From the Wikipedia article
The Lloyd Aéreo Boliviano mid-air collision occurred on 5 September 1955, when two aircraft (a Douglas DC-3 and a Boeing B-17) of Lloyd Aéreo Boliviano collided in mid-air over Cochabamba. The B-17 fell out of control and crashed to the ground, killing its three crew members, while the DC-3 made an emergency landing in Trinidad, with no injuries reported among the 11 people on board.
Investigation and cause
Investigation
The exact cause of the accident was not established with certainty. No conclusive official reports were found publicly available. The evidence suggests that there may have been contributions from weather conditions (cloud cover), speed differences between the two aircraft, or possible failures in air traffic control coordination.
The lack of flight data recorders or voice recorders, typical of the era, limited the depth of the investigation. It is unknown whether the Directorate General of Civil Aeronautics of Bolivia issued any official report or recommendations after the accident.
