An Air France plane missing over the Atlantic with 228 people aboard reported electrical problems before it lost contact, the airline said Monday.
The Airbus A330-200 jet had experienced turbulence during the 11-hour flight from Rio de Janeiro to Charles de Gaulle airport in Paris, the spokesman said.
Brazil's air force has launched a search near the archipelago of Fernando de Noronha in the Atlantic Ocean, 365 km (226 miles) from Brazil's coast, a spokesman for the air force told CNN.
Two Brazilian squadrons are searching for the plane, although it disappeared after it left the country's radar space, said the officer, who declined to be named.
The flight, AF 447, took off shortly after 7 p.m. Sunday local time (6 p.m. Sunday ET) for the 11-hour flight, with 216 passengers and 12 crew members. It was scheduled to land in Paris at 11:15 a.m. local time (5:15 a.m. ET).
The last known contact with the plane was at 1 a.m. GMT (8 p.m. Sunday night ET), the Brazilian Air Force spokesman said.
Air France said it could not confirm reports of a short circuit on board the aircraft.
The airline said it "shared the emotion and the concern of the families concerned" adding that friends and relatives waiting at the airport would be taken to a special area.
A crisis center is being set up at Charles de Gaulle where the plane had been due to land at 11.15 a.m. local time.
Agence France-Presse quoted France's Environment Minister Jean Louis Borloo saying that it was extremely unlikely the plane had been hijacked.
"We are very worried," an aviation official told AFP. "The plane disappeared from the screens several hours ago. It could be a transponder problem, but this kind of fault is very rare and the plane did not land when expected."
The Airbus 330 is a twin-engine long-range aircraft introduced into commercial aviation in the 1990s.
Transport analyst Kieran Daly told CNN that the lack of communication with the aircraft "does suggest it was something serious and catastrophic."
He said the aircraft involved is believed to be one delivered to Air France in April 2005.
"It is an extremely young fleet by aviation standards," he said. "The A330 is state of the art with extremely reliable engines made by General Electric."
CNN air travel expert Richard Quest says the plane, a stalwart of trans-Atlantic routes, has an impeccable safety record.
"It has very good range, and is extremely popular with airlines because of its versatility," he said.
