A Boeing 737 MAX jet, piloted by Federal Aviation Administration (FAA) chief Steve Dickson, takes off on a test flight from Boeing Field, Wednesday, Sept. 30, 2020, in Seattle.
The MAX was grounded worldwide in early March 2019 after the second of two fatal accidents that together killed 346 people aboard almost-new aircraft.
An FAA spokesman said Boeing pilots would also be on the plane when it takes off from the former Boeing Field in the Seattle area.
Boeing hopes to win FAA approval later this year for changes it has made to flight-control software and computers.
The bill would also require plane manufacturers to tell the FAA, airlines and pilots about automated systems that can alter a plane’s path.
