BRASILIA (AFP) - Search aircraft on Tuesday found a seat and other debris from a plane in a remote stretch of the Atlantic where an Air France flight carrying 228 people disappeared, Brazils air force said. The small remains were discovered around 1,100 kilometers off northeastern Brazil, some 650 kilometers northeast of Brazils Atlantic island archipelago of Fernando de Noronha. The items include a seat from a plane, bits of white material, an orange buoy, a barrel and some oil and kerosene slicks, grouped in two floating patches 60 kilometers apart, according to an air force statement. It could not immediately be confirmed that the debris was from Air France flight AF 447, the spokesman, Colonel Jorge Amaral, told reporters. There were no signs of survivors, he said. The search is continuing because its very little material in relation to the size of the Air France Airbus A330, he said. He added that officials needed a piece that might have a serial number, some sort of identification to be sure that it came from the missing airliner. However, the items were found near where the Air France plane sent its final message: an automatic data signal telling of multiple electric and pressurization failures. Amaral told AFP the location of the debris suggested the Air France pilot had tried to turn to the right. There could have been a problem and he might have been trying to return to Fernando de Noronha. The Fernando de Noronha archipelago, part of a marine national park that is popular with well-heeled tourists, has an airport. The islands lie 370 kilometers (222 miles) offshore from the Brazilian mainland. Air France flight AF 447 disappeared in the mid-Atlantic on Monday, four hours into an 11-hour flight from Rio de Janeiro to Paris. A Brazilian air force statement said the debris was discovered at 0300 GMT Tuesday by an Embraer R-99 plane fitted with onboard radar and multi-spectral scanner that detected metallic and non-metallic items floating in the ocean. After homing in the search to that locale, other air force planes at 0949 GMT spotted the patches of floating debris. Brazilian navy vessels were headed to the debris zone. Three cargo ships nearby-two Dutch-flagged and one French-had also been asked to deviate to inspect the area and should arrive in the next few hours, a Brazilian navy official, Lieutenant Henrique Afonso Lima, said.
