Circumstances:
Following an uneventful flight from Helsinki-Vantaa Airport, the crew started a night approach to Seinäjoki-Ilmajoki Airport. On short final, the crew failed to realize his altitude was too low when the aircraft struck trees, stalled and crashed in a wooded area located 800 meters short of runway 32. Both pilots and four passengers were killed while six other occupants were injured. The aircraft was destroyed. There was no fire. At the time of the accident, the RVR for runway 32 was 1,200 meters with a vertical visibility of 300 feet.
Probable cause:
The immediate cause of the accident was the decision to continue the NDB approach in difficult visibility circumstances. The airplane descended below minimum altitude without the required visual contact with approach lights or the runway. Contributory factors were the airline's poor safety culture due to pressures of performance, highlighted by the pilot because of his personality structure.
