PARIS: Air France is not yet convinced that faulty speed sensors were to blame for the loss of one of its planes over the Atlantic, but it is replacing old sensors as a precaution, the airline's chief executive said yesterday.

Pierre-Henri Gourgeon told reporters that Air France was in a state of shock over the worst disaster in its 75-year history and expected more information about what happened within a week.

An Air France Airbus 330 crashed into the sea on June 1 enroute from Brazil to Paris, killing all 228 aboard.
