A new computer problem has been found in the troubled Boeing 737 Max that will further delay the plane's return to flying after two deadly crashes, according to two people familiar with the matter.
The loss of Ethiopian flight ET302 in March was the second fatal accident involving a 737 Max in the space of five months. Investigators allege that this system malfunction was the reason behind fatal crashes of the Lion Air and Ethiopian Airlines in October and March, respectively, killing almost 350 people in total. The FAA said Wednesday it has found a new flaw in the plane that needs to be fixed.
Boeing says in a statement that the company is working on the required software fix to address the FAA's request.
In a statement, the Federal Aviation Administration said it will lift its grounding of the plane only when it deems the jet safe - there is no set timeline.
In a tweet, the FAA said: "On the most recent issue, the FAA's process is created to discover and highlight potential risks". During one activation it took an extended period to recover the stabilizer trim system that is used to control the aircraft, the people said.

It was not clear if the situation that resulted in an uncommanded dive can be addressed with a software update or if it is a microprocessor issue that will require a hardware replacement.
Aerial shots and footage from the company's Renton factory in Washington state, shows a number of aircraft parked in the parking lot meant for cars and has got everyone talking online.
A hardware fix could add new delays to the plane's return to service.
"We also are responding to recommendations received from the Technical Advisory Board", it said.
Per a Bloomberg tally, Boeing is storing 500 grounded 737 Max jets at various locations around the world, including around 100 at its Renton factory.
