The privately owned Rotorway 162F, C-FLRQ, was enroute from the manufacturer’s facility in Red Deer, AB (CYQF), to a private strip near Big Valley, AB. In the vicinity of Delburne, AB, the FADEC controlled engine (RI162) began to lose power, and then came back on. The pilot decided to conduct an autorotation in a field. During touchdown, the helicopter flipped onto its right side. The helicopter was substantially damaged; the pilot, who was the lone occupant, was not injured.
