Abstract. In the aviation industry, maintenance (MRO) is a critical process because it directly affects the safety, reliability, and cost-effectiveness of aircraft operations. Maintenance programs help to keep aircraft in serviceable condition, identify potential malfunctions before they occur, and optimize operating costs. This paper focuses on approaches to improve aircraft MRO performance, with emphasis on the maintenance program and reliability program, as well as opportunities to adapt procedures based on operator experience.

Keywords: aircraft maintenance program, reliability program, efficiency improvement, optimization, statistical methods in maintenance.
