Boeing Built Deadly Assumptions Into 737 Max, Blind to a Late Design Change

The fatal flaws with Boeing’s 737 Max can be traced to a breakdown late in the plane’s development, when test pilots, engineers and regulators were left in the dark about a fundamental overhaul to an automated system that would ultimately play a role in two crashes.

A year before the plane was finished, Boeing made the system more aggressive and riskier. While the original version relied on data from at least two types of sensors, the final version used just one, leaving the system without a critical safeguard. In both doomed flights, pilots struggled as a single damaged sensor sent the planes into irrecoverable nose-dives within minutes, killing 346 people and prompting regulators around the world to ground the Max.

But many people involved in building, testing and approving the system, known as MCAS, said they hadn’t fully understood the changes. Current and former employees at Boeing and the Federal Aviation Administration who spoke with The New York Times said they had assumed the system relied on more sensors and would rarely, if ever, activate. Based on those misguided assumptions, many made critical decisions, affecting design, certification and training.

“It doesn’t make any sense,” said a former test pilot who worked on the Max. “I wish I had the full story.”

1. This whole smoke and mirrors

was all about selling Airplanes and Saving Boeing 2.5 Billion Dollars in Pilot Training. Nothing more and nothing less. They had the Certification Process greased at the FAA and could have cared less about things falling apart.

2. Well if selling weapons is more important than human lives

what's the difference with selling defective aircraft.

3. Boeing is truly

getting a pass form our Media. Call it the Andurus - Koch effect. You diss us and we will not buy ads on your Media.

4. This is a very good article

No pass here

5. That was just a rewrite of a

Major Airline Captains honest assessment of what he had learned from just asking other Pilots and People he knew at Boeing.

Found this fellows U Tube detailing his assessment. And as one who trained Air Force Fighter Pilots,he would know the ins and outs of various Plane configurations. Boeing did this on the cheap to keep Airbus from stealing orders. Forgot to mention,Airbus most likely tweaks the truth the same way.

6. I agree

but at least they didn't hide it

[Wellstone ruled]

9. Yup.

7. Boeing made a choice. Ground the planes or cross their fingers and hope no one else dies.

they crossed their fingers and lost....they must pay the price

I haven't had a need to fly since 2001....my kiddos just left for the Philippines...every year after school ends they go to visit for 4-6 weeks with my daughter-in-laws parents in Cebu...my son retired Navy chief 21 years is all over this story....we all need to be vigilant..
