With the constant development in the aviation area, it is the search for a greater availability of the aircraft as well as the reduction of costs related to the maintenance that are leading operators and maintenance centers to implement reliability programs. In general, excluding test operations and other specific operations, civil aviation is designed in order to carry transport flights with passengers, mail or specific cargo. While military aviation is designed to carry out aerial combat operations, logistical transport support, surveillance or reconnaissance flights, among others special operations. Thus, civil aviation is aimed for repetitive and systematic air transport and military aviation for punctual and particular operations. The success of the use of Reliability Programs in civil aviation increases the reliability of the aircrafts related to maintenance costs and availability. This success has, step by step, seduced the interest in military aviation. Due to the type of maintenance (MRO) that OGMA is responsible for and in parallel decision with the Operator (costumer), it was agreed to implement a Reliability Program, as a continuous improvement project, with the goal of increasing the reliability of rotable components as well as of the self military cargo aircrafts of the fleet. By this, this MSc Thesis is focused on the validation, implementation and application of an Aircraft Reliability Program, calculation of reliability metrics, generation of alerts, root cause search and failure modes, implementation of a failure mode and analysis related to design and processes as well as corrective actions and their monitoring. Issues such as maintenance data, metrics calculation, alert levels analysis, root causes investigation, corrective actions implementation and monitoring processes are addressed.
