Circumstances:
The aircraft left São Paulo-Congonhas Airport in the morning on a flight to Londrina with an intermediate stop in Jacarezinho. En route, the on board ADF system failed and the captain (aged 23) decided to return to Congonhas. But the operations forced the crew to continue the flight. Few minutes later, weather conditions worsened and the visibility was very bad due to low clouds and heavy rain falls. While cruising at an insufficient altitude, the aircraft hit the slope of the Serra dos Ruvina located near Ribeirão Claro. Two passengers, a woman and her kid aged 5 were rescued while all 20 other occupants were killed.
Probable cause:
It was determined that the captain was imprudent and showed a lack of discipline in continuing the flight in VFR mode in IMC conditions (poor visibility due to low clouds and heavy rain falls). Nevertheless, experts retained some responsibilities against the head of the operations who disallowed the pilot to return to Congonhas Airport and 'forced' him to continue the flight in spite of the poor weather conditions.

Circumstances:
The aircraft left São Paulo-Congonhas Airport at 1123LT bound for Porto Alegre. Some 20 minutes prior to the estimated time of arrival, a fire in cargo hold 'G' was noted. The pilot executed an emergency descent while the mechanics tried, in vain, to extinguish the fire. The flight crew members were not able to see their instruments due to heavy smoke and had to keep their heads out of the window to carry out an emergency landing in hilly terrain. The passengers crowded in panic at the forward end of the cabin in an attempt to escape from the fire. This caused a dangerous and sudden change in the Centre of Gravity of the plane. The aircraft swung violently during the landing on rough ground.
Source: ASN
Probable cause:
The cause of the fire in the Hold 'G' of the airplane was not determined by the investigation board who evidently assumed that several possibilities may have existed such as the ignition of inflammable material contained in cargo or passenger baggage, or through a live cigarette butt falling through an open cargo tie ring hole or open rivet hole in the cabin floor - considered a very remote possibility. The report states that several passengers, possibly students on board brought petroleum jars from Bahia, and some suspicion is expressed related to this incident.
