(Sept 1): A Spanish company which manufactures wing parts for Boeing 777 said it could not confirm that the debris found on the French island of Reunion last July was that of missing Malaysian Airlines flight MH370, CNN reports.

This comes three weeks after Prime Minister Datuk Seri Najib Razak announced that the debris, in the form of a 2-metre long aircraft part called a flaperon, was confirmed to be that of the missing plane which vanished without a trace on March 8 last year.

But CNN reported that the company told French investigators "that it cannot tell with certainty from consulting its records whether the flaperon found on Reunion Island came from MH370".

It said attempts by investigators to match a number found on the debris with records from the company "proved impossible".

The Malaysian government appeared to be the only one to confirm with absolute certainty that the flaperon belonged to MH370.

French investigators meanwhile told CNN last week that although the flaperon, which experts believed was that of a Boeing 777, is likely to be from the missing plane, it cannot confirm the link.

"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," Martine Del Bono from French aviation body Bureau d'Enquêtes et d'Analyses (BEA) told CNN.

Flight MH370 with 239 people left Kuala Lumpur for Beijing on March 8 but went missing after an hour.

Australia has been leading an expensive multinational effort to find the plane in the southern Indian Ocean, but no wreckage of the plane was spotted until the discovery of the flaperon which raised hopes of solving the mystery of the missing flight. – The Malaysian Insider
