Boeing didn’t instantly reply to a request for remark.
Mr. Elwell's testimony comes hours after a tape was launched from a gathering between US pilots and Boeing final yr, following the Lion Air accident, throughout which pilots flew complained of not realizing sufficient concerning the MCAS system.
"These guys didn’t even know this rattling system was put in within the aircraft," mentioned a pilot, apparently referring to Lion Air pilots. "Nobody else both."
Within the tape offered to CBS Information and different US media, a Boeing official replies, "I have no idea if understanding this method would have modified the result of this operation. Over 1,000,000 miles, you could be flying this aircraft and possibly when you'll see that ever. "

Mr. Elwell didn’t say whether or not senior FAA officers had additionally participated in MCAS certification alongside engineers and take a look at pilots, on account of a report. revealed Tuesday that they’d not, regardless of the chance of catastrophe if it failed.
