The development of civil aviation in the world makes it possible to meet the needs of the civilian population in comfortable conditions of movement over long distances with minimal time spent in comparison with other types of transport. But it is worth realizing that in the pursuit of a low cost, which would allow attracting a large number of both new and regular customers, and a low cost of organizing such transportation, which is of interest above all to companies seeking to develop in the aviation sector, the safety and comfort of customers should not be neglected . After all, the blind pursuit of the opportunity to increase one's fortunes eventually leads to terrible disasters with a large number of human victims. At the same time, companies bear correspondingly terrible losses. In order to increase the level of flight safety, international organizations have been created that have undertaken the implementation of the issue of regulation, standardization of the conditions for servicing the fleet of aircraft, rules for flight operations, requirements for the safety and reliability of both new and already manufactured aircraft, as well as supervision of compliance with these rules by all companies engaged in commerce in the field of aviation and the manufacture of aviation equipment. In turn, the companies undertake to provide complete information, which is necessary to increase the safety of flights and the reliability of aviation equipment. But one way or another, various factors lead to the occurrence of various incidents and disasters. That is why aviation designers, when developing new types of aviation equipment, lay down new engineering solutions, solve a number of certain problems, which in turn will increase the reliability and safety of the operation of the aviation fleet of equipment. In addition, designers and engineers are engaged in the modernization of elements and systems of already existing aircraft. 15 The purpose of this diploma project is to analyze the design of the fuel system of the An-70 aircraft in order to identify factors that affect the probability of a fire occurring in the fuel tanks-caissons of four-engine turboprop cargo aircraft and to carry out the necessary modernization of the identified weak points of the fuel system in order to increase the operational reliability of the system, and flight safety in general.
