Whilst en route the engine chip detector caution light came on. The pilot elected to make a precautionary landing but, because he misread the wind direction, he commenced the approach with a tailwind component. The helicopter began to overshoot the planned landing site and was approaching cliffs.

The pilot therefore increased the rate of descent and the helicopter touched down hard at high speed. The subsequent inspection found two metal fragments on the chip detector but was unable to find any problems with the engines. No injuries reported to the 4 person on board (pilot and 3 passengers)

Later repaired and sold in Germany as D-HAAP with Rotorflug GmbH in October96
