What went wrong with Boeing 737 max 8

Travelling by air to many is the perfect journey, and when you can carry a lot of people at the same time ,that's gold

That's just what Boeing gave to us.

The Boeing 737 MAX is a narrow-body aircraft series designed and produced by Boeing Commercial Airplanes as the fourth generation of the Boeing 737, succeeding the Boeing 737 Next Generation (NG).

The 737 MAX series has been offered in four variants, typically offering 138 to 230 seats and a 3,215 to 3,825 nmi (5,954 to 7,084 km) range. The 737 MAX 7, MAX 8, and MAX 9 are intended to replace the 737-700, -800, and -900, respectively. Additional length is offered with the further stretched 737 MAX 10. As of January 2019, the Boeing 737 MAX has received 5,011 firm orders and delivered 350 aircraft.

Then the big bird started to fall ,After two fatal crashes of MAX 8 aircraft in October 2018 and March 2019, regulatory authorities around the world grounded the aircraft series indefinitely. On March 19, 2019, the U.S.

Department of Transportation requested an audit of the regulatory process that led to the aircraft's certification in 2017.

And since the falls aviation experts have been giving reasons for the fall.

(1) THE PILOTS DIDN'T TRAIN WELL FOR IT

Normally when a new product enters the aviation market, pilots are trained to adapt to the new product but in the case of the ill - fated plane the pilot assumed it is same with the earlier Boeings ,and this they said didn't allow much romance between them.

And

(2) THE USE OF THE MANEUVERING CHARACTERISTICS AUGMENTATION SYSTEM (MCAS)

The Maneuvering Characteristics Augmentation System (MCAS) was developed for the 737 MAX to prevent stalls in flaps-retracted, low-speed, nose-up flight. Maneuvering Characteristics Augmentation System (MCAS)

The Maneuvering Characteristics Augmentation System (MCAS) was developed for the 737 MAX to prevent stalls in flaps-retracted, low-speed, nose-up flight. The MCAS uses airspeed, altitude and angle of attack (AOA) sensor data to make an attempt at computing when a dangerous condition has developed and then trims the aircraft nose down. this is because the

Boeing 737 MAX aircraft have engines mounted higher and further forward than previous 737 models. This engine relocation and the new nacelle shape cause an upward pitching moment. In order to pass Part 25 certification requirements, Boeing employed the MCAS to automatically apply nose-down trim when the aircraft is in steep turns or in low-speed, flaps-retracted flight. When the angle of attack (AOA) exceeds a limit that depends on airspeed and altitude; the system is temporarily deactivated when a pilot trims the aircraft using a switch on the yoke.

And this same prevention mechanism is leading the possible causes, as the (MCAS) was said to get out of control and then the plane nose dived ,with the pilot trying to return the system to normal but then a tug of war happened between them. And unfortunately the computer won.

And now the Boeing 737 max 8 is now out of market indefinitely. We hope it get back better soon.and then maybe they can gain our trust back
