Boeing 737 Max Dutch roll - 10 things to know with detail

• Dutch roll is a phenomenon that occurs in aircraft when there is an oscillatory motion of the aircraft around its longitudinal and lateral axes simultaneously.
• The Boeing 737 Max experienced issues with Dutch roll during flight testing and in some reported incidents prior to the grounding of the aircraft in 2019.
• Dutch roll in the Boeing 737 Max was primarily caused by a combination of the aircraft's aerodynamic characteristics, including its wing design and flight control system.
• The wing design of the Boeing 737 Max, specifically its larger and more efficient wings, contributed to the aircraft's susceptibility to Dutch roll.
• The flight control system of the Boeing 737 Max, specifically the Maneuvering Characteristics Augmentation System (MCAS), exacerbated Dutch roll issues by automatically adjusting the aircraft's trim to counteract the effects of stall.
• The combination of the aerodynamic characteristics and flight control system of the Boeing 737 Max led to instances where the aircraft would enter into a Dutch roll during flight, causing discomfort for passengers and potentially compromising the safety of the flight.
• Boeing implemented software updates to the MCAS system in an effort to address Dutch roll issues in the Boeing 737 Max and improve the overall safety of the aircraft.
• Despite these updates, Dutch roll was a contributing factor in the two fatal crashes involving the Boeing 737 Max in 2018 and 2019, leading to the worldwide grounding of the aircraft.
• The grounding of the Boeing 737 Max allowed for further investigation into the causes of Dutch roll in the aircraft and prompted additional safety measures to be implemented before the aircraft could return to service.
• As of 2021, the Boeing 737 Max has been recertified by aviation authorities and has returned to service with additional safety features and training requirements to address Dutch roll and other potential issues.
