According to an ABC report on May 23, US Boeing Chief Financial Officer Brian West said that the company will run out of cash in 2024, and there will be no improvement in aircraft deliveries in the second quarter. According to reports, Boeing spent nearly 4 billion US dollars (about RMB 29 billion) in cash in the first quarter. West said that the situation in the second quarter may be similar to the first quarter, or even “probably worse.” In January of this year, the door stopper of an Alaska Airlines Boeing 737 MAX 9 passenger plane fell off during the flight, triggering questions from various circles about Boeing's quality control and safety culture. The US government also stepped up its scrutiny of the company. At the end of February, the FAA restricted Boeing production of 737 MAX airliners and ordered Boeing to submit a comprehensive rectification plan within 90 days to “resolve systemic quality control issues.”
