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 October 31, 1996, which crashed shortly after take-off, killing a total of 99 people.
During climbing, the No. 2 engine suffered an uncommanded reverse thrust deployment. The aircraft yawed to the right, striking a building and crashing in a populated area, killing all 96 people aboard as well 3 on the ground.
The aircraft, PT-MRK, wore a TAM Transportes Aéreos Regionais special promotion livery - "Number 1" at that time instead of the standard TAM livery.
