Circumstances:
On approach to Rio de Janeiro following a cargo flight from Vitória, the crew encountered technical problems and was forced to lower the gear manually.

During the last turn, the aircraft stalled and crashed into the Guanabara Bay. All three crew members were injured while the aircraft was lost.
Probable cause:
It was determined that the loss of power on both engines was caused by the failure of the hydraulic system.

Circumstances:
The twin engine aircraft left Porto Alegre around 1100LT bound for São Borja with an IFR flight plan filed at an altitude of 4,500 feet.

All 12 occupants were killed, among them Gustavo Ernesto de Carvalho Kraemer, captain and founder of the Sociedade Anônima Viação Aérea Gaúcha (SAVAG) and Joaquim Pedro Salgado Filho, senator and ex Minister of Aviation. They were returning to São Borja after they visited the site where a Panair Constellation crashed two days earlier.
Probable cause:
Controlled flight into terrain.

Circumstances:
En route from Vitória da Conquista to Salvador, the crew encountered poor weather conditions and the captain decided to reduce his altitude to avoid clouds when the aircraft went through a cumulonimbus area. Severe turbulences were encountered and the aircraft went out of control when both wings broke off and separated. The aircraft dove into the ground and crashed in the region of Ilhéus. Two passengers were seriously injured while 13 other occupants were killed.
Probable cause:
It was reported that the aircraft encountered severe turbulences while cruising in a cumulonimbus area, which caused the rupture of both wings that were overstressed (above wing certification). The decision of the crew to start a rapid descent and to fly into a cumulonimbus area was imprudent.
