As the investigation continues, both recorders of the flight were recovered. However, investigators could not find any possible cause from the recorders as the flight data recorder showed that the plane was working properly before it broke up. The cockpit voice recorder also showed nothing unusual. The recorder started ten minutes before the flight. After a last sentence said by captain Yi Ching-Fung, "two thousand" at 3.26pm, the recorder captured nothing more spoken. Then, the sound of the plane breaking up was heard at about 3.29pm.
