Boeing reveals further software problem in 737 MAX airplane

Family Of American Woman Killed In Ethiopian 737 Max Crash Sues Boeing

First preliminary report of Ethiopian Airlines flight ET302 released

Thursday's preliminary report found that both pilots performed all the procedures recommended by Boeing on the March 10 flight but still could not control the jet.

Boeing has admitted that new software added to the Boeing 737 MAX was a factor in the crashes of both Ethiopian Airlines Flight 302 and Lion Air Flight 610.

The anti-stall system, called MCAS, automatically lowers the plane's nose under some circumstances to prevent an aerodynamic stall.

U.S. planemaker Boeing admitted on Thursday that its 737 MAX passenger jet has another software error in addition to the one implicated in two major crashes in recent months. "It's our responsibility to eliminate this risk - we own it, and we know how to do it".

"Don't you think if Boeing knew what the fix was, we would have the fix by now?" he said.

According to the report, readings from the plane's flight data recorder shows that faulty readings from a malfunctioning angle-of-attack (AOA) sensor triggered the Boeing 737 Max's Maneuvering Characteristic Augmentation System (MCAS), which is created to automatically push the nose of the plane downward. The Lion Air flight crashed last November when a faulty sensor on the plane's fuselage triggered the MCAS, sending the plane into an irreversible descent into the Java Sea, killing 189 people.

Samya Stumo, 24, was killed in the Ethiopian Airlines crash last month.

But the full picture of what happened in the cockpit of Flight 302 on March 10 and a newly released data plot have showed how crew and technology interacted in haste which led to control damage and possible crash.

The aircraft manufacturer has said it will introduce a software update for the MCAS in a bid to resolve the sensor problems.

"If the airlines are unhappy with the 737 Max [8] they might not jump on the bandwagon to buy this new Boeing aircraft", Diehl told host John Kiriakou.

"We're adjusting the 737 production system temporarily to accommodate the pause in MAX deliveries, allowing us to prioritize additional resources to focus on software certification and returning the MAX to flight", Muilenberg said.

"We're taking a comprehensive, disciplined approach, and taking the time, to get the software update right". Aviation authorities should verify that the issues have been adequately addressed "before the release of the aircraft to operations", she said.

The lawsuit alleges, among other things, that "Blinded by its greed, Boeing haphazardly rushed the 737 Max 8 to market, with the knowledge and tacit approval of the United States Federal Aviation Administration ... while Boeing actively concealed the nature of the automated (flight control) system defects".

Some took issue with Ethiopia's transport minister, saying the Ethiopian Airlines pilots had actually failed to properly follow the procedures.

Officials said a full report would be completed within a year of the crash.

About four minutes into the flight, the pilots gave up on the manual stabilizer wheel and switched the electric power to the tail back on, then used the thumb switches on the control column to pitch the nose back up.

Even though pilots took at least some of the steps recommended by Boeing and the FAA to counteract MCAS, they were confused and ultimately lost control, according to the report. He flew 207 of those hours on 737s, including 56 hours on Max jets.
