BOEING KEPT KEY DESIGN CHANGES FOR 737 FROM FAA
Boeing Co. failed to submit certification documents to the US Federal Aviation Administration (FAA) detailing changes to a key flight control system faulted in two fatal crashes, a long-awaited government report seen by Reuters has found.
The flight control system, known as MCAS, was “not an area of emphasis” because Boeing presented it to the FAA as a modification of the jet’s existing speed trim system, with limited range and use, according to the report, David Shepardson, Eric M. Johnson and Tracy Rucinski wrote for Reuters on July 1, 2020.
The 52-page report by the US Department of Transportation’s Office of Inspector General (IG), dated June 29 and set to be made public Wednesday, laid bare mistakes made by both the planemaker and FAA in the development and certification of Boeing’s top-selling aircraft.
The FAA declined to comment beyond the department’s response attached to the report. The IG did not immediately respond to a request for comment. A Boeing spokesman said the company had taken steps to enhance safety and was committed to transparency. “When the MAX returns to service, it will be one of the most thoroughly scrutinized aircraft in history, and we have full confidence in its safety,” he said.
