What happened
On the second leg of a journey toward Lima, a twin engine airplane departed from San Ramón-Capitan Alvarino Airport at 17:30 local time. The flight was carrying a total of 57 passengers and five crew members, along with various cargo including animals and wood products.
During the initial climb phase, the pilot notified air traffic control regarding mechanical issues involving the engines and reported an inability to hold the requested altitude. Approximately ten minutes after the departure, the aircraft collided with a mountain slope situated roughly 30 km northwest of Tarma. The impact caused the plane to break apart, and all 62 fatalities were recorded.
Findings
Investigations into the accident revealed that the aircraft was operating significantly over its capacity, as it carried 57 passengers despite having a maximum certification of only 44. The investigation concluded that the primary reason the plane could not reach the necessary altitude was excessive weight from the passenger and cargo load, combined with the crew's inability to achieve full engine performance due to strong atmospheric contributions.
