Abstract

In this article, the reliability of the equipment related to the PC-7 aircrew is evaluated using the FMEA method. For this purpose, a complete review of the equipment and systems related to the PC-7 aircrew was done. Then, the potential failure modes were determined for each of the subsystems. In the following, the parameters of the RPN formula were determined by the questionnaire method and obtaining the opinions of technical experts and pilots of the PC-7 aircraft about the severity of the failure, the probability of their occurrence, and the difficulty of detecting them. Also, the risk diagram was drawn based on two main parameters, including the severity of the effect and the probability of failure. Finally, the highest RPN coefficient determined that the three electronic, engine, and airplane fuel systems have the highest RPN values and risk probability.
