Incident
The twin-engine aircraft departed Porto Alegre at approximately 1100 local time bound for São Borja. The flight was conducted under an IFR flight plan at an altitude of 4,500 feet. A few minutes after departure, the captain requested to continue under VFR when he encountered poor visibility. The aircraft, named 'São Pedro do Rio Grande', was flying in clouds when it struck the slope of Cerro Cortelini near São Francisco de Assis.
Occupants
All 12 occupants were killed in the accident. Among them were Gustavo Ernesto de Carvalho Kraemer, captain and founder of Sociedade Anônima Viação Aérea Gaúcha (SAVAG), and Joaquim Pedro Salgado Filho, senator and former Minister of Aviation. They were returning to São Borja after visiting the site of a Panair Constellation crash that had occurred two days earlier.
Probable Cause
The official probable cause of the accident was determined to be controlled flight into terrain.
