The Robinson R22 Alpha helicopter (registration N97CP, serial number 0421) departed Toronto City Centre Airport, Ontario, on a short flight to the pilot's private helipad in the rural town of Norval, Ontario. At 20:00 Eastern Daylight Time, in the hours of darkness, the helicopter crashed 1.8 nautical miles northeast of the final destination. The helicopter erupted into flames at impact and was partially consumed by a post-crash fire. The pilot was fatally injured.
Findings as to Causes and Contributing Factors
1. It is likely that, while attempting to apply carburetor heat, the pilot inadvertently pulled the mixture control knob to the idle cut-off position, causing the engine to shut down.
2. It is likely that the plastic guard had not been placed over the mixture control knob, resulting in the pilot being able to pull the control to the cut-off position.
3. Following the engine shutdown, the rotor rpm was allowed to decay, resulting in a loss of control and uncontrolled flight into the terrain.
4. With few visual references, the pilot likely became spatially disoriented, contributing to the inability to maintain control.
