Abstract
The article discusses the legal consequences of the two aviation accidents involving B737 MAX aircraft in which a total of 346 people were killed. Most probably, in both crashes, one of the MCAS sensors was defective and transmitted false information to the control module, which continuously pushed down the nose of the airplane. The article aims to indicate the entities liable for damage caused by the accidents, in particular the liability for passengers’ death, the destruction of airplanes and aircraft grounding.
