What happened
A twin-engine aircraft departed from Resende Airport carrying a total of sixteen people, including four crew members and twelve paratroopers. Shortly after the flight commenced, the twelve passengers exited the aircraft via parachute. The remaining crew continued the flight toward Guaratinguetá Airport.
During the descent toward the destination, air traffic control notified the crew of unfavorable weather at Guaratinguetá and advised them to divert to São José dos Campos Airport. In response to this instruction, the crew began a go-around maneuver. However, during this process, the aircraft was turned in the incorrect direction. This maneuver resulted in the aircraft impacting the slope of Mt Alto Cerco, which sits at an elevation of 1,500 meters, approximately 30 km north of the original destination. The impact caused the total destruction of the aircraft, and all four occupants on board were killed.
Findings
Investigation into the accident indicates that the crew failed to follow the published go-around procedure during the diversion attempt, leading to the fatal collision with the terrain.
