The information has not been confirmed by authorities. Investigators have previously stated that feathers were found in one of the plane's two engines.
179 people died when the plane from Jeju Air crashed into a wall at the airport in Muan at the end of December. Only two people survived.
The cause of the accident has not been established, but investigators have previously pointed to a possible bird collision.
About four minutes before the crash, one of the pilots reported that the plane had collided with birds, according to South Korean authorities. Shortly beforehand, air traffic controllers on the ground had reported "bird activity" in the area.
