The crash was the first and deadliest crash in the history of the airline, and it remains as the deadliest plane crash of the history of Ecuadorian aviation.

, in Cuenca, with 111 passengers and 8 crew members. Some minutes later, the crew experienced some bad weather conditions during the final approach to the airport, and they contacted to the Cuenca tower for permission to land the plane, which was granted. During the next few and final minutes of the flight, the pilots suffered from spatial disorientation, because they were preoccupied trying to find the runway in middle of a extensive fog, and did not understand some of the plane's controls. At around this time, the plane began to a controlled flight into terrain, towards a mountain.

Seconds later, and one mile from the airport, the crew realised that the plane was flying below the altitude given by the tower and then, in a desperate attempt to save the plane and its passengers, they elevated the nose in a high position and put full power, but it was too late. The jetliner scraped a mountain peak, exploded, and slid down a ravine coming to rest at the foot of a mountain, killing all 119 people on board instantly. When radio contact was lost for nearly two minutes, the Cuenca ATC declared an emergency. The next day, search aircraft and rescue workers were sent to the plane's last known position. Because of the remote area and the difficult access where the crash occurred, it took rescue personnel several hours to reach the site itself. After they reached the crash site, the investigation began to find the causes of the crash of the TAME Boeing 737. The plane was a total loss and it was written-off.

Investigation

An investigation was initiated by Ecuadorian authorities, with the support of Boeing, the NTSB, and Pratt & Whitney, which lasted for several months. The investigation concluded that the crash occurred due to human error and controversial factors: the pilot was unqualified and not trained properly by the company to fly the Boeing 737 Advanced, the crew was not very acquainted with the controls of the aircraft and when they were trying to find the runway in the middle of a fog, the crew experienced spatial disorientation and as a consequence, the plane entered into a CFIT in a mountainous region of Cuenca, just one mile of the runway and begun to fly below from the safest altitude level, without knowing of the pilots, until seconds from the crash.

Aftermath

When the report of the accident was shown in Ecuador, it caused public outrage. Questions were asked as to how a unqualified pilot was flying the plane without the necessary experience. TAME's reputation was damaged by these conclusions of the investigation, but it recovered from the tragedy by reinforcing and adding strict standards in the pilot training process and continues to become one of the best South American airlines that flies with good safety record and only a few minor incidents.
