Australian investigators believe the plane ran out of fuel.
The agency in charge of the search for the missing plane said the presence of the simulator data did not prove the pilot intentionally crashed the jet.
The plane, with 239 aboard, disappeared in March 2014.
So far, nothing has been found.
Australia will test the piece as part of the investigation into the missing Malaysia Airlines flight.
The flaperon piece was found off the coast of the Indian Ocean in July.
