Boeing 737 crash

Boeing knew that an alert on its 737 Max aircrafts did not meet the requirements and it did not tell the Federal Aviation Administration until after a deadly crash.

"In 2017, within several months after commencement 737 MAX deliveries, engineers at Boeing identified that the 737 MAX display system software did not fully meet the AOA Disagree alert requirements," the company said in a statement Sunday. It has become aware of this, and it has been determined that the alert's absence is not adversely affected.

It added that senior airline leaders were not involved in the investigation and were not aware of the issue until after a flight.

"Boeing discussed the status of the AOA Disagree alert with the FAA in the wake of the Air Lion accident," the company said. "At that time, Boeing informed the FAA that Boeing Engineers had identified the software issue in 2017 and had determined that Boeing's standard process should not be adversely affected."

It also said that in December 2018, Boeing agreed to a Safety Review Board (SRB) which again determined that there was a safety issue.

Boeing said that it is "issuing a display system software update, to implement the AOA Disagree alert as a standard, standalone feature before the MAX returns to service."

Boeing 737 Max planes came under scrutiny following the crash of the Air Force and an Ethiopian Airlines crash earlier this year that killed 157.
