US Congress Announces Receipt of Documents of Concern on Boeing 737 MAX Disturbing new papers on Boeing's response to the safety concerns surrounding the 737 MAX have been forwarded to the U.S. Congressional Transportation Committee, a congressional adviser said. Boeing forwarded new documents to the U.S. Congressional Transportation Committee Monday evening that raise concerns about the company's response to the safety concerns surrounding the 737 MAX, a congressional adviser said Tuesday, Dec. 24. Boeing sent the documents "late in the evening," after the announcement of the immediate resignation of its executive director, Dennis Muilenburg, said the committee's assistant, which is currently investigating the 737 MAX, which has been grounded since March 13 following two fatal accidents. However, he did not specify whether these documents related to the situation before or after the accidents of Lion Air and Ethiopian Airlines, which occurred at the end of October 2018 and 10 March respectively, AFP informs AFP. Concerns The assistant stated that it was Boeing that transmitted, on its own initiative, these documents, the exact content of which was not revealed. "Staff continues to review these records, but like other records previously disclosed by Boeing, they appear to show a very disturbing picture regarding two concerns expressed by Boeing employees, about the company's commitment to safety, and the efforts of some employees to ensure that Boeing's production projects are not thwarted by regulators or others," he explained. Multiple investigations by aviation authorities in Indonesia, where Lion Air's plane crashed, as well as in Ethiopia following the crash of an Ethiopian Airlines aircraft, have implicated the aircraft's MCAS stall-protection software. They also uncovered other shortcomings on the part of the manufacturer, such as a lack of pilot information. In the United States, investigations in parliamentary committees have also revealed a very close relationship between the Federal Aviation Administration (FAA) and the manufacturer, as the federal authorities have left entire sections of the 737 MAX certification process in the hands of Boeing. A "necessary" change of direction On Monday, Boeing announced the immediate resignation of Dennis Muilenburg, who was heavily criticized for his handling of the 737 MAX crisis. "The Board of Directors has decided that a change of leadership is necessary to restore confidence in the company as it strives to re-establish links with regulators, customers and all other stakeholders," the company said. "Dennis Muilenburg's ouster was long overdue," said Congressman Peter DeFazio, chairman of the Congressional Transportation Committee, who said that "under his leadership, a long-admired company had made a number of devastating decisions suggesting that profit took precedence over safety.
