Airbus Reassurances

Airbus denied a French newspaper report that it was considering grounding its fleet of A330 and A340 planes following the disaster, saying they were safe to fly.

Gourgeon said the planemaker had reassured clients that all three types of speed sensors available for its jets were safe, including the one used on the crashed A330.

Industry sources said the planemaker had also ruled out for the time being that there was an electrical power failure or loss of cockpit instrument display on the Air France jet.

Air France said at the weekend it had noticed the icing problems on the speed sensors in May 2008, although Gourgeon said these "incidents" had not been deemed catastrophic.

The speed sensors on the Air France A330 were supplied by France's Thales, which has produced two versions of the pitot tube for the Airbus aircraft. A third model made by US firm Goodrich have not been called into question.

The crashed plane had an earlier Thales model, which is being replaced by a more recent probe.

Brazilian and French search teams are searching for bodies and plane debris in the Atlantic some 1,000 km (620 miles) from Brazil's northern coast. A nuclear-powered French submarine is leading the search for the plane's flight recorders.

Gourgeon said more information about the crash would be available once autopsies had revealed the exact cause of death and after experts had scrutinised the debris.

"I think we will have a little bit more information in a week," he said.
