During the November 27, 1956 operation of the flight, by a Lockheed L-749 Constellation, registration YV-C-AMA and named Jose Marti, the aircraft, piloted by French captain Marcel Combalbert, crashed into a mountain near Caracas, Venezuela.

It was approximately 18 kilometers from the runway when the aircraft struck the southern ridge of Cerro El Ávila at an altitude of 6700 feet.

[2] The probable cause of the crash was described thus: "The instrument flight training manuals show that the Linea Aeropostal Venezolana has approved a procedure for entering Maiquetia in semi-IFR conditions.

This procedure consists (of) maintaining a minimum flight level of 10,000 feet as far as the station (Miq 292.5), then turning north over this point and continuing on a 360º heading for 4 minutes, followed by a standard let-down to 1,200 feet above sea level until contact is established, and a return to the aerodrome under VFR.

It is obvious that the pilot-in-command did not fully comply with this procedure, and, after accumulating errors in estimating his speed, endeavoured to make a direct approach which proved fatal because his altitude at the time of his last report was insufficient to cross the Avila mountain range, against which the impact occurred.
