What happened
On 28 June 2024, a Bell 212 helicopter, operated by Great Slave Helicopters 2018 Ltd., was engaged in wildfire suppression operations near Fort Good Hope, Northwest Territories. Following its departure from Fort Good Hope Airport (CYGH), the aircraft suffered a sudden and severe mechanical failure. A main rotor blade detached from the rotor head, which was immediately followed by the separation of the remaining blade and the rotor head from the mast. This sequence of events caused the helicopter to crash into the ground, leading to a post-impact fire.
The investigation
The TSB investigation focuses on the mechanical failure that occurred during the flight. Investigators are examining the structural integrity of the rotor system and the circumstances surrounding the separation of the rotor components from the mast.
