PARIS, France (CNN) -- An Air France plane feared to have crashed in the Atlantic with 228 people aboard reported electrical problems in stormy weather before it lost contact, the airline said Monday, describing the loss as a "catastrophe."
The incident involves an Air France Airbus A330-200.

The Airbus A330-200 sent an automatic message signaling an electric circuit failure as it hit turbulence early in its 11-hour flight from Rio de Janeiro to Charles de Gaulle airport in Paris, Air France CEO Pierre-Henri Gourgeon told a news conference.
The loss of a relatively new model of one of the aviation sector's most reliable and state-of-the-art aircraft has stunned analysts who say it would take extremely violent weather to bring down such a large jet.
Former Airbus pilot John Wiley told CNN that speculation lightning had brought down the plane was likely to prove unfounded since most modern passenger aircraft were capable of withstanding direct strikes.
The last known contact with flight AF 337 -- carrying 126 men, 82 women, seven children and a baby, plus the crew -- was at 1:33 GMT Monday (8:33 p.m. Sunday ET), according to the Brazilian Air Force.
Brazil says it has launched two air force squadrons to hunt near the archipelago of Fernando de Noronha in the Atlantic Ocean, 365 kilometers (226 miles) from its coast, although the plane vanished outside the country's radar coverage.
The Air Force said the jet was last logged flying at an altitude of 10,600 meters (35,000 feet) before contact was lost. When the plane failed to make further contact, Brazilian air controllers contacted their counterparts in Senegal.
France's ambassador to Senegal told CNN affiliate BFMTV that French military aircraft had been dispatched to search the west African country's coast.
French authorities ruled out hijacking. President Nicolas Sarkozy expressed his "very deep concern" and asked the government "to implement every effort to find the plane," according to a statement from his office.
Air France's Gourgeon added: "I can say without doubt that this is a catastrophe." He said: "The entire Air France company and its staff are very moved and affected by this."
Somber members of the families could be seen entering a special terminal set aside for them at Charles de Gaulle airport.
A crisis center was being set up at at the airport to deal with anxious relatives and friends waiting for news of passengers. Air France has also set up a hotline: 0800 800 812 in France, or +33 157021055 for international callers.
Airbus has opened a crisis room and their flight safety team is in place, a company spokesperson told CNN. Airbus is working closely with authorities and Air France, he said, declining to comment further.
Gourgeon said the aircraft involved was a new Airbus piloted by a "particularly experienced crew."
Analyst Kieran Daly of online aviation news service Air Transport Intelligence 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 twin-engine plane, a stalwart of transatlantic routes, has an impeccable safety record.
"It has very good range, and is extremely popular with airlines because of its versatility," he said.
