Ethiopian Airlines preliminary crash report shows similarities to Lion Air disaster

Source: CNN

The pilots on board Ethiopian Airlines flight 302 battled the plane's automated flight control systems for almost the entire duration of the six-minute flight, according to a preliminary report into the crash obtained by CNN on Thursday.

The captain and the first officer struggled as the 737 Max 8's systems, designed to prevent the plane stalling, repeatedly forced the nose of the plane down. For nearly six minutes, the report shows, the pilots worked through a series of procedures to try and regain control of the plane.

In the end, after the pilots had turned back, the automated system pitched the plane into a steep dive from which it was impossible to recover, and it crashed into the ground.

The problems on board the Ethiopian Airlines flight mirror those encountered on the doomed Lion Air flight 610 -- which operated the same 737 Max 8 model and crashed in October -- in what could be a significant blow to Boeing as it struggles to get the aircraft back in service.

They run those new aircraft through all kinds of tests....Drag the rear end
on the runway during takeoff...All kinds of stall tests...High gravity turns,
Altitude checks...

Its just unimaginable to me they would have missed something like
this....stall system that can't be turned off...or is turned off but
comes back on...Somethings fishy...

for Profit's. This new Software on the Max was to sell planes without training Pilots and thus saving everyone millions in labor costs.

All about profits first and payoffs second.

jumped to stressing safety of this plane and minimizing similarity of crashes when this first occurred and how U.S. dragged it’s heels before grounding these, doing so only after most other countries had done so.

Now they are making all the proper statements about every effort to fix this, etc., but if they had had their way, these would still be flying and onus of blame on pilots rather than systemic issues.

We at Boeing are sorry for the lives lost in the recent 737 MAX accidents. These tragedies continue to weigh heavily on our hearts and minds, and we extend our sympathies to the loved ones of the passengers and crew on board Lion Air Flight 610 and Ethiopian Airlines Flight 302. All of us feel the immense gravity of these events across our company and recognize the devastation of the families and friends of the loved ones who perished.

The full details of what happened in the two accidents will be issued by the government authorities in the final reports, but, with the release of the preliminary report of the Ethiopian Airlines Flight 302 accident investigation, it’s apparent that in both flights the Maneuvering Characteristics Augmentation System, known as MCAS, activated in response to erroneous angle of attack information.

The history of our industry shows most accidents are caused by a chain of events. This again is the case here, and we know we can break one of those chain links in these two accidents. As pilots have told us, erroneous activation of the MCAS function can add to what is already a high workload environment. It’s our responsibility to eliminate this risk. We own it and we know how to do it.

From the days immediately following the Lion Air accident, we’ve had teams of our top engineers and technical experts working tirelessly in collaboration with the Federal Aviation Administration and our customers to finalize and implement a software update that will ensure accidents like that of Lion Air Flight 610 and Ethiopian Airlines Flight 302 never happen again.

We’re taking a comprehensive, disciplined approach, and taking the time, to get the software update right. We’re nearing completion and anticipate its certification and implementation on the 737 MAX fleet worldwide in the weeks ahead. We regret the impact the grounding has had on our airline customers and their passengers.

This update, along with the associated training and additional educational materials that pilots want in the wake of these accidents, will eliminate the possibility of unintended MCAS activation and prevent an MCAS-related accident from ever happening again.

We at Boeing take the responsibility to build and deliver airplanes to our airline customers and to the flying public that are safe to fly, and can be safely flown by every single one of the professional and dedicated pilots all around the world. This is what we do at Boeing.

We remain confident in the fundamental safety of the 737 MAX. All who fly on it—the passengers, flight attendants and pilots, including our own families and friends—deserve our best. When the MAX returns to the skies with the software changes to the MCAS function, it will be among the safest airplanes ever to fly.

We’ve always been relentlessly focused on safety and always will be. It’s at the very core of who we are at Boeing. And we know we can always be better. Our team is determined to keep improving on safety in partnership with the global aerospace industry and broader community. It’s this shared sense of responsibility for the safety of flight that spans and binds us all together.

I cannot remember a more heart-wrenching time in my career with this great company. When I started at Boeing more than three decades ago, our amazing people inspired me. I see how they dedicate their lives and extraordinary talents to connect, protect, explore and inspire the world — safely. And that purpose and mission has only grown stronger over the years.

We know lives depend on the work we do and that demands the utmost integrity and excellence in how we do it. With a deep sense of duty, we embrace the responsibility of designing, building and supporting the safest airplanes in the skies. We know every person who steps aboard one of our airplanes places their trust in us.

Together, we’ll do everything possible to earn and re-earn that trust and confidence from our customers and the flying public in the weeks and months ahead.

Again, we’re deeply saddened by and are sorry for the pain these accidents have caused worldwide. Everyone affected has our deepest sympathies.
