1958 Aviaco SNCASE Languedoc crash

The accident aircraft was SNCASE Languedoc msn 28, registration EC-ANR.^[1]

The aircraft departed from Vigo Airport at 15:40 local time on 4 December 1958 bound for Barajas Airport, Madrid. At 17:15, the aircraft was instructed to contact the control tower at Barajas and remain at Flight Level 95. In the next five minutes, the aircraft crashed into the 1,999-metre (6,558 ft) high La Rodilla de la Mujer Muerta mountain, in the Guadarrama Mountains. All five crew and seventeen passengers on board were killed.^[1] The search for the aircraft was hampered by inclement weather, with fog, snow, high winds and torrential rain reported.^[2]

The cause of the accident was that the pilot flew too low whilst trying to descend out of icing conditions. A navigational error may also have contributed to the accident.^[1]
