Study of some Causes of Unavailability of Components and Services and their Effects over the Lifecycle of an Aeronautical Project 2011-36-0279

Life-critical aeronautical projects are increasing their lifecycle up to the point where a product is developed to be available in the market for more than 70 years, but requiring daily service support and replacement parts. Therefore, unavailability of components or services can have a severe impact over the product through its lifecycle. In this work we study some causes of unavailability of components and services and their effects over the lifecycle of an aeronautical project, to propose recommendations, alternatives and actions to be taken in the early phases of project development to help mitigate such effects over the product lifecycle. To do that, we initially present the causes of unavailability of components and services. Then, we discuss some of their effects over the lifecycle of an aeronautical project. Finally, we propose recommendations, alternatives and actions to be taken in the early phases of project development to help mitigate such effects over the product lifecycle, and their sufficiency. This is intended to help in developing future requirements to guarantee that all the objectives of the project are accomplished on time and with no addition on its cost over the product lifecycle.
