The Brazilian aviation regulator Agência Nacional de Aviação Civil (ANAC) decided on March 14, 2013 to suspend the Air Operator Certificate of Fretax Táxi Aéreo following a fatal accident.
On March 12, 2013 an Embraer EMB-820C Carajá passenger plane of Fretax crashed near Monte Dourado Airport, Brazil, killing the pilot and all nine passengers. The EMB-820C Carajá is a turboprop conversion of a license built Piper PA-31 Navajo with two Pratt & Whitney Canada PT6A-27 engines. It was apparently flown on an IFR flight plan from Belém with just one pilot on board. According to regulations the airplane had to be flown IFR by a two-man crew.
Fretax Táxi Aéreo is an airline established in 2002, operating a mixed fleet of Cessna 208 Caravan, EMB-820C, and Beechcraft 58 Baron aircraft used for passenger and cargo flights.
