Bad weather in Egypt

This is not the first time that 737MAX has had a plane crash.

2065438+08181On the morning of 29 October, a Boeing 737MAX 8 plane in lion air, Indonesia lost contact about 13 minutes after taking off from Jakarta, and it was confirmed that it crashed near the west coast of Java, Indonesia.

After the crash in Indonesia, the Federal Aviation Administration (FAA) issued an emergency airworthiness directive. On the tenth day after the accident, Boeing issued an announcement to the operators of 737MAX aircraft around the world, warning that the flight control system of this series of aircraft had the problem of wrong reading output, which might cause the aircraft to dive and fall at a large angle by itself.

Comparing the two air crashes, it is difficult for lion air to receive a false signal from the aircraft signal system, indicating that the aircraft is "looking up", so the control system keeps giving instructions of "looking down". The unit was entangled with the control system for a long time, and finally something happened.

This time, the flight of Egypt Air also experienced an abnormal climb and fall, and the flight speed was overspeed.

It is a long process from the manufacturer to the airline until the plane is retired. Continuous airworthiness management runs through the whole life cycle, and the responsibility for continuous airworthiness is jointly fulfilled by the flight safety supervision department of airworthiness authorities, aircraft operators and aircraft manufacturers. Any party's dereliction of duty may cause huge security risks.

We need to wait for the public results of the investigation before we can make a decision on the cause of the Boeing plane crash.
