The recent airlines crashes – Ethiopian Airlines and Lion Air, both with Boeing 737 Max 8 jet – lead to the fact that there are some loopholes in the safety standards followed by the aerospace industry that operates with the strict guidelines and accurate specifications by using the most advanced technologies and precise manufacturing processes. It is the responsibility of an aircraft manufacturer and the maker of each and every aircraft part in it to ensure that the airplane, all of the aircraft parts and the software associated with it are made without any design or manufacturing defect.
According to the preliminary investigation reports, the reason for the crash was the automated flight-control system called the MCAS (Maneuvering Characteristics Augmentation System), which adjusts the trim to try to avoid an imminent stall. Moreover, in this case, it seems that pilots were not given the enough information/training about the new system on the plane.
