Events before and after the plane crashed into MU5735 (preliminary investigation results of the cause of the accident)

On September 28th, 20 18, a MU5735 flight from Xiamen to Fuzhou crashed shortly after takeoff, killing 59 people and injuring 37 others. The preliminary investigation of the cause of the accident showed that the cause of the plane crash was that the pilot did not check according to the standard operating procedures before taking off, which led to the imbalance of the center of gravity of the plane.

Operating steps before the accident

Before the plane takes off, the pilot needs to check according to the standard operating procedure to ensure the plane takes off safely. The specific operation steps are as follows:

Step 1: Check the outside of the plane.

Pilots need to check whether there are abnormalities outside the aircraft, such as damage and foreign objects.

Step 2: Check the inside of the plane.

Pilots need to check whether there is any abnormality inside the aircraft, such as oil leakage and failure.

Step 3: Check the hatch and seat belt.

The pilot needs to check whether the hatch is closed and locked, and whether the passenger's seat belt is fastened.

Step 4: Check the dashboard and controller.

Pilots need to check whether the instrument panel and controller are working normally, such as whether there are faults, errors, etc.

Step 5: Check the balance of the center of gravity.

Pilots need to check whether the balance of the center of gravity of the aircraft is appropriate, such as whether there is any deviation and whether it needs to be adjusted.

Preliminary investigation results of accident cause

The preliminary investigation of the cause of the accident showed that the cause of the plane crash was that the pilot did not check according to the standard operating procedures before taking off, which led to the imbalance of the center of gravity of the plane. Specifically, when the pilot checked the balance of the center of gravity, he did not follow the standard operating procedures, which caused the center of gravity of the aircraft to tilt backward, which caused the aircraft to fail to maintain its balance during take-off and eventually crashed.

The preliminary investigation results of the cause of the accident also show that the pilot did not use the standard calculation method of center of gravity balance, but used an inaccurate method. This is also one of the causes of the accident.
