Boeing 737 Max: New flaw could delay return of aircraft

ANKARA

U.S. regulators have found a new potential risk in Boeing 737 Max aircraft during simulator tests.

The Federal Aviation Administration (FAA) said Wednesday in a statement it is monitoring the situation.

"The FAA will lift the aircraft’s prohibition order when we deem it is safe to do so," it added.

Boeing's top-selling aircraft model was grounded worldwide after two crashes that cost hundreds of lives.

On March 10, Ethiopian Airlines flight ET-302, which used the Boeing 737 MAX, crashed shortly after taking off from Addis Ababa airport, killing all 157 on board.

The plane model was also involved in an October crash outside of Jakarta, Indonesia. All 189 people on board Lion Air flight JT610 were killed.

Many countries, including the U.S., Turkey, Russia and Iran, began to order the grounding of the plane model in their airspace.

Boeing which has remained confident about the safety of the aircraft had said a software fix would solve the problem.
