(Bloomberg) -- The Federal Aviation Administration released multiple steps it plans to take to change how it reviews aircraft designs, a process that was criticized after two fatal crashes on Boeing Co.’s 737 Max.

The agency is planning on updating regulations to require better internal safety systems at planemakers and is reexamining how it assumes pilots will react to failures, the agency said in a report to the Department of Transportation Tuesday.

The report is a response to a blue-ribbon panel’s review in January that found agency needed to update its practices. The 737 Max, Boeing’s best-selling jet, was grounded in March 2019 after a the second of two fatal crashes linked to automated safety system that drove down the nose due to a malfunction.
