This is the type of plane that the Andes survivors used in their flight that never got to their destiny. This type of aircraft has the characteristic of flying with the tail lower than the nose. Its maximum of altitude is 6800 m and its maximum speed 437 km / h. The airplane was in perfect technical conditions, which means the accident was caused by human error. However, there was an important change in the direction and strength of the winds which meant the Fairchild couldn’t see cruising speed reduced by a 15%, from 210 to 180 knots. Because this was not considered like a crucial variable, a navigation mistake was committed.
