A Gol Transportes Aereos Boeing 737-700, registration PR-VBW performing flight G3-1003 from Rio de Janeiro Santos Dumont,RJ to Sao Paulo Congonhas,SP (Brazil) with 102 people on board, was climbing out of Santos Dumont’s runway 20R when white smoke developed in the cabin prompting the crew to stop the climb at about 7500 feet and return to Santos Dumont for a safe landing on runway 20L about 10 minutes after departure.

The airline reported hydraulic fluid vapors entered the cabin through the ventilation system. Four passengers were checked at the medical station and released, there were no injuries.
