China is still holding on as Boeing 737 Max can fly again in Australia

Australia is the latest to cancel ground orders for a Boeing 737 Max Plus: everything you need to know about the plane.Nearly two years after being banned from flying, the Boeing 737 Max has been cleared back to the skies in the United States, Brazil, Canada, Australia, the UK and the European Union. Based on their decision, the aviation safety agency ordered Boeing and airlines to repair the flight control system, both allegedly crashes, leading to the ban. Update the operating manual And increase pilot training However, China, the world's second-largest commercial air traffic market, still bans planes from taking off and has yet to specify when planes will reverse.

The crashed plane was landed around the โปรโมชั่นสล็อต world in March 2019, after two plane crashes in Indonesia and another in Ethiopia killing a total of 346 people. In addition to the human tragedy, it was devastating. To Boeing's business as the company has placed orders for thousands of 737 Max books. In addition to the flight control systems at the center of both investigations, other reports address concerns about the airline's flight control computers, wires and engines.For the time it takes for each airline to add airlines back to their schedule, the schedule is based on necessary repairs and changes. But even if the planes are flying around the world again, Boeing will have to work vigorously to maintain the trust of the airline and the public associated with the Max family.Here's everything we know about what happened to the airline. fly

What happened in both crashes?

The first crash occurred on Oct. 29, 2018. Lion Air Flight 610 landed in Java, 13 minutes after take-off from Jakarta, Indonesia, killing 189 people. It wasn't long before it lost control. That plane was almost brand new when it arrived in Lion Air three months earlier.The second accident occurred on March 10, 2019, when an Ethiopian Airlines flight 302 took off from Addis Ababa Bole International Airport for Nairobi, Kenya. After take off, the pilot sent a distress signal and was immediately allowed to return and land. But before the crew could return, the plane crashed 40 miles from the airfield, six minutes after exiting the runway. On the ship there were 149 passengers and eight crew members. The aircraft involved were only four months old.

What caused the crash?

Plane crashes rarely have a single cause, which is the case.On October 25, 2019, the Indonesian National Transportation Safety Board released the final report on Lion Air crashes. The report identified nine factors that led to the crash. But most blame the MCAS before the crash.Lion Air pilots were unable to determine their true speed and altitude, and they attempted to steer the plane as the plane vibrated for about 10 minutes every time it took off. From the dive, the MCAS depresses the nose again.The MCAS function is not a unsafe design and does not include redundancy," the report said. The researchers also found that the MCAS relied on a single sensor, which was faulty and that the flight crew were not adequately trained to use the system. this Improper maintenance procedures, confusion in the cockpit and the absence of a cockpit warning light. (See next question) also contributed to the error.

On March 9, 2020, nearly a year a day since the plane crash in Addis Ababa, the Ethiopian Airplane Accident Investigation Agency released an interim analysis. Like the Indonesian findings, it cites design flaws with the MCAS, such as the dependence of a single attack angle sensor. It also blames Boeing for not providing enough crew training on the use of Max's unique systems (the Seattle Times has insights into the report).Unlike their Indonesian counterparts, Ethiopian researchers did not address maintenance issues and did not condemn the flight crew. "The aircraft has a valid Airworthiness Certificate and is maintained in accordance with applicable regulations and procedures," the report states. "There were no known technical issues prior to departure.Keep in mind that the investigation of a mistake is extremely complex, it takes months to assess the evidence and identify the possible causes. The researchers had to examine the debris, study the flight recorders, and, if possible, examine the victim's body for the cause of death. It also involves many divisions such as airlines, aircraft and engine manufacturers, and aviation regulators.

What is the Boeing 737 Max?

Built to compete with the Airbus A320neo, the 737 Max is a family of commercial aircraft made up of four of the most popular models, the Max 8, first flown on January 29, 2016 and entered service to passengers with Malin Airlines.
