Category: Accident
A VASP YS-11 aircraft overran into Guanabara Bay during takeoff from Rio de Janeiro-Santos Dumont Airport, Brazil, resulting in the loss of 8 occupants and 57 survivors. A temporary loss of power, followed by a rapid increase in TGT, led to braking failure and activation of emergency brakes, ultimately resulting in the aircraft sliding into the bay.A VASP YS-11 aircraft overran into Guanabara Bay during takeoff from Rio de Janeiro-Santos Dumont Airport, Brazil, resulting in the loss of 8 occupants and 57 survivors.

Description
VASP flight 012, a NAMC YS-11, overran into Guanabara Bay during takeoff from Rio de Janeiro-Santos Dumont Airport, Brazil, killing 8 occupants; 57 survived the accident. A temporary loss of power occurred 8 knots before the V1 speed, followed by an increase of the TGT (Turbine Gas Temperature) to the maximum. The takeoff was aborted immediately. Because braking action seemed poor, the emergency brakes were activated. Brakes were only effective on the right main gear, so the pilot ultimately retracted the gear when it seemed an overrun was imminent. The YS-11 continued and slid into Guanabara Bay.
