This bachelor thesis focused on Development of an Alternative Mean of Compliance (AltMoC) for Inspecting the passenger door stops from Embraer ERJ - 145 aircraft Using Non-Destructive Testing Fluorescent penetrant method. The main goal of this work is to simplify the task with the help of a developed inspection for checking a structural component. A structural component is subject to fatigue and physical stress on it, as well as corrosion. Detailed detection of the smallest damage and metal fatigue. The developed AltMoC is aimed at significantly accelerating work processes, making inspection cheaper as well as having a simplified and clear process using penetrant testing. Having carried out research, the Author, carefully select the appropriate method for inspecting a structural component based on the type of material from which it is made, considering its’ its physical and chemical properties. Develop the correct sequence of actions in the instructions. Thanks to this, the workflow time and the risk of errors occurred due to Employees' misunderstanding significantly reduced.
