Deadliest Plane Crash: Boeing 737 Max

The pilots were experienced and the plane was new, but Misfortunes that started with a software error It would lead to a chain of errors leading to an unfortunate end.

At the end of the 11th minute of the journey, which started as a short and ordinary flight, How it turned into a disaster that took 189 lives Let’s explain…

The plane of one of the most well-known airlines was going to take off for a short flight.

Lion Air, one of Indonesia’s relatively affordable airline companies, is one of the most popular airlines in Indonesia. most preferred It was one of the companies. Accustomed to making short, domestic flights every day, the Lion Air Boeing 737 Max aircraft was set to take off on October 28, 2018, to arrive at Bankga Island in Indonesia on a 1.5-hour domestic flight. The plane was also relatively new, having only flown 900 hours.

captain of the plane, Has 6000 hours of flight experience It was 31-year-old Bhavye Suneja. The co-pilot was 41-year-old Harvino, who had 5200 hours of flight experience. Almost half of the plane, which accommodated 189 people, including 9 flight crew, had officers such as prosecutors and police.

There were discrepancies in the instrument panel of the pilot and co-pilot.

The co-pilot was communicating the knot (the main speed used in the aircraft’s performance and aerodynamic calculations) level to the captain pilot. The knot level that the captain and co-pilot see on their screens, from different sources sent, they had to check each other’s screen.

When the co-pilot informed the captain that the speedometer had reached 80 knots, the captain’s indicator read 78. Since there was only a difference of 2 units, no abnormalities were noticed at first. Then, when the plane took off, the system that gave a vibration warning to the pilot was activated and at 1000 feet per minute They were rising.

No one except the pilots noticed that there was a problem. In addition to the widening difference in air speed indicators, there were also large differences in altitude levels. Aeroplane, nose down was going and the captain couldn’t lift his nose.

The system on the plane would have caused the accident.

The reason why the plane went nose down on its own was the system it already had, called MCAS. Due to MCAS, the aircraft cannot hold in the air at low speeds and high nose angle. automatically The nose would go down to the appropriate angle.

In this case, the system continued to go downhill because it was constantly receiving commands from the captain’s faulty screen. In fact, MCAS was activated at least 10 times.

The plane, which took off just 11 minutes ago, crashed into the Java Sea.

Unfortunately, the plane went nose down and crashed into the sea. There were no survivors on the plane, including the crew… From 35 meters below the water The only thing left intact on the recovered plane was the black boxes, and it was immediately clear that the problem was MCAS.

This accident is history It has been engraved as one of the deadliest accidents. Boeing company admitted its mistake and the use of Boeing 737 Max aircraft was temporarily banned.
