WASHINGTON, Oct. 29 -- Boeing CEO Dennis Muilenburg acknowledged mistakes as he testified before the U.S. Congress for the first time since two deadly air crashes of its 737 Max planes that killed 346 people, but he deflected tough questions such as why the company withheld details about its flawed new automated system.
Muilenburg told the Senate Commerce Committee on Tuesday that "we know we made mistakes and got some things wrong."
However, pressed by U.S. lawmakers over how did the jet airliners with a risky flight control system already known to the company before the crashes kept flying, Muilenburg provided few details, and Senator Tammy Duckworth described his speech as "half-truths."
Specifically, Muilenburg was repeatedly grilled at the hearing about delays in turning over internal messages that described erratic behavior of the flight control software in a simulator.
The U.S. Federal Aviation Administration (FAA) said Boeing covered up messages made by its two employees in 2016 when a Boeing pilot told his co-workers that the flight handling system was "running rampant" during simulator tests.
The pilot said "this was egregious," but "I basically lied to regulators (unknowingly)," according to the message transcript.
Both accidents -- Indonesia's Lion Air crash in October 2018 and Ethiopian Airlines crash this March -- involved the repeated activation of a flight control software function called MCAS, which responded to erroneous signals from a sensor that measures the airplane's angle of attack, wrote Muilenburg in a written testimony.
