The debris is said to be most likely from a Boeing 777, like the MH370 that vanished two years ago.
It was found on a sandbank in the Mozambique Channel — the body of water between Mozambique in eastern Africa and Madagascar — and in the same corner of the southern Indian Ocean where the only confirmed piece of debris, a flaperon, was found last July, the report said.
NBC said investigators in Malaysia, Australia and the U.S. had looked at photographs of the latest object and the sources said there was a good chance it came from a Boeing 777.
Boeing engineers were looking at the photos, according to sources, but the company declined to comment.
The object has the words “NO STEP” on it and could be from the plane’s horizontal stabiliser — the wing-like parts attached to the tail, the sources said.
It was discovered by an American who had been blogging about the search for MH370.
The jet disappeared en route from Kuala Lumpur to Beijing on March 8, 2014 with 239 people on board.
No trace has been found of Flight MH370 except for the single barnacle-encrusted flaperon that washed up on the eastern shore of Reunion, east of Madagascar, last July.
The search for the missing plane is now ongoing in the southern Indian Ocean.
