A twin-engine aircraft crashed into the Beagle Canal near Ushuaia in marginal weather, killing all 12 occupants, including the Governor of Tierra del Fuego.

Flight Details and Accident Sequence A twin-engine aircraft departed Buenos Aires-Aeroparque-Jorge Newbery Airport for Ushuaia, with an intermediate stop at Río Grande Airport. The flight carried two pilots and 10 passengers, including the Governor of the Province of Tierra del Fuego. After two passengers disembarked and two others boarded at Río Grande, the aircraft took off at 1638LT for the final leg to Ushuaia. During the approach to Ushuaia Airport, the crew encountered limited visibility due to snowfall. While on final approach in instrument meteorological conditions, the captain elected to continue under visual flight rules. The aircraft subsequently struck the water surface and crashed in the Beagle Canal, approximately 9 km east of the airport. The aircraft sank, and all 12 occupants were killed. ## Occupants The crew consisted of Mario Marconcini, pilot, and Rodolfo Pourrain, copilot. The passengers were: Ramón Alberto Trejo Noel, Governor of the Province of Tierra del Fuego; Mrs. Ofelia Olga Lisa, the Governor’s spouse; Dr. Ernesto Julio Löffler; Roberto Luis Campanella, Minister of Public Health and Social Action; Fernando Diego García, Minister of Economy; Ricardo Luis Sica, private secretary to the Governor; Guillermo Marcilese, General Secretary; Carlos Alberto Lisa, assessor; Nora Ormiston, assessor; and Pedro Alberto Altuna.
