We have enjoyed living in the safest time for aviation travel in history, and Boeing and the Federal Aviation Administration (FAA) deserve much of the credit for that. The recent crashes of two Boeing 737 Max 8 airplanes, however, demonstrate that aviation would be even safer if the FAA acted more swiftly and decisively after an airline disaster to address identified safety hazards.
The FAA could make everyone safer if it fulfilled its duty to independently confirm the safety of new designs rather than over-relying on manufacturers to certify their own aircraft.
Lion Air Flight 610 crashed on October 29, 2018, taking 189 lives. Preliminary information from the investigation tells us that in the minutes before the crash, the pilots fought a terrifying battle with the airplane’s Maneuvering Characteristics Augmentation System (MCAS), which repeatedly pushed the nose of the airplane down toward the ocean.
The reason? One of the airplane’s angle of attack sensors fed erroneous information to the MCAS, causing it to “believe” that the nose of the airplane was too high. This then triggered the MCAS to repeatedly push the airplane’s nose down.
The Lion Air investigation quickly identified the MCAS problem and revealed that pilots did not have sufficient information and training about the system. The investigators also shockingly learned that other pilots flying the same airplane the day before had faced a similar MCAS problem, but that those pilots, with the help of an off-duty pilot who happened to be sitting in the cockpit’s jump seat, were able to diagnose the problem and to shut off the MCAS.
The FAA chose not to ground the Boeing 737 Max 8, even though the Lion Air disaster revealed the MCAS problem and that 737 Max pilots were likely not sufficiently trained about the MCAS and how to respond to emergencies that it could potentially cause. As such, airlines all over the world continued to fly the airplane until Ethiopian Airlines Flight 302, another 737 Max 8, crashed on March 10, 2019, taking 157 lives.
Following the March 10 crash, Ethiopian Airlines immediately grounded all of its Boeing 737 Max 8 airplanes and other airlines soon followed suit. On March 11, China and Indonesia ordered the grounding of all 737 Max 8 airplanes.
On March 12, The European Union Aviation Safety Agency grounded all Boeing 737 Max 8 airplanes in Europe. That same day, Boeing CEO Dennis Muilenburg called President Donald Trump to assure him that the 737 Max 8 was safe, and Secretary of Transportation Elaine Chao flew on a 737 Max 8 from Austin, Texas, to Washington, DC, presumably to display her confidence in the airplane’s safety.
That same day – March 12 – acting FAA Administrator Daniel Elwell issued a statement that the FAA had found “no systemic performance issues” and had “no basis” to ground the airplane. The next day, however, Canada grounded the airplane, and later that day Trump announced that the US would ground the Boeing 737 Max 8 and 9 airplanes. The FAA claimed that new information caused the US to finally act, but the similarities between the two disasters were apparent when Flight 302’s flight track was released soon after its crash.
The US followed rather than led the response to the Ethiopian Airlines disaster. It was not our finest hour.
The Federal Aviation Act provides the FAA with the authority to issue regulations in order to establish “minimum standards required in the interest of safety … for the design, material, construction, quality of work, and performance of aircraft …” The FAA must review the designs of aircraft produced in the US and certify that the designs meet the applicable minimum standards.
The FAA has increasingly delegated its duty of certifying aircraft designs to aviation manufacturers. The FAA relies on aviation manufacturers because they have the technical knowledge and experience necessary to understand complex aircraft designs and because the FAA lacks the resources and expertise necessary to conduct the reviews on its own.
In theory, the FAA leverages manufacturer assets and expertise, but still conducts a meaningful review before certifying a new design. In practice, aviation manufacturers, like Boeing, are performing the review process with limited FAA oversight.
The Boeing 737 Max 8 crashes have brought much-needed public attention to the all too cozy relationship between the FAA and the aviation industry. Only days after her flight on a Boeing 737 Max airplane, Secretary Chao requested that her department audit the FAA’s certification of the airplane.
According to CNN, the Justice Department has issued subpoenas to Boeing as part of a criminal probe, although it is unclear at this point what, if any laws, may have been broken. And Congress will hold hearings to investigate the disasters and the FAA’s certification of the Boeing 737 Max airplanes.
Aviation safety should be the paramount concern in the aftermath of the Lion Air and Ethiopian Air tragedies. This means that the FAA must reevaluate
