A Turkish passenger plane nearly crashed into the sea. What are the main reasons for frequent passenger plane accidents?
The main causes of passenger aircraft accidents are: 1. Natural factors: bad weather and electromagnetic wave interference; 2. Human factors: pilot control errors, ground staff maintenance errors, pilot/ground staff communication errors and aircraft communication errors. Collision; 3. Hardware failure: engine failure, hydraulic failure, fuel tank failure and metal fatigue, etc.
A Turkish passenger plane skidded off the runway while landing at Trabzon Airport in the northeast of the country late at night on the 13th and almost fell into the Black Sea.

The plane was flying from Ankara to Trabzon that night. It was a Boeing 737-800. There were 162 people on board after the accident. All passengers and six crew members were evacuated and there were no casualties. It is still unclear what caused the accident, and relevant investigation work has been launched.
We all know that the consequences of a plane crash are very serious, so what are the causes of plane accidents?

Natural factors:
1. Bad weather
For example, dense fog, lightning strikes , due to the ice on the wings caused by the cold weather, and the wind shear encountered by the aircraft during takeoff and landing, which is commonly known as "strange wind".
2. Electromagnetic wave interference
According to statistics, in recent years, more than 20 flight accidents caused by electromagnetic wave interference have occurred around the world every year. Therefore, many airlines around the world stipulate that aircraft Cell phone use is prohibited while flying. In addition, electromagnetic waves generated by astronomical phenomena such as sunspots and northern lights can also interfere with the normal navigation of aircraft.
3. Big bird attack
Human factors:
1. Pilot control error
2. Ground crew maintenance error
?
Improper loading and unloading by ground staff, illegal maintenance, etc. This is equivalent to placing a time bomb on the aircraft, and an accident may occur at any time.
3. Pilot/ground crew communication error
Hardware failure
1. Engine failure
2. Hydraulic failure
On a passenger aircraft, hydraulic pipelines connect the pilot's pedals and handles to all control surfaces of the aircraft, ailerons, lift surfaces, etc. It can be said that the aircraft is completely controlled by its hydraulic system.
3. Fuel tank explosion
The accident is mainly caused by static sparks igniting fuel vapor in the fuel tank.
4. Metal fatigue
When the aircraft is flying, it will produce vibrations of various frequencies, coupled with the pressure increase/decompression cycle of each takeoff and landing, if any parts are not inspected If fatigue fracture occurs, an accident may occur.
Plane crashes are very scary. To further reduce the incidence of aircraft accidents, airlines had better take preventive measures.
