Austral Líneas Aéreas Flight 205 was a regularly scheduled domestic Austral Líneas Aéreas flight operating a route between Buenos Aires and Mar del Plata in Argentina that crashed after encountering poor weather conditions during landing on 16 January 1959, killing 51 of the 52 passengers and crew on board.

[1] The Curtiss C-46 Commando, registration LV-GED, took off from Buenos Aires at 19:50 local time with five crew members and 47 passengers aboard for an approximately 250-mile flight to Mar del Plata.

[2] The sole survivor, businessman Roberto Servente, endured four hours in the sea and managed to swim to shore with multiple fractures and serious injuries.

In addition, the crew's mental state contributed to the subsequent stall and loss of control that caused the aircraft to crash.

Contributing factors were the non-functioning radio beacon and the poor visibility which made discerning the airport's lights and runway difficult.
