Air France boss denies faulty sensors to blame for crash

AIR FRANCE received replacement airspeed sensors for its Airbus 330s three days before the fatal crash of Flight 447, but the airline’s chief executive said that he is not convinced faulty monitors were the cause.

As storms bore down on the crash zone off Brazil, a French submarine searched the depths of the Atlantic Ocean for the black boxes that hold the best hope of finding out what did happen to the plane when it flew into heavy storms on May 31 with 228 people aboard.

So far, investigators have focused on the possibility that external speed monitors — Pitot tubes — iced over and gave false readings to the plane’s computers.
