Hughes 500C-369HS, G-ORRR
The pilot reduced speed as he approached the airfield, and almost immediately experienced erratic power fluctuations. He therefore entered an autorotation and attempted to clear some trees on the approach to his chosen landing site. At about 40 to 50 feet above the ground, the helicopter descended rapidly and as a result landed heavily and rolled on to its side. The pilot was uninjured. The investigation could not identify the cause of the power fluctuations.
