Narrative:
The pilot, accompanied by a helicopter safety lead (HSL) (assisting to secure the bambi bucket), took off from Tulbagh Forestry Station for a fire-fighting operation in the Bainís Kloof Pass area. According to the eye witness the incident commander (IC) there was a truck approaching on the R301 from Wellington, which was successfully stopped at a safe from the temporary landing zone on which the helicopter intended to land. At the time, the helicopterís approach was uneventful and it hovered at a distance of 50 m before the temporary landing zone which was used by ZS-HBU on the R301 regional road. The spotter pilot reported that he saw the helicopter pitching up a few metres and rolled to the left with its tail low. The helicopterís main rotor blades made contact with terrain before it crashed and came to rest on its left-hand side.
The helicopter was destroyed by impact forces, post impact fire (which was successful extinguished by the other helicopter and ground fire fighters) and later on by the veld fire.


Probable Cause/s
The helicopterís main rotor blades made contact with the terrain during an attempt to abort the landing resulting in a loss of control and crashed.
Contributory
a) A cross wind component of 12-15kt, and
b) Loss of tail rotor effectiveness.
