PARIS, July 2 (Reuters) - Authorities have no data that would indicate any need to ground Airbus A-330 aircraft following the crash of an Air France plane in the Atlantic last month, a French crash investigator said on Thursday.

The Air France flight AF 447 went missing during a flight from Rio de Janeiro to Paris on June 1. The exact causes of the disaster are not yet known. (Reporting by Tim Hepher, editing by James Mackenzie)
