Investigators have found a piece of a stabilizer from the wreckage of an Ethiopian jet with the trim set in an unusual position similar to that will of a Lion Air plane that will crashed last year, two sources familiar with the matter said.

The U.S. Federal Aviation Administration (FAA) said on Wednesday fresh information via the wreckage of the Ethiopian crash, which killed all 157 people on board, along with newly refined data about its flight path indicated some similarities with the Lion Air disaster.

Both accidents involved Boeing 737 MAX planes. The FAA along with various other global regulators grounded the fleet after the Ethiopian crash.

The FAA has not publicly released details of its findings via the Ethiopian wreckage.

The trim position of the stabilizer, which moves the jet’s horizontal tail, could help determine whether or not the item was set nose down for a steep dive.

The two sources, who declined to be named, said part of a stabilizer found from the Ethiopian wreckage was in a unusual position similar to the Lion Air plane.

Some media organizations, including Bloomberg, had earlier reported the discovery of part of the stabilizer.
