Technology Boeing reportedly misled FAA about safety of its grounded 737 Max jets
As a safety report faults Boeing and the FAA, it's still unclear when the 737 Max will fly again
The 737 Max 8 had two deadly crashes in five months, and authorities are zeroing in on what went wrong. Plus: Everything you need to know about the plane.The 737 Max 9, shown here at the 2016 Paris Air Show, is a larger version of the Max 8, but with the same piloting system that's under investigation.
Instant messages from 2016 suggest that Boeing may have misled the Federal Aviation Administration about a controversial safety system of its grounded 737 Max jets,. The messages, between two Boeing employees, raise questions about the safety of the MCAS software that is thought to have , killing a total of 346 passengers.
In the messages, a Boeing pilot named Mark Forkner griped that the MCAS system was making the plane difficult to fly the 737 Max in simulation, according to a. “Granted, I suck at flying, but even this was egregious,” Forkner said, according to a transcript reviewed by the Times.

Forkner, who is the chief technical pilot for the 737, went on to admit that he may have misled safety regulators about the plane. “I basically lied to the regulators (unknowingly),” he said, according to the Times. The messages are from November 2016, eight months before Forkner made a request to the FAA to remove mention of MCAS from the pilot’s manual. The FAA, believing MCAS could only be activated in rare cases, approved the request.
Boeing discovered the messages “months ago,” but only recently turned them over to the Department of Transportation. In a letter to Boeing CEO Dennis Muilenburg, FAA Administrator Steve Dickson calls the messages “concerning” and demands to know why Boeing delayed turning them over to regulators. Muilenburg is expected to testify before Congress later this month.

After the first crash in October 2018, an agency analysis showed a good chance the Lion Air malfunction would happen again. But the FAA followed Boeing’s lead on key aspects of the response, setting the stage for the second fatal crash months later.A Federal Aviation Administration analysis showed a good chance the same malfunction would crop up again, according to agency officials and people briefed on the results. Even under the most optimistic scenario, the agency’s statistical models projected a high likelihood of a similar emergency within roughly a year.

MCAS, which stands for Maneuvering Characteristics Augmentation System, is a software unique to Boeing’s 737 Max jets that takes sensor data to determine how much the plane’s nose is pointing up or down relative to oncoming airflow. When MCAS detects that the plane is pointing up at a dangerous angle, it can automatically push down the nose of the plane in an effort to prevent the plane from stalling.
A preliminary report from Indonesian investigators indicates that Lion Air 610 crashed because a faulty sensor erroneously reported that the airplane was stalling, triggering the MCAS system which then tried to point the aircraft’s nose down so that it could gain enough speed to fly safely.
The report comes as Boeing is. The planes have been grounded since March 2019, when Ethiopian Airlines 302 went down. The move put enormous strain on carriers, which struggled to shift the planes out of service while minimizing the impact on customers. Boeing is expected to submit its final certification package to the FAA later this year.
The FAA did not immediately respond to a request for comment. A spokesperson for Boeing provided the following statement:
“Over the past several months, Boeing has been voluntarily cooperating with the House Transportation & Infrastructure Committee’s investigation into the 737 MAX. As part of that cooperation, today we brought to the Committee’s attention a document containing statements by a former Boeing employee. We will continue to cooperate with the Committee as it continues its investigation. And we will continue to follow the direction of the FAA and other global regulators, as we work to safely return the 737 MAX to service.”
