Can't Say With Certainty That Flaperon Is From MH370

French authorities are not ready to say with certainty whether the flaperon that washed up on Reunion Island in late July is a part of a missing Malaysian airliner, according to sources close to the investigation.

CNN reports that authorities are sure it is from a Boeing 777. But they have not identified a number inside the part, according to the report.

The French are inspecting the debris because Reunion Island is a French territory. The part was discovered there on July 29.

Malaysian authorities have said with certainty that the part is from the Malaysian Airlines 777, which went missing March 8, 2014. No other possible debris from the plane has been found.

"Experts still haven't determined the causes of the MH370 accident," said Martine Del Bono, spokesperson for the French accident investigation agency BEA (Bureau d'Enquêtes et d'Analyses).

"The flaperon isn't enough. We need more. We need to localize the wreckage. It is extremely crucial in order to determine what happened."

"BEA investigators helped with the searches on Reunion Island and Maldives but we couldn't find any more debris so we stopped the searches.

"There are strong indications that this flaperon is from MH370, but we are still unsure. We are still missing identification from the parts list in order to fully confirm it is from MH370."
