Copilot / Total flying hours:
2737
Circumstances:
While approaching Vaasa Airport by night, the pilot-in-command completed a last turn to join the runway approach path when the airplane lost height, struck trees and crashed in flames in a dense wooded area located in Koivulahti, about 10,5 km from the airfield. The aircraft was destroyed and all 25 occupants were killed.
Causes:
The probable cause of the accident was the wrong execution of a left turn at low altitude at night, as a result of which the aircraft stalled, lost its maneuverability and went into a spin. Contributing factor: As a consequence of having had alcoholic drinks and insufficient sleep the night before the accident, the pilot was not considered to be in a satisfactory mental and physical condition to undertake the flight. For the same reason, the copilot should not have been allowed to start on the flight in question.
