The Federal Aviation Administration reportedly has launched a review of the safety analyses that Boeing Co. (BA - Get Report) has performed over the years regarding potential hazards associated with a new automated flight-control system introduced on the latest versions of the 737 Max aircraft, The Wall Street Journal reported.

The FAA, however, said in a statement that it wasn't conducting a separate or new investigation. 

"The existing FAA Airworthiness Directive (AD) identifies existing flight crew procedures to be used in those circumstances," the FAA statement said. "The FAA and Boeing continue to evaluate the need for software and/or other design changes to the aircraft including operating procedures and training as we learn more from the ongoing investigation."

The Journal previously reported that Boeing withheld information about potential hazards connected with the new flight-control feature that is suspected of playing a role in last month's fatal Lion Air jet crash in Indonesia. The Lion Air jet crashed into the Java Sea after taking off from Jakarta, killing all 189 on board.

The system is designed to pull the plane out of a dangerous stall.

Boeing hasn't responded to a request for comment.

Shares of Boeing were up slightly in premarket trading.
