Boeing 2016 internal messages suggest employees may have misled FAA on 737 MAX: Sources

WASHINGTON: Boeing Co turned over instant messages from 2016 between two employees that suggest the airplane maker may have misled the Federal Aviation Administration about a key safety system on the grounded 737 MAX, according to documents seen by Reuters.

The FAA confirmed Friday that Boeing told it a day earlier about internal messages it had discovered "some months ago" that characterise "certain communications with the FAA during the original certification of the 737 MAX in 2016."

The FAA said it found the messages "concerning" and "is reviewing this information to determine what action is appropriate." It prompted a letter from FAA Administrator Steve Dickson to Boeing Chief Executive Dennis Muilenburg demanding an "immediate" explanation for the delay in turning over the documents.

A person briefed on the matter said Boeing failed to turn over the documents to the FAA for four months and that the Justice Department is also in possession of the messages.

The Boeing internal messages raised questions about the performance of the so-called MCAS anti-stall system that has been tied to the two fatal crashes in five months.

The messages are between the MAX's then-chief technical pilot, Mark Forkner, and another Boeing pilot, the sources said, and raised questions about the MCAS's performance in the simulator in which he said it was "running rampant."

Forkner has since left Boeing. The Seattle Times reported in September that Forkner repeatedly invoked his Fifth Amendment right to not turn over documents subpoenaed by the Justice Department.

Boeing said in a statement the company "brought to the Committee's attention a document containing statements by a former Boeing employee."

Forkner said in one text message, "I basically lied to the regulators (unknowingly)." The other employee responded that "it wasn't a lie, no one told us that was the case" of an issue with MCAS.

Forkner responded soon after: "Granted I suck at flying, but even this was egregious."

The FAA plans to turn over more communications from Forkner to Congress later on Friday, sources said.
