What happened
The incident occurred during the descent phase of a flight approaching the Rio de Janeiro seaplane base. At the time, conditions were severe, characterized by heavy rainfall and strong winds. The aircraft, identified as Marimba, struck the slope of a mountain within the Serra do Sambê range. This location is situated approximately 60 kilometers northeast of Rio de Janeiro. As a result of the impact, all 10 occupants on board were killed.
Findings
The official investigation determined that the accident was caused by controlled flight into terrain. The primary factor was poor visibility resulting from heavy rain during the descent. High winds were also noted as a potential contributing element to the loss of control or deviation from the intended path.
