Boeing, FAA Oversight of 737 Max Was Flawed: Seattle Times
(Bloomberg) -- In one of the most detailed descriptions yet of the relationship between Boeing and the Federal Aviation Administration during the 737 Max’s certification process, the Seattle Times reported Sunday that the U.S. regulator delegated much of the safety assessment to Boeing and that the analysis the planemaker in turn delivered to the authorities had crucial flaws.
The newspaper’s report was based on interviews with current and former engineers directly involved or familiar with the evaluations, all of whom asked not to be identified, and was under way even before the Ethiopia crash.
Boeing told the newspaper Saturday that the FAA had reviewed the company’s data on the plane and “concluded that it met all certification and regulatory requirements.” The company, which is based in Chicago but designs and builds commercial jets in the Seattle area, said there are “some significant mischaracterizations” in the engineers’ comments.
Boeing’s System Safety Analysis of the flight control software -- suspected to have contributed to the Lion Air jetliner crash in October and also under the spotlight in the Ethiopia accident -- understated the power of the system, the engineers told the Seattle Times. The newspaper said the analysis also failed to account how the system could reset itself each time a pilot responded -- in essence, gradually ratcheting the horizontal stabilizer into a dive position.
