Narrative:The pilot of a Hayes Bell 206B helicopter encountered heavy fog and lost visual reference during a local VFR flight near Nitnat on Vancouver Island. The pilot lost control and the helicopter entered vortex-ring state and the nose pitched down rapidly. During the pilot's subsequent recovery actions, the nose attitude changed to extreme nose-high, resulting in an overtorque and airframe/transmission damage. The pilot then descended, broke out from the base of the cloud, cleared the terrain, regained visual reference and landed the helicopter in a clearing without further event. There was no injury.
