[2][3][6][7] The Embraer EMB-110P1 Bandeirante twin turboprop aircraft, registration PT-SEA and serial number 110352, was carrying twenty-eight people, though it was certificated for twenty-one.

[2][4] Shortly before the crash, the pilot reportedly attempted to turn back to Coari due to heavy rainfall, but then had to make an emergency landing at an abandoned runway of the city of Manacapura.

The four survivors (three adults and one nine-year-old child), who were sitting at the rear of the plane, managed to open an emergency exit and reach the surface; they did not suffer major injuries.

Unable to maintain level flight on a single engine in its overweight condition, the aircraft crashed while attempting to execute an emergency landing.

[1] CENIPA noted that when the pilot in command contacted Amazonic Center air traffic control by radio, he reported 20 persons on board, instead of the actual 28.
