AN AEROSPATIALE AS350D HELICOPTER COLLIDED WITH TWO POWER TRANSMISSION CABLES IN MOUNTAINOUS TERRAIN WHILE PREPARING TO LAND AT AN OFF-AIRPORT SITE. THE HELICOPTER WAS NOT SCHEDULED TO LAND AT THE SITE AND THE PILOT HAD NOT LANDED AT THE SITE IN THE PAST. HIGHER MOUNTAINOUS TERRAIN IN THE AREA MASKED THE UNMARKED WIRES AND SUPPORT TOWERS. THE POWER TRANSMISSION CABLES WERE DEPICTED ON THE AERONAUTICAL SECTIONAL CHART AND WERE NOT REQUIRED TO BE MARKED.
Probable Cause: THE PILOT-IN-COMMAND'S INADEQUATE IN-FLIGHT PLANNING AND INADEQUATE VISUAL LOOKOUT. FACTORS IN THE ACCIDENT WERE MOUNTAINOUS TERRAIN WHICH MASKED THE PRESENCE OF THE WIRES AND THE PILOT-IN-COMMAND'S LACK OF FAMILIARITY WITH THE GEOGRAPHIC AREA.
