I need to find out the arrival to Miami, USA of TAM Flight #8090, from Brasil on July 17 2015.
FlightAware should have this data, but you will need to register (free) to see it.
Unregistered users get to see 14 days of history for free, registered users get 4 months for free. Searches further back in time cost hundreds to thousands of dollars (USD) so don't delay.
Details here from Flightaware. http://uk.flightaware.com/live/flight/TAM8090/history/20150716/0230Z/SBGR/KMIA
