THE TAIL ROTOR 90 DEGREE GEARBOX MOUNTING FLANGE FRACTURED DURING APCH TO LAND, WHILE THE HELICOPTER WAS AT ABOUT 75 FT AGL. THE GEARBOX SUBSEQUENTLY SEPARATED FROM THE HELICOPTER. THE PLT INITIATED AN AUTOROTATION. THE HELICOPTER ROLLED OVER ON LDG. METALLURGICAL ANALYSIS INDICATED THAT THE FLANGE FAILED AS A RESULT OF EXTENSIVE PREEXISTENT FATIGUE CRACKING, AND THAT THE CRACKING WAS THE RESULT OF EXCESSIVE VIBRATION.
