TAM Airlines Flight 3054 (JJ3054/TAM3054) was a regularly scheduled domestic passenger flight operated by TAM Airlines from Porto Alegre to São Paulo, Brazil. On the evening of July 17, 2007, the Airbus A320-233 serving the flight overran runway 35L at São Paulo during moderate rain and crashed into a nearby TAM Express warehouse adjacent to a Shell gas station.
