After staying grounded for almost two years because of two deadly crashes in a span of five months, the Boeing 737 Max aircraft is finally getting back to the skies. After clearances came in from regulators in the United States and Europe, announcing the aircraft safe to fly, at least 18 airlines have started operating commercial flights, according to an IE report.
In the month of October 2018, the newest member of Boeing’s 737 narrow-body family- 737 Max crashed in the Java Sea shortly after takeoff from Jakarta, Indonesia. Then another aircraft of the same model crashed in Ethiopia in March 2019. Both these plane accidents killed 346 people in total.
Following the second plane crash in Ethiopia, global aviation authorities decided to ground the aircraft pending an investigation into the cause behind the plane crashes. During that time, several airlines including large carriers such as United, Southwest, American, Air Canada, Indian carrier SpiceJet, were operating the 737 Max aircraft in their fleets. During the investigation of the crashes, it was found that the main cause of both the plane accidents was a design flaw in the most modern jetliner.
The latest model of Boeing 737 is installed with manoeuvring characteristics augmentation system. The MCAS is responsible for pushing the nose of the aircraft down when it senses a high angle of attack that may result in an aircraft stall. If the nose of a plane is too high, the aircraft loses speed and it is likely to enter a stall- a state in which it loses flight and from the sky, it can fall like a stone
