Narrative:
The DC-6, named "Mariano Moreno", was on a flight from Asuncion to Buenos Aires when the plane suddenly crashed in a field near Salto, Uruguay.

Probable Cause:

PROBABLE CAUSE: "The immediate cause of the accident was overspeeding of No.3 propeller caused by irregular operation of the propeller governor, detachment of that propeller and impact with that of No.4 engine, followed by disintegration of the aircraft. The remote cause of the accident was insufficiently strickt observance of engine maintenance conditions, because, while Pratt and Whitney Service Bulletins Nos. 1666 and 1680, dated 5 November 1957 and 15 May 1958 respectively, are not mandatory, the company should have taken account of the special circumstances in the history of No.3 engine, which resulted in the destruction of LV-ADS."

Classification:
Failure to follow AD and SB's
Prop/turbine blade separation
Loss of control
