The move comes as Boeing attempts to regain the trust of regulators, airlines and, most of all, the public. In October, it came out that one of the company’s employees may have inadvertently misled the FAA about the performance of the 737 Max’s MCAS anti-stall technology. The employee told another pilot that he had “basically lied” to the regulator about the tech during the plane’s certification.

“The Board of Directors decided that a change in leadership was necessary to restore confidence in the Company moving forward as it works to repair relationships with regulators, customers, and all other stakeholders,” the company said. “Boeing will operate with a renewed commitment to full transparency, including effective and proactive communication with the FAA, other global regulators and its customers.”

Earlier this month, Boeing said it will suspend 737 Max production in January. The company has approximately 400 completed aircraft waiting in storage. Whether or not they’ll be able to fly will depend on regulators are happy with the company’s actions.

The FAA tentatively approved the updates in March, but the software still needs to undergo FAA testing in order to receive certification. At the moment, Boeing is providing the FAA with additional information, including details on how pilots interact with the airplane controls and displays in different flight scenarios. “We’re committed to providing the FAA and global regulators all the information they need, and to getting it right,” Boeing’s CEO Dennis Muilenburg said in a statement.

As previously reported, the updated anti-stall Maneuvering Characteristics Augmentation System (MCAS) will compare data from both of the plane’s angle-of-attack sensors, rather than just one. If there’s a discrepancy of 5.5 degrees or more, the system won’t kick in. And, in the event of an incident, crews will be able to counteract the system if necessary. Boeing says it has flown the 737 Max with the updated MCAS software for more than 360 hours on 207 test flights. It also conducted simulator testing, and it will participate in a series of global customer conferences before the planes are cleared for flight.
