Tuesady, August 29, 1995 10:00 PDT

NTSB Narrative Summary Released at Completion of Accident

THE FLIGHT INSTRUCTOR SAID THE 50-HOUR STUDENT PERFORMED A SLOPE LANDING IN A FLOOD CONTROL DAM AREA USED FOR PRACTICE LANDINGS. DURING THE TAKEOFF, THE STUDENT LIFTED THE LOW SKID WITH CYCLIC; HOWEVER, CONTINUED TO APPLY THE CONTROL AND THE HELICOPTER STARTED TO ROLL BEYOND LEVEL. THE INSTRUCTOR STATED THAT SHE ATTEMPTED TO APPLY CORRECTIVE CONTROL INPUTS BUT THE STUDENT OVERPOWERED HER. THE HELICOPTER CONTINUED TO ROLL UNTIL THE MAIN ROTOR STRUCK A 4-FOOT-TALL STEEL POST. THE HELICOPTER THEN ROLLED OVER.

NTSB Probable Cause Narrative

the student's improper use of the cyclic control; the flight instructor's inadequate supervision of the flight; and the flight instructor's failure to maintain an adequate obstacle clearance distance in selection of a practice slope landing area.
