All 33 people aboard a Brazilian passenger plane were killed when it crashed in the Amazon jungle just minutes from landing at the industrial city of Manaus, aviation authorities said Saturday.

The aircraft, operated by Rico Linhas Aereas, fell into dense jungle Friday evening about nine miles from the Manaus airport in northwest Amazonas state.

The twin-engine turboprop, carrying 30 passengers and three crew members, was on a normal approach in clear skies when it disappeared off the radar screen, Brazil's regional civil aviation service said. It lost contact with air traffic control at about 6:30 p.m.

"There wasn't even time for [the pilot] to speak, it was so fast," Geraldo Gomes Alves, head of the agency in Manaus, said. "He was maybe two minutes from landing."

The airline said all the passengers were Brazilians.

Rescue crews abandoned the search for survivors and wreckage along the banks of the Rio Negro River on Saturday after finding only scattered human remains and unidentifiable fragments of the aircraft.

"They only found small wreckage. No survivors," a spokesman for Rico Linhas Aereas told national radio.

The lack of any large pieces of wreckage indicated the plane exploded, the company spokesman said.

A senior coordinator of the recovery mission, Maj. Raimundo Rodrigues da Silva, said residents reported seeing a ball of flame around the time of the crash.
