Boeing sells 200 of its 737 MAX planes to International Airlines Group, the first sale of the controversial airliners since two fatal crashes and subsequent worldwide groundings earlier this year.
A former Boeing chief test pilot is indicted by a United States grand jury for deceiving the Federal Aviation Administration during the certification process for the Boeing 737 MAX aircraft, which resulted in two fatal crashes and a subsequent grounding of the aircraft.
Boeing agrees to pay US$2.5 billion to settle criminal charges claiming that it covered-up design flaws in its Boeing 737 MAX passenger planes from safety officials. The U.S. Department of Justice says that the firm chose "profit over candour".
The U.S. Federal Aviation Administration clears Boeing's 737 MAX to fly again, provided that all planes receive modifications to their software and wiring and that all pilots receive additional training.
A United States House Committee on Transportation and Infrastructure report blames a "horrific culmination of a series of faulty technical assumptions by Boeing's engineers, a lack of transparency on the part of Boeing's management, and grossly insufficient oversight" by the Federal Aviation Administration for two deadly Boeing 737 MAX crashes, resulting in the airliner being grounded worldwide.
Russian aircraft leasing firm Avia Capital Services, which has ordered 35 Boeing 737 MAX aircraft, sues Boeing in an Illinois court in the first legal action taken by a 737 MAX customer in the wake of the groundings. Avia seek damages and a cancellation of the order, claiming Boeing were fraudulent, breached their contract with Avia, and negligently introduced design flaws to the aircraft and made negligent representations to the Federal Aviation Authority seeking the plane's certification. With nearly 400 jets grounded worldwide since March, lawyers representing Avia say they are discussing the possibility of joining the litigation with other companies.
