The Roots of Boeing’s 737 Max Crisis: A Regulator Relaxes Its Oversight

In the days after the first crash of Boeing’s 737 Max, engineers at the Federal Aviation Administration came to a troubling realization: They didn’t fully understand the automated system that helped send the plane into a nose-dive, killing everyone on board.
Engineers at the agency scoured their files for information about the system designed to help avoid stalls. They didn’t find much. Regulators had never independently assessed the risks of the dangerous software known as MCAS when they approved the plane in 2017.
More than a dozen current and former employees at the F.A.A. and Boeing who spoke with The New York Times described a broken regulatory process that effectively neutered the oversight authority of the agency.
The regulator had been passing off routine tasks to manufacturers for years, with the goal of freeing up specialists to focus on the most important safety concerns. But on the Max, the regulator handed nearly complete control to Boeing, leaving some key agency officials in the dark about important systems like MCAS, according to the current and former employees.
