Circumstances:
The airplane departed Arica on the return flight at approximately 1327 hours Bolivian time. It was to be an eight-hour, VFR flight, and the aircraft was to cruise at 17,000 feet. Eight minutes after take-off the crew advised ATC at Cochabamba of the departure time, the number of passengers on board, the aircraft's weight and the amount of fuel being carried. Between 1347 and 1348 the air traffic controller at La Paz advised that Panagra flights 701 and 393, flying at 22,000 and 21,000 feet were estimating Charaña at 1355 and Arica at 1351 respectively. Flight 915 acknowledged the message. ATC at La Paz called the flight at approximately 1400 hours, and several times thereafter, to report on the new positions of the two Panagra aircraft, which were in the Arica zone but received no reply. It was determined subsequently that the aircraft crashed into Chachacomani Peak (latitude 17°49'00'', longitude 69°50'00''W) in Peruvian territory near the Chilean border at an altitude of 14,250 feet, sometime between 1351 and 1355. The wreckage was spotted by the crew of a reconnaissance aircraft few hours later and the first rescuers arrived on scene later to confirm that all 39 occupants have been killed.
Probable cause:
A flight under visual flight rules was attempted below the minimum altitude indicated in the flight plan in weather conditions that were marginal for this type of operation and were associated with the severe turbulence which usually exists in that region (western area).

Circumstances:
Few minutes after takeoff from Cochabamba-Jorge Wilsterman Airport, while climbing to an altitude of 9,000 feet, the captain informed ATC that an engine exploded. Shortly later, the airplane went out of control and crashed in Laguna Huanacota, about 13 km south of the airport. A young girl aged two was seriously injured while all 58 other occupants were killed. While being evacuated to the hospital, the only survivor died from her injuries.
Probable cause:
Investigations believe it is probable that the engine would have exploded due to its excessive contribution. At the time of the accident, the total weight of the aircraft was greater than the maximum allowable take-off weight, which remains a factor contributing to the engine explosion.
