A document has appeared which shows that a Boeing engineer was concerned that the 737 Max lacked sufficient safety systems.
A Boeing engineer asked in 2015, more than a year before the planes were certified by federal regulators, whether a flight-control system that was involved in both deadly crashes, was safe because it relied on a single sensor.
The document was released on the second of two tense days of testimony by Boeing’s CEO Dennis Muilenburg on Capitol Hill this week where lawmakers probed the manufacturer’s CEO over two fatal crashes of the jetliners, and repeatedly asked why he hasn’t resigned or given up his pay.
Muilenburg stressed there are no plans for him to resign despite immense pressure amid the 737 MAX crisis saying that he feels responsible to lead the company through the 737 Max troubles.
During the hearing, Muilenberg said: "I am responsible. I take responsibility for these two accidents that occurred on my watch.
"I don't want to run away from challenges. My intent is to see this through," Muilenburg added. "That's part of what I owe to these families… To me, this is about being responsible and ensuring safe travel for the future."
The 737 Max crashes — one in Indonesia in October 2018 followed by another in Ethiopia in March — has prompted Boeing to revamp the system to rely on two sensors.
The jets have been grounded worldwide since the second fatal crash in March. Together, the crashes killed all 346 people on the two flights.
