What happened
During an approach to land on the Rio Purus near Canutama, a seaplane entered the water in an incorrect attitude. The aircraft was noted to be in a nosed-down position upon impact, which caused it to become partially submerged in the river.
The accident resulted in four fatalities among those on board. Following the impact, rescue efforts were successful in saving the remaining 10 occupants, who were pulled from the wreckage or the surrounding water.
Findings
Initial observations of the wreckage indicate that the aircraft's descent angle was a critical factor during the landing sequence. The nose-down attitude of the plane at the moment of contact with the river surface led to the partial submersion of the vessel.
