Narrative:
The helicopter crashed undertaking an agricultural crop survey. All five occupants were injured, two seriously, and another died in hospital from the injuries sustained in the crash.

During the survey flight the helicopter’s electronic engine control unit detected and recorded a number of faults, resulting in the ‘full authority digital engine control’ system changing to ‘fuel flow fixed’ mode. The fuel flow fixed mode resulted in the rotor speed varying beyond normal operating parameters. The pilot was not able to control the varying rotor speed and a forced landing ensued.

The helicopter struck the ground hard and remained upright, while the engine continued to produce high power.

This, combined with an imbalance in the rotor system from the ground impact damage, resulted in a severe shaking of the airframe, which destroyed the helicopter.

One occupant seated in the front-left position received fatal injuries. The pilot and one other occupant received serious injuries; the remaining two occupants seated in the centre of the cabin received minor injuries.
