Eastern flight 980 was a scheduled flight from Asuncion (ASU), Paraguay to La Paz (LPB), Bolivia.
The aircraft had reported crossing the DAKON intersection, 55 NM southeast of La Paz, at 25,000 ft. MSL. They were then cleared by La Paz ATC to descend to 18,000 feet, and the crew acknowledged this clearance. Although the Boeing 727 was supposed to be approaching La Paz along airway UA 320, on a 134° radial from the La Paz VOR, it veered significantly off course beyond DAKON; perhaps because the crew were maneuvering to avoid weather in the vicinity. The aircraft impacted the 19,600-ft. level of Mt. Illimani, a 21,000-ft. Andean peak, approximately 26 NM from the La Paz VOR/DME and 25 NM from La Paz runway 09R. Dark night, weather, and lack of visual references in the area all contributed to the crew’s inability to see and avoid the high terrain in their path.

A climbing expedition was organized the following summer to retrieve the flight recorders. The expedition reached the crash site and was able to dig through accumulated snow and examine the wreckage. However, bad weather and altitude sickness forced the expedition to turn back without recovering the recorders.
Early June 2016 an expedition found parts of the aircraft's cockpit voice recorder and flight data recorder containers. Magnetic tape segments that were recovered were not the ¼-inch width tape from a cockpit voice recorder or flight data recorder.
