Circumstances:
The landing at São Paulo-Congonhas Airport was completed in heavy rain falls. After touchdown on a contaminated runway, the airplane encountered difficulties to decelerate properly and as the end of the runway was imminent, the captain decided to veer off runway to the left. While contacting a waterlogged ground, the undercarriage were torn off and the airplane came to rest. All 88 occupants evacuated safely and the airplane was damaged beyond repair.
Probable cause:
The airplane suffered hydroplaning after landing on a wet runway. The braking coefficient was poor as there was an excessive accumulation of water on the runway surface.

Circumstances:
Following a wrong approach configuration, the airplane landed 848 meters past the runway 26 threshold. Unable to stop within the remaining distance, the airplane overran, lost its undercarriage and came to rest in flames few dozen meters further. All 58 occupants were able to evacuate the cabin and five of them were injured. The aircraft was damaged beyond repair.
Probable cause:
Wrong approach configuration on part of the flight crew who continued the descent while the aircraft was too high on the glide and unstable with an excessive approach speed. This caused the airplane to land too far down (848 meters past the threshold) a wet runway contaminated by heavy rain falls. In such conditions, the airplane was unable to stop within the remaining distance and overran at a speed of 80 knots. Because the aircraft was unstable and the approach configuration was wrong, the crew should initiate a go-around maneuver.

Circumstances:
During the takeoff roll at Rio de Janeiro-Santos Dumont Airport, about 8 knots below V1 speed, the captain noticed a loss of power on both engines while the turbine temperature was at its maximum. In such situation, the captain decided to abort the takeoff procedure and applied brakes. It appears the aircraft failed to decelerate properly so the crew activated the emergency brakes that were effectives on the right main gear only. As the end of the runway was approaching, the captain retracted the undercarriage so the airplane sank on its belly and slid before coming to rest into the Guanabara Bay. The aircraft sank about 10 minutes later and was lost. Eight passengers were killed while 57 other occupants were injured, some of them seriously.
