The 2008 crash of a jet named Quantus went into a sudden nosedive due to a computer system failure. There are some injured crew members and passengers before the pilot regains control within seconds. The main reason behind the event is a software failure and the system quickly enters the normal state. Technical conditions and ethical decisions do not affect people's lives. They should take place more programmatically and efficiently enough so that such events do not happen again in the future. If an accident had occurred at that moment and the system had not been able to find the fault in the computer system, everyone, and especially the manufacturer, would have thought that the plane had been destroyed by pilot error. There is another condition on using the software system and the pilot also cannot make any changes to the software system. The control system should be made more sensitive and able to react instantly to the quality of the input. There is also the possibility that the manufacturer always assumes that the aircraft's software and data are always correct. Software engineers often worry about setting up software efficiently and accurately so that accidents never occur due to technological failures. The point depicted by software engineers considers a decisive action based on the principles of the code. Software engineers consider state boundaries, try to solve and understand requirements, using the skills to design them appropriately and execute them correctly. The subsequent investigation concludes that human error is also responsible for the Quantus crash. Investigators have been trying to find the possible factor and said it is unclear how to add the data manually. If the software… is at the center of the card… it is priority and to make it absolutely correct, the cost may be higher, but you focus on happiness and it may include exceptional situations. It may take a long time to improve the software and efforts and there are some critics of this theory. Because sometimes it is necessary to focus on moral values ​​and actions, or on the results and motivation of the action. The theory of utilitarianism describes or explains public safety first as the Quantus Jet accident has been fully verified based on the same and the manufacturer must take care of the fault that occurred and it will be repaired with all efforts and works in a manner accurate. The conclusion is that these two theories use moral values ​​on actions or on the results of actions. Therefore, using these theories, the analysis of our event is operational and exploits the advantages of the theories addressed.
