What happened
The flight was forced to attempt an emergency landing in the vicinity of Big Prairie. The specific reasons necessitating this action were not identified in the available records. During the landing sequence, the three-engine aircraft made contact with trees. This impact resulted in significant structural failure, specifically causing the left wing to be torn from the airframe. All occupants sustained injuries during the event, and the airplane was declared damaged beyond repair.
Findings
The source material does not provide specific contributing factors or a formal conclusion regarding why the emergency landing was required. The primary mechanical consequence noted was the loss of the left wing due to the collision with vegetation.
