The aircraft dived to an altitude of 7,400 feet (2,200 meters), then dived again, before regaining about 1,200 feet (360 meters). It crashed into a mountainside in a remote, forested area outside of Wuzhou city.

State media and Chinese regulators gave no indication that the pilot had reported trouble or other information that could shed light on the cause of the disaster. The aircraft stopped transmitting data 96 seconds after it began to crash.

Rescuers planned to use drones to search for the plane’s black boxes; These boxes will contain information from the instruments and sounds from the cockpit.

Confirming the cause of an airplane crash sometimes takes months or years due to the need to collect badly damaged debris and examine specific technical factors.

HOW MANY PEOPLE ARE ON BOARD? DID ANY SURVIVE?

The plane was carrying 123 passengers and nine crew members from the city of Kunming. Chinesefrom southwest to Guangzhou, an export hub in southeast.

No survivors were found as rescuers searched the rugged, charred mountainside in the subtropical Guangxi region.

IS THIS THE SAME BOEING THE MODEL IN THE PREVIOUS SOLUTIONS RESULTING TO BE RESOLVED IN THE OLD SOLUTIONS?

No. a crashed plane boeing 737-800, not Boeing The 737 Max is a newer model that has been temporarily discontinued worldwide after two fatal crashes in Indonesia in 2018 and Ethiopia in 2019.

The 737-800 is a twin-engine, single-aisle aircraft commonly used for short- and medium-haul flights. In a typical configuration, it has 178 seats split between the main and premium cabins. boeing delivered more than 5,100 of these in the last 24 years and Chinese It is the largest market at around 1,200 according to aviation consultant IBA.

Hassan Shahidi, head of the Flight Safety Foundation, said the aircraft has been flying since 1998 and has an excellent safety record. They were involved in 22 accidents that damaged the planes beyond repair and killed 612 people.

China Eastern grounded all of its 737-800s after the crash. ChineseMinistry of Transport announced.

Boeing The 737 Max, which entered service in 2017, was stopped by regulators after two accidents. They were blamed on a computer system that pushed the nose down in flight, which could not be overridden by the pilots.

Airlines are allowed to continue using the 737 Max. boeing Redesigned the system in a process overseen by regulators from the United States and Europe, Chinese and the Middle East.

HOW WILL THE RESEARCH BE?

Chinese A representative from the US crash investigator called the National Transportation Safety Board, and also boeing and CFM, the General Electric-Safran joint venture that made the engines for this aircraft.

The key to the investigation is rescuing the so-called black boxes – they’re often painted orange for visibility, but the name has long stuck. A device called a flight data logger collects information about the aircraft’s airspeed, altitude, up or down direction, pilot actions, and performance of all important systems. Cockpit audio recording captures sounds during flight, including conversations and background engine noise.

Investigators will look at the aircraft’s maintenance history, pilots’ training and records, pilots’ communication with air traffic control, and weather data. They’ll examine parts of the wreckage for clues. Even the size of the debris field is important – when debris is spread over a very large area, it can indicate that the aircraft dissipated before hitting the ground.

DOES LANDING THE AIRCRAFT INCREASED THE FINDING OF THE CAUSE?

As long as the black boxes survive and can be downloaded, researchers should be able to get a good idea of ​​what’s going on.
