On June 5, 2007, about 1230 local time, a Colombian registered Bell 206L3 helicopter, HK-4400, operated by Aviheco LTDA, crashed under unknown circumstances in a mountainous region, at about the 1,000-foot level, in Simiti, in the Bolivar region, Colombia. Instrument meteorological conditions prevailed in the area at the time, and an instrument flight rules flight plan was filed. The pilot and copilot received fatal injuries, and 4 passengers received serious injuries. The helicopter incurred substantial damage. The flight originated at Barrancabermeja, Colombia, earlier that day.
According to an official with the Colombian DGAC, the helicopter was transporting persons in an area of hostile rebel activity, and it crashed under unknown circumstances. The official further stated that the aircraft came to rest in remote and difficult terrain, and plans are to recover it from this hostile rebel controlled area, to Bogota, Colombia, and thereafter conduct the investigation.
CAUSES
The erroneous or unintentional actuation of the fuel shut-off valve switch by a crew member during the cruise flight that shut down the turbine, forcing the execution of an emergency descent in auto-rotation to an unprepared field.
The inappropriate termination of the deceleration and grounding as a result of the late detection of high voltage cables that frustrated the pilot's planned maneuver and forced him to use the leveling to cross the obstacles.
The progressive destruction of the aircraft during grounding against wax palms that ended up causing fatal and serious injuries to the occupants.
A contributing factor to the injuries was the non-use of seat belts and the failure to attach communications equipment to the aircraft structure.
