LOT Polish Airlines Accuses Boeing of Concealing 737 MAX Safety Issues to Boost Sales

• LOT alleges Boeing hid the MCAS flight-control system and its safety issues to avoid expensive simulator training requirements that would have hurt MAX sales competitiveness against Airbus A320 jets
• The MCAS system played a major role in two crashes (Lion Air in October 2018 and Ethiopian Airlines in March 2019) that killed 346 people and led to a 20-month global grounding of the 737 MAX
• Boeing counters that LOT's fraud claims lack credibility since the airline continues to operate 737 MAX aircraft daily after regulators approved design changes and additional pilot training

LOT Polish Airlines Accuses Boeing of Concealing 737 MAX Safety Issues

LOT Polish Airlines is taking Boeing to trial in U.S. District Court in Seattle, alleging the aerospace manufacturer deliberately concealed safety problems with the 737 MAX during a 2016 sales campaign. The Polish flag carrier claims Boeing hid issues to secure orders while the airline was recovering from financial difficulties.

Key Allegations:

LOT's attorney argues Boeing concealed the Maneuvering Characteristics Augmentation System (MCAS)—a flight-control software designed to counter the aircraft's tendency to pitch up—to avoid requiring extensive pilot simulator training. Such training would have increased costs and hurt Boeing's competitiveness against Airbus's A320 family. LOT committed to leasing 15 MAX jets based on Boeing's promise of minimal training requirements.

The Crashes:

MCAS malfunctioned in two fatal crashes—Lion Air in October 2018 and Ethiopian Airlines Flight 302 in March 2019—killing 346 people combined. Regulators grounded the MAX worldwide in 2019 for 20 months until design changes and additional pilot training were implemented.

Legal Battle:

LOT, which sued Boeing in 2021, seeks damages for revenue losses during the grounding period. The airline is the first to take Boeing to trial over MAX-related claims. Boeing counters that LOT continues operating the MAX daily, questioning the legitimacy of fraud allegations.

Financial Impact:

Boeing has already paid billions to crash victims' families and undisclosed sums to airlines in out-of-court settlements related to the MAX grounding.

The trial centers on whether Boeing intentionally misrepresented the aircraft's safety profile to maintain its competitive edge in the narrowbody jet market.
