What happened
During a flight through adverse weather, an aircraft struck the side of a mountain located near Aklavik. The impact occurred approximately 50 feet below the peak of the mountain, which was obscured by heavy cloud cover at the time. The wreckage was discovered several hours after the incident. All three crew members on board sustained injuries during the crash but were successfully evacuated from the site.
Findings
Investigations into the accident revealed that the flight deviated from its intended path because the crew did not adhere to the route specified in their flight plan. This deviation was caused by reliance on inaccurate information from a local NDB. The navigational aid's parameters were frequently unreliable due to the surrounding terrain and atmospheric turbulence, a factor that the crew was unaware of during the flight.
