The pilot and passenger in a Custom Helicopters Bell 206 were on a power line maintenance flight about 30 NM southeast of Flin Flon, near Cranberry Portage, Manitoba,when the aircraft crashed and burned. Both occupants were fatally injured.
Finding as to Causes and Contributing Factors
1. The helicopter was hovering close to the power line tower structure and became entangled in the upper (non-energized) cable span. As a result, the helicopter became uncontrollable, collided with the tower structure, and crashed.
Finding as to Risk
1. The operator did not have training procedures specific to helicopter operations in the vicinity of power lines and did not have a procedure for reporting hazardous operating conditions. Such programs could have reduced the risks associated with helicopter power line operations.
Other Finding
1. Manitoba Hydro did not have an audit procedure in place that might have identified the need for specialized training for helicopter operations specific to their contract requirements.
