Debris that washed ashore in Mozambique that may be from missing Malaysia Airlines Flight 370 turned up in a spot that matches investigators' theories about where wreckage from the plane would have ended up, Australian officials said Thursday.

Photos of the debris discovered over the weekend appear to show the fixed leading edge of the right-hand tail section of a Boeing 777, said a U.S. official, who spoke on condition of anonymity because he wasn't authorized to speak publicly. Flight 370, which disappeared two years ago with 239 people aboard, is the only known missing 777.

The plane is believed to have crashed somewhere in a remote stretch of the southern Indian Ocean far off Australia's west coast and about 6,000 kilometers (3,700 miles) to the east of Mozambique. But authorities have long predicted that any debris from the plane that isn't on the ocean floor would eventually be carried by currents to the east coast of Africa.

Australian Transport Minister Darren Chester reiterated that opinion Thursday, saying the location of the debris in Mozambique matches investigators' drift modeling and would therefore confirm that search crews are looking in the right part of the Indian Ocean for the main underwater wreckage.

People who have handled the part, called a horizontal stabilizer, say it appears to be made of fiberglass composite on the outside, with aluminum honeycombing on the inside, the U.S. official said.

The Australian Transport Safety Bureau, which is running the search for the plane in remote waters off Australia's west coast, said the part was expected to be transported to Australia for examination.

Malaysian transport minister Liow Tiong Lai also confirmed in tweets about the discovery that it appears the debris may have come from the missing plane.

"Based on early reports, high possibility debris found in Mozambique belongs to a B777," Liow said in a series of tweets.

"It is yet to be confirmed & verified. @dca_malaysia working w Australian counterparts to retrieve the debris." He urged "everyone to avoid undue speculation as we are not able to conclude that the debris belongs to #mh370 at this time."

Australian officials have seen photographs of the debris and have been in communication with Blaine Gibson, the American man who found the part, said Dan O'Malley, a spokesman for the Australian Transport Safety Bureau.

"We're aware of these reports that debris has been found in Mozambique," O'Malley said. "We're working with officials in Mozambique and Malaysia to investigate."

Australia will work with Malaysian investigators to examine the object once it arrives in Australia, he said. The ATSB hasn't made any determinations yet about the potential origins of the debris.

"We have to wait until we have the actual debris examined," O'Malley said. "We're not going to draw conclusions from the photos."

Some have expressed skepticism that the part could be from the missing aircraft because it appears to be remarkably clean and free of sea life — unlike the barnacle-encrusted wing part that washed ashore on the French island of Reunion last year. That part, known as a flaperon, remains the only confirmed trace of Flight 370.

But Charitha Pattiaratchi, an oceanographer with the University of Western Australia, said if the part was discovered on a sandbank as reported, the motion of the waves pushing it against the abrasive sand may have shaved any sea life off it.

"If somebody actually found it in the middle of the ocean while they were sailing and picked it up, I would say, 'Well, that should have some barnacles,'" he said. "But if it's been on a beach, it's basically been sandblasted."

Also, the part appears to be very flat and barnacles need something to grip, he said.

Last year, Pattiaratchi met with Gibson, a Seattle man who has been combing beaches around the region for debris from the missing plane.

Pattiaratchi has used computer modeling to predict where floating debris from Flight 370 might end up and Gibson wanted to get Pattiaratchi's opinion on where to look. Pattiaratchi's models showed it would likely end up around Madagascar or Reunion Island, and possibly in the Mozambique Channel. And that's apparently where Gibson went, Pattiaratchi said.

Flight 370 disappeared on March 8, 2014, while flying from Kuala Lumpur to Beijing. Authorities who scrutinized data exchanged between the plane's engine and a satellite determined that after veering sharply off course, the jetliner continued on a straight path across the Indian Ocean, leading them to believe that it flew on autopilot for hours before running out of fuel and crashing into the water.

Australia has led a multinational search effort, which also includes the Malaysian and Chinese governments. But no trace of the passengers, their luggage or even things designed to float, such as life jackets, has been discovered.

With authorities unable to find the plane and its "black box" flight data and cockpit voice recorders, investigators are no closer than they were two years ago to discovering the cause of the aircraft's disappearance.

With the search tentatively scheduled to wrap up later this year, Flight 370 may become one of aviation's great unsolved mysteries.
