senior Boeing engineer filed an internal ethics complaint this year saying that during the development of the 737 Max jet the company had rejected a safety system to minimise costs, equipment that he felt could have reduced risks that contributed to two fatal crashes.
Boeing has provided the complaint, which was reviewed by The New York Times, to the department of justice as part of a criminal investigation into the design of the Max, according to a person with knowledge of the inquiry who requested anonymity given the ongoing legal matter.
Federal investigators have questioned at least one former Boeing employee about the allegations, said another person with knowledge of the discussions who similarly requested anonymity.
