Brazilian authorities are working to piece together what exactly caused a plane with 62 people aboard to crash in a fiery wreck in Sao Paulo state on Friday.

Local airline Voepass’ plane, an ATR 72 twin-engine turboprop, was headed for Sao Paulo’s international airport in Guarulhos with 58 passengers and 4 crew members when it went down inside a gated community in the city of Vinhedo. The plane took off from Cascavel Airport at 11:46 a.m. local time, the airline said.
