The aircraft debris found in Mauritius last May has been confirmed to be from missing Malaysia Airlines flight MH370.

Transport Minister Datuk Seri Liow Tiong Lai said the examination of the composite debris recovered on the Indian Ocean island has been completed by experts from the Australian Transport Safety Bureau (ATSB).

"With the concurrence of the MH370 Safety Investigation Team, ATSB's analysis of the piece has determined the following:

• From a part number found on a section of the debris, the piece has been identified as a trailing edge splice strap, incorporated into the rear spar assembly of a Boeing 777 left outboard flap.
• This is also consistent with the appearance and construction of the debris.
• Adjacent to the part number was a second part identifier.
• The flap manufacturer supplied records indicating that this work order number was incorporated into the outboard flap shipset line number 404.
• This corresponds to the Boeing 777 aircraft line number 404, registered as 9M-MRO (MH370).

"As such, the experts have concluded that the debris piece originated from the aircraft 9M-MRO, also known as MH370," he said in a statement.

He also expressed appreciation to the Mauritian and Australian authorities for their support and assistance, adding that updates in the matter would be made accordingly.

Last month, it was confirmed that the debris found in the island of Pemba off Tanzania in June was confirmed to be from MH370.

MH370 went missing on March 8, 2014, during a routine flight from the Kuala Lumpur International Airport to Beijing, China, with 239 passengers and crew on board.
