Boeing CEO accused of telling ‘half-truths’ in 737 Max hearing

WASHINGTON Dennis Muilenburg faced intense grilling by U.S. lawmakers at a hearing on Tuesday over what the company knew about its MCAS stall-prevention system linked to two deadly crashes, and about delays in turning over internal 2016 messages that described erratic behaviour of the software in a simulator.
The hearing, the highest-profile congressional scrutiny of commercial aviation safety in years, heaps pressure on a newly rejiggered Boeing senior management team fighting to repair trust with airline customers and passengers shaken by an eight-month safety ban on its 737 Max following the crashes, which killed 346 people.
“You have told me half-truths over and over again,” Sen. Tammy Duckworth told Muilenburg, questioning why the manufacturer did not disclose more details about MCAS’s lack of safeguards. “You have not told us the whole truth and these families are suffering because of it.”
Duckworth said the pilots did not know enough about MCAS. “You set those pilots up for failure.”
Muilenburg acknowledged errors in failing to give pilots more information on MCAS before the crashes, as well as for taking months to disclose that it had made optional an alarm that alerts pilots to a mismatch of flight data on the 737 Max. “We’ve made mistakes and we got some things wrong. We’re improving and we’re learning,” he said.
Sen. Jon Tester noted Boeing had won approval from the Federal Aviation Administration (FAA) to avoid having to add new crew alerts because it would have been expensive. “It wouldn’t have happened if FAA would have been doing their job and it also wouldn’t have happened if you had known what the hell was going on,” he said.
Tester said wide-scale changes were needed. “I would walk before I would get on a 737 Max. ... I see corners being cut.”
Senators suggested Boeing had not been completely honest and expressed dismay that the 2016 instant messages did not prompt an immediate reaction from the firm.
