On the other hand, China's first domestic large aircraft C919 is also about to be delivered. Who can make progress first and attract market attention as reported by Bloomberg on November 15, Boeing is optimistic that its 737max aircraft will soon receive orders and delivery from China. The CEO of the company said last month that he was optimistic that China would re certify 737 Max by the end of this year observer.com noted that before the 737max grounded, a quarter of Boeing's annual aircraft were sold to Chinese buyers, and China is Boeing's largest customer. And after the 737MAX was grounded, COVID-19 has been affected by Boeing for eight consecutive quarters. p> Reuters commented that China has the largest aircraft market in the world. If Boeing can return to China, it will be a great blessing for the company. Jefferies, a brokerage, also said in September that the progress would boost the company's share price by at least 5% "we are full of hope," said Stan deal, head of Boeing's commercial aircraft department, in an interview with US media on November 14 local time. "We have received some aircraft orders and are encouraged. We know that the leaders of China and the United States will hold talks next week, so these are encouraging signs" Boeing's "hopeful" is not groundless. Prior to the company's statement, the Civil Aviation Administration of China recently issued a notice on Soliciting Opinions on 737max airworthiness directive, which triggered extensive discussion in the aviation industry the notice mentioned that two air crashes occurred successively for the 737-8 aircraft of the Boeing 737max series, lion air Indonesia and Ethiopian Airlines. The investigation results showed that the two accidents occurred because when the Boeing 737-8 aircraft was in manual flight and the flaps were retracted, the wrong high angle of attack input repeatedly activated the maneuver characteristic enhancement system, resulting in repeated low head trim of the horizontal stabilizer, Under the interference of multiple alarms, the flight crew could not effectively identify and locate the fault and take measures, resulting in the loss of control of the aircraft the notice points out that in order to solve the unsafe state of 737-8 aircraft maneuverability enhancement system (MCAS) in 737max series, Boeing has started the design change of flight control system software and display system software. CAAC is revising the flight control system software design change, display system design change, Aircraft Flight Manual submitted by Boeing After a comprehensive evaluation of the relevant corrective measures such as horizontal stabilizer trim harness laying and modification, it is confirmed that the relevant corrective measures can eliminate the above unsafe state according to the notice, in order to eliminate unsafe conditions, CAAC issued this airworthiness directive, requiring domestic airlines to implement corrective measures such as the installation and verification of flight control computer operating program software (FCC OPS); The deadline for comments is November 26, 2021 this notice was interpreted by Reuters and other foreign media as that China is about to allow 737max to go around in China, because Chinese aviation regulators are "satisfied" that the 737max aircraft design revision launched by Boeing may solve the safety problem in fact, CAAC has been asked about the progress of 737max go around for many times, and the Department has always stressed the "three principles of go around": that is, after confirming that the airworthiness of the aircraft has been re approved, the required aircraft modification and pilot training have been effectively implemented, and the safety problems pointed out in the conclusion of accident investigation have been solved accordingly to ensure flight safety, Will resume the commercial operation of Boeing 737 max8 in response to the above notice for comments issued by China Civil Aviation Administration, industry experts quoted by global times believe that this shows that 737max has basically met the "three principles of go around" and can enter the technical procedure of airworthiness certification "in other words, 737max has obtained the 'examination permit' and can take the 'examination' after the deadline for comments to seek formal approval for go around". However, the expert said that even if the "examination" is passed, it will take time for domestic airlines to refit aircraft and train pilots

737MAX is an important source of revenue for Boeing, which has been overloaded by COVID-19 and Boeing has suffered heavy losses. The third quarterly report of 2021 shows that Boeing's revenue is US $15.28 billion, an increase of 8% year-on-year, lower than the market expectation of US $16.3 billion; The net loss under GAAP (general accounting standards) was $132 million, compared with a loss of $466 million in the same period last year, which is the eighth consecutive quarterly loss of the company Dave Calhoun, CEO of Boeing, said at the third quarter earnings conference that he was optimistic that China would re certify 737max by the end of this year, which would "clear the way" for resuming delivery to China in the first quarter of 2022. At the same time, this is also the key factor for the company to increase the output of 737max from 19 per month to 31 per month next year Reuters reported that the Boeing team visited China earlier this year for technical flight test and simulation training, and evaluated the revised pilot training course. Deere, head of Boeing's commercial aircraft department, said: "our job is to provide every bit of technical information for their evaluation. We are checking, but it ultimately depends on the Civil Aviation Administration of China." Boeing disclosed last month that about one-third of the 370 undelivered 737max aircraft in its inventory are prepared for Chinese customers as Boeing looks forward to the 737max go around in China, China's large domestic aircraft C919 is about to usher in an important moment. In March this year, when China Eastern Airlines and COMAC officially signed the purchase contract of domestic large aircraft C919, it was revealed that the first C919 will be delivered this year and put into operation in 2022 on September 10, the intermediate meeting of C919 aircraft production license approval committee was held in Shanghai. This meeting was held against the background that the first aircraft of C919 batch production is about to enter the final assembly stage, marking that phased progress has been made since the start of C919 aircraft batch production in 2019, which is an important milestone of C919 project although the total of C919The installation base is in Pudong, Shanghai. However, since the approved flight test of C919 needs to be carried out under various climatic conditions, all six C919 flight test aircraft are "on business" and open the multi airport and multi regional cooperative flight test mode on November 12, Zhao yuerang, deputy party secretary and general manager of COMAC, visited Yanliang test flight site of C919 project. He pointed out at the scene that he firmly won the C919 flight test and evidence collection task with his unrelenting perseverance; We should understand and master the law and carry out work according to the law of commercial aircraft development; We should strengthen unity and cooperation, unite all forces that can be united, work hard and continue to struggle, and unswervingly take the long march of the cause of large aircraft in the new era source | observer network
