Workers unload debris from crashed AF447 in the port of Recife, Brazil, 14 Jun 2009Brazil has called off its search for more bodies and debris from theAir France flight that plunged into the Atlantic Ocean four weeks ago.

BrazilAir Force Lieutenant Colonel Henry Munhoz said Friday that it was notlikely any more bodies or wreckage from the crash would be found. Search teams have recovered 51 bodies and hundreds of pieces ofdebris.   

Flight 447, en route to Paris from Rio de Janeirowith 228 people aboard, disappeared from radar over the Atlantic Oceanlate on May 31.  

Authorities say the search for the plane'svoice and flight data recorders will continue. The recorders would helpinvestigators piece together the final minutes of the doomed flightthat went down during a storm.   

Last week,  Air France announced it will pay an advance of about $24,000 to the families of each victim of the crash.

AirFrance CEO Pierre-Henri Gourgeon said the company's lawyers are intouch with the families to put the payments in process.  He did notsuggest that the compensation means an admission of guilt on the partof the airline.

The CEO also said a memorial service for the 228 victims is being planned.

Theinvestigation has focused on the possibility that icing on the externalspeed sensors caused incorrect airspeed readings in the cockpit, whichcould have led the crew to fly dangerously fast or slow.

Air France has since replaced the sensors on its entire fleet of long-haul A330 and A340 planes.
