Boeing Accused Of Hiding 737 MAX Flaws

Boeing is being accused of hiding flaws in its 737 MAX by LOT Polish Airlines after two fatal accidents killed 300+ people amid a decade worth of turbulence for customers, passengers and the planemaker.

The European carrier is in a Seattle Federal Court, arguing that the 737 MAX, which has encountered many safety flaws since its conception, had these flaws deliberately concealed by Boeing to secure sales in its bid to compete with Airbus and its A320neo.

Attorneys laid out the findings during a hearing on 11 May 2026, at which the business claimed that, during key decisions by LOT to move forward with new planes in 2016, Boeing effectively misrepresented the safety of the aircraft it proposed.

A Long Battle Between Boeing and LOT

LOT first filed this suit in October 2021, where it sought hundreds of millions of damages for the losses that it encountered during a nearly 2-year global grounding of the 737 MAX following the fatal accidents of a Lion Air MAX in 2018 and Ethiopian Airlines MAX in early 2019, killing a total of 346 people.

The business wasn’t the only airline to clap back at Boeing with frustrations over how the situation from sale to delivery and grounding had been handled. In the case of LOT, it was alleged that Boeing hid the MCAS software’s single-sensor design from the airline and, as a result, misrepresented its safety.

This vulnerable part of the 737 MAX, introduced as part of Boeing’s efforts to race the MAX to entry into service amid rising pressure from Airbus, which had advanced more rapidly with its A320neo. As a result, certain areas that would’ve seen higher regulatory scrutiny and delayed the debut were hidden.

Ultimately, the decision was made to hide key safety features to get the MAX airborne as quickly as possible and avoid losing valuable market share and lucrative contracts to competitors. This led LOT to feel misled into choosing the MAX over something like the A320neo.

LOT Polish Hurts From The Deception

For LOT Polish, the grounding of the 737 MAX following the accidents led to route cancellations and forced wet-leases, further compounding cost pressures amid the emerging COVID-19 pandemic. This all culminated in revenue dipping and pressure points growing stronger by the week.

LOT’s attorney has more specifically portrayed Boeing’s sales pitch as painting the 737 MAX, despite its efficiency upgrades, as essentially the same as the 737NG, the previous-generation member of the single-aisle family that the MAX was built to replace effectively.

However, in those sales pushes, Boeing omitted the risks associated with MCAS and the fundamental simulator needs, which locked LOT into leases it wouldn’t have signed had it known the full picture. Then, when groundings hit, the pain was amplified tenfold by competitor gains, an imbalance in the fleet, and more.

Other Airlines Also Push Boeing Over 737 MAX

A pursuit for responsibility and damages doesn’t see LOT positioned on its own. Before 2021, several other airlines also sued Boeing for damages and misrepresentation regarding the 737 MAX, including Alaska Airlines and Southwest.

Global carriers also looked to do something similar, and if it weren’t for the impact of the grounding, it would have been the FAA certification programme for the 737-7 and 737-10. These two uncertified models have been delayed for years, and left airlines without the planes they committed to, causing further financial burden.

LOT’s later approach to this has drawn some skepticism that such a ruling will get over the line in the manner the Polish carrier would want. However, it’s representative of an era where Boeing went so horribly wrong, on its people, flyers and especially airline customers, something it’s still recovering from to this day.
