The aircraft was completing a charter flight from Iquitos to Andoas on behalf of the Occidental Petroleum Company, carrying eight crew members and 80 employees of this company and their subcontractors. While descending to Andoas-Alferez FAP Alfredo Vladimir Sara Bauer Airport by night, the crew encountered poor weather conditions with rains falls and limited visibility. On final, the aircraft descended below the glide, collided with trees and crashed in a dense wooded area located 5 km short of runway 12. First rescuers arrived on site three hours later. Thirteen occupants included two crew members were seriously injured while 75 other occupants were killed.
Probable cause (official findings): For undetermined reasons, the crew descended below the minimum safe altitude during an approach in IMC conditions until the aircraft impacted the ground.
