MAKE LATERAL CYCLIC INPUTS EITHER.  (AT THIS TIME, PILOT WAS STILL ON CONTROLS AS WELL).  INSTRUCTOR THEN CALLED FOR THE HYDRAULICS TO BE TURNED ON AS THE AIRCRAFT HIT THE GROUND IN AN APPROXIMATE 15-30 DEGREE, NOSE LEFT ATTITUDE.
