TAM Transportes Aéreos Regionais Flight 402 was a scheduled domestic flight from Congonhas-São Paulo International Airport in São Paulo, Brazil to Santos Dumont Airport in Rio de Janeiro. On 31 October 1996, at 8:27 am, the Fokker 100 operating the route suffered uncommanded reverse thrust deployments on its starboard engine while climbing from Congonhas, making the aircraft stall, roll beyond control to the right, strike two buildings and crash into several houses in a heavily populated area only 24 seconds after takeoff, killing all 96 people aboard as well as three on the ground. It is the fourth deadliest accident in Brazilian aviation history, the second at the time.
