A Delta Helicopters Bell 206L-1, registered as C-GEOM, was en route northwest of Cold Lake at 700 feet agl when the low rotor rpm horn sounded. The pilot dropped the collective and observed that the rotor tachometer read zero and the turbine tachometer read 100 percent. A check of the collective produced no response on the rotor rpm; however a loss of hydraulics was noticed. An autorotation was initiated. On landing the main rotor blades struck the rear vertical fins and severed the tail rotor drive shaft. A post occurrence inspection revealed that the spline gear from the transmission to the tach generator had worn leading to a failure of the hydraulic pump.
