Brazilian search crews say they have found bodies and debris from Air France Flight 447, which crashed into the Atlantic Ocean Monday.

Brazilian Air Force Colonel Jorge Amaral told reporters of  the discovery Saturday, but offered few details.

French investigators said Saturday that Airbus, the makers of the downed plane, had discovered faulty airspeed readings in its A330 jets and had recommended the replacement of a sensor in the planes. Air France had not acted on the recommendation.  

The head of the French agency leading the probe into the crash, Paul-Louis Arslanian, said he cannot say if the sensor played any role in the crash of the plane.

Airbus issued the advisory after air safety investigators said equipment that sent out automatic signals from the downed jet showed inconsistencies in its speed.

Arslanian says investigators are analyzing 24 error messages sent automatically in the final moments of the flight.

French submarines are expected to arrive off the Brazilian coast next week to assist in the search for flight wreckage.  The Airbus 330 was flying from Rio de Janeiro to Paris when it went down.

Investigators are hoping to find the plane's flight data and cockpit voice recorders ("black boxes"), which are designed to send out signals for 30 days after an accident.  

The recorders would have information from the final minutes of the flight.  The recorders are believed to be sitting on the ocean floor at depths of at least 3,000 meters.

Brazilian officials reported earlier this week that military pilots had spotted wreckage from the airliner, but pieces pulled from the water turned out to be unrelated to the plane.  Flight 447 had 228 people on board. 

Some information for this report was provided by AFP, AP and Reuters.
