Accident Overview
A cargo flight operating from Helsinki to Joensuu ended in a crash during the landing phase. The aircraft was on a descent to Joensuu Airport when it encountered poor visibility due to snowfall. While on final approach, the pilot lost control of the aircraft, which subsequently crashed approximately 7 kilometers from the airport. The aircraft was destroyed in the impact, and the pilot, the sole occupant, was killed.
Flight Details
The flight from Helsinki was described as uneventful prior to the descent. Weather conditions at the time included snowfall, which reduced visibility. The pilot initiated the approach without the aid of an automatic pilot system, as the aircraft was not equipped with one. Additionally, a navigational beacon at Joensuu Airport was reported to be unserviceable at the time of the accident.
Investigation Findings
The official investigation determined that the loss of control occurred after the pilot suffered spatial disorientation while completing the approach in poor visibility. Additional findings included limited visibility due to snowfall, the absence of an automatic pilot system in the aircraft, and the unserviceable beacon at Joensuu Airport.
Probable Cause
The official probable cause of the accident is that the pilot experienced spatial disorientation during the approach in poor visibility, which led to a loss of control and subsequent crash.
