The letter to the Senate, a copy of which was obtained by The Seattle Times, was written by engineer Curtis Ewbank, a 34-year-old specialist in flight-deck systems whose job when the MAX was in early stages of development involved studying past crashes and using that information to make new planes safer.
His letter, sent earlier this month, argues that it’s not enough for Boeing to fix the flawed Maneuvering Characteristics Augmentation System (MCAS) that’s known to have brought down the aircraft in two crashes in Indonesia and Ethiopia.
“I have no doubt the FAA and lawmakers are under considerable pressure to allow the 737 MAX to return to service as quickly as possible and as soon as the public MCAS flaw is fixed,” Ewbank told the Senate. “However, given the numerous other known flaws in the airframe, it will be just a matter of time before another flight crew is overwhelmed by a design flaw known to Boeing and further lives are senselessly lost.”
He goes on to suggest similar shortcomings in the flight-control systems may affect the safety of Boeing’s forthcoming 777X widebody jet.
Ewbank’s letter also reveals that he has been interviewed about his concerns by the FBI, which suggests his allegations have at least been considered as part of the Justice Department’s probe into what went wrong on the 737 MAX and whether the actions of anyone at Boeing were criminal.
