On July 4, 1949, a Noorduyn Norseman (registration CF-GHY) operated by Yellowknife Airways was involved in an aviation accident near Yellowknife, Canada during takeoff. No fatalities were reported. Investigators recorded the probable cause as: An aerodynamic stall occurred during the initial climb phase immediately after takeoff. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 2 related events involving the same aircraft type or operator are linked below.
A single-engine aircraft suffered a stall immediately after takeoff, resulting in a fiery crash that injured all three occupants and destroyed the airframe.
What happened
The incident occurred shortly after the single-engine aircraft left the ground. While executing the initial climb phase of flight, the machine experienced an aerodynamic stall. This loss of lift caused the aircraft to descend rapidly and impact the terrain, where it subsequently caught fire. The post-accident inspection confirmed that the airframe was completely destroyed by the impact and subsequent flames. All three individuals on board sustained injuries in the event.
Findings
The source material indicates that the primary sequence of events involved a stall occurring during the initial climb segment immediately following liftoff. No further specific mechanical or environmental contributing factors are detailed in the provided text beyond this immediate aerodynamic failure.
Probable cause
An aerodynamic stall occurred during the initial climb phase immediately after takeoff.
