What happened
Following its departure from Fort Nelson, a single-engine aircraft experienced significant issues maintaining necessary altitude. During the climb, the plane made contact with trees and subsequently came to rest in a forested region. The impact resulted in the total destruction of the airframe. Both individuals on board, comprising the pilot and one passenger, sustained two serious injuries during the accident.
Findings
Investigations into the crash revealed that the aircraft's inability to climb was caused by heavy ice and frost accumulation on critical flight surfaces, specifically the wings, elevators, and tail assembly.
