A preliminary assessment of airplane debris found off the coast of Reunion island Wednesday indicates it is "consistent in appearance" to the aircraft used in Malaysia Airlines Flight 370, a source close to the investigation told CNN. 

The debris is currently under investigation to determine whether it is indeed part of the Boeing 777 that disappeared over the Indian Ocean in March 2014. 

The French aviation safety bureau released a statement Wednesday saying that it is "studying the information...in coordination with our Malaysian and Australian colleagues," and that it is "not possible at this hour to ascertain whether the part is from a B-777 and/or from MH370," The New York Times reported. 

Malaysian Airlines flight 370 lost contact with air traffic control less than one hour after takeoff on March 8, 2014. There were 239 people on board the flight, which was bound for Beijing from Kuala Lumpur.
