On September 22, 2006, about 1200 eastern daylight time, a bell 212 helicopter, Colombian registration HK-3341, crashed while making an emergency landing near San Vicente, Colombia, while on a positioning flight. Visual meteorological conditions prevailed at the time and a visual flight rules flight plan was filed. The aircraft was destroyed, one passenger received fatal injuries, and the pilot and co-pilot received serious injuries. The flight originated from Yopal, Colombia, the same day, about 1033.

The pilot stated that while in cruise flight at 9,500 feet msl, near San Vicente, Colombia, they heard a loud noise from the main transmission area. They were flying at 100 KIAS at this time. Upon hearing the noise they immediate felt a very violent vibration in the cyclic control. They reduced the collective control and the vibration reduced greatly. They then reduced the engine throttles to idle and entered an autorotation. As they descended near the ground they noticed the main rotor rpm was slowing. As they prepared for touchdown he pulled up on the collective control and the aircraft touched down with near zero forward speed. Examination of the accident site by Colombian Authorities and a representative of Bell Helicopter showed the helicopter touched down hard in a near vertical descent. The landing gear skids collapsed and the fuel tanks ruptured. A post crash fire erupted and consumed the helicopter.


In the absence of evidence of damage or failure to the aircraft's main rotor cyclic and collective control systems, or the main rotor system, and the finding of non-compliance with the speed limit described in the aircraft RFM limitations chapter, it is established that the crew's failure to comply with the indicated speed limitations during descent resulted in the loss of the tail rotor control and loss of control.
The loss of the main rotor speed during descent was the result of an unsuitable combination of bus reduction and closing the throttles to the idle position, thus losing the ability to control the aircraft and to cushion the final part of the touchdown.
