The helicopter collided with terrain during a demonstrated hydraulic servo-control system failure. The check airman brought the helicopter to a hover with hydraulics off. The check airman experienced a gust of wind which pitched and yawed the helicopter onto the right side of the fuselage. A Review of the Eurocopter training syllabus for the AS 350 B1/B2, states in simulated hydraulic servo-control system failures, the "HYD TEST" button should be used when conducting this procedure; and discussion and/or demonstration should be performed in cruise flight at approximately 90 knots. The Gainesville 1900 weather observation reported visibility 10 statue miles, wind direction 310 degrees, wind speed 17 knots, gust 23 knots.
Probable Cause: The check airman's failure to follow prescribed procedures that resulted in the lost of control and subsequent in-flight collision with the terrain. A factor was gusting wind conditions.
