After landing the Bell 206B JetRanger helicopter, serial number 381, at a private campground near Nordegg, Alberta, the pilot rolled the throttle to idle, tightened the cyclic and collective friction controls, and briefed the fixed-wing pilot who was sitting in the left seat to hold the left-side dual controls steady. The helicopter pilot then exited the helicopter, without shutting down the engine, and ran approximately 150 feet to a recreational trailer. As he was returning to the helicopter, he stopped briefly to talk to the campground caretaker who was standing approximately 100 feet to the left of the helicopter. Immediately, thereafter, a clunking sound similar to that of an out-of-balance washing machine was heard and the helicopter began to rock fore and aft on the skids. The main rotor disc was observed to be tilted to the extreme forward position. The pilot ran back to the helicopter, ducked under the main rotor disc from the left side, ran around the front of the helicopter, and climbed into the right seat. He immediately attempted to stabilize the helicopter by applying collective and increasing rotor speed. The oscillations diminished initially and then increased dramatically when the weight was reduced on the skids. The pilot then lowered the collective and shut down the engine. When he applied the rotor brake after shutdown a loud "clunk" was heard before the rotor blades stopped turning. Examination determined that the swashplate drive collar set and both main rotor pitch links were fractured. None of the four occupants on board the helicopter sustained injury.
