Beschrijving:
BAC One-Eleven LV-JGY was one of three chartered aircraft flying from Buenos Aires to San Carlos de Bariloche. LV-JGY was, at 22:53, the second plane to depart from Buenos Aires. While climbing to the assigned cruising altitude of FL350, the airplane suffered pressurization problems. This forced the crew to request FL290. At 00:40 the flight was cleared to descend to FL200. Nine minutes later the crew requested and was granted a direct ILS approach. The ILS approach to runway 28 was discontinued because of problems with the ILS reception. The pilot then requested a visual runway 10 approach. Wind was 270deg/15 knots and the pilot decided to use ILS procedure no. 2 and try to land at runway 28 anyway. Last radio contact was when the pilot reported abeam the VOR beacon. The airplane collided with terrain near Cerro Pichileufú.

Probable Cause:

PROBABLE CAUSE; "The accident was caused by the collision of the aircraft with the ground during the final approach to Bariloche runway after an improper and premature descent which was below safety limits.
The accident can be attributed to a procedural error by the crew during the final approach in that they abandoned the ILS procedure, an action strongly and unduly influenced by the interruption of the VOR signal and also probably by the state of mind of the pilot-in-command."
