What happened
A twin-engine aircraft was conducting a geophysical survey mission for a mining enterprise when it crashed into a mountain slope. The flight originated from Pucallpa and was equipped with enough fuel to sustain approximately 10 hours of flight time. Roughly two and a half hours after takeoff, air traffic control detected a short-duration signal from the aircraft's emergency locator transmitter.
Following the detection of the signal, search and rescue operations were launched to locate the missing plane. A helicopter crew eventually discovered the wreckage on a mountainside, noting that the debris was burnt. The accident resulted in three fatalities, with no survivors among the occupants.
Findings
While the specific mechanical or environmental triggers for the crash were not detailed, the discovery of burnt wreckage indicates a significant post-impact fire. The flight was in the en route phase of operation when the emergency signal was transmitted.
