A four-engine aircraft on descent to Copenhagen crashed into the Øresund while intercepting the ILS for runway 22L. Three passengers were rescued; 31 occupants were killed. Later, one survivor died from injuries.

Incident Overview

An aircraft operating a flight from Oslo to Copenhagen crashed into the Øresund near Saltholm Island during its final approach to Copenhagen-Kastrup Airport. The crew had begun descent in marginal weather conditions and received clearances to descend to 5,000 feet and subsequently to 1,500 feet. While attempting to intercept the ILS for runway 22L, the aircraft nosed down and plunged into the water.

Occupants and Survivors

The aircraft carried multiple crew members: pilot Dezsö Szentgyörgyi, copilot Jozsef Menyhart, navigator Pál Jancsovics, radio operator Károly Lantos, flight engineer Lázlo Aladi, and stewardesses Klara Tolnai, Eva Margit Ivan, Janosne Szalay, and Katalin Tamasne. Out of the occupants, three passengers were rescued. The remaining 31 occupants were killed in the accident. Three days later, one of the survivors succumbed to injuries sustained in the crash.

Official Findings

The probable cause of the accident was determined to be a loss of control of the aircraft at the moment it was about to intercept the ILS glideslope to runway 22L. While the precise cause of the loss of control could not be established, the investigation concluded that it is most likely that the aircraft, while in landing configuration, experienced a deterioration of airflow over the tailplane to such a degree that longitudinal stability was lost.
