At 19:41 local time the Robinson R44 Raven II helicopter departed a farm 6 nautical miles south of Eaglesham/Delta Tango Field Aerodrome, Alberta, on a night visual flight rules flight to DeBolt, Alberta, approximately 30 nautical miles to the south-southwest. The pilot and 3 passengers were on board. At approximately 19:54 the helicopter collided with terrain 10 nautical miles southwest of Eaglesham, Alberta (25.5 nautical miles northeast of DeBolt). The 4 occupants were fatally injured. The helicopter was destroyed and there was a post-impact fire. An emergency locator transmitter signal was received by the search and rescue satellite system.
Findings as to causes and contributing factors
- The pilot departed into weather that was forecast to be below the limits required for a night visual flight rules flight and, as a result, there were limited external visual cues available to the pilot during the flight.
- The decision to depart for the occurrence flight was likely a result of the pilot’s mental model that weather conditions were suitable based on his assessment of the weather products he accessed.
- The success of the short repositioning flight over the nearby Eaglesham/Delta Tango Field Aerodrome likely reinforced the pilot’s mental model regarding the suitability of the weather and influenced his decision to depart on the occurrence flight.
- As a result of the limited external visual cues, the pilot became spatially disoriented while en route and lost control of the helicopter, and the helicopter collided with the ground.
