Inadequate spare parts stock or inventory leads to wind tunnel facilities unavailability and loss of revenue if the wind tunnel subsystem or equipment fails and cannot be repaired or replaced immediately. At the point when the extra part is required however missing in stock, it must be requested from a provider. This causes the operational downtime relying upon the lead time of the extra part. On the other hand, inventory management which handling, controlling and storage of the spare parts is a cost driver for wind tunnel facilities in operating and maintaining wind tunnels. During wind tunnel breakdowns, maintenance personnel spent too much time trying to find and procure spare parts.  Requisition amount depends on gut feel and past experiences, with some casual conference with the maintenance technicians and specialists. Although the number of studies have been conducted in the past two decades to address this issues, therefore the aim of this paper is to theoretically assess the theoretical assessment framework of inventory Management System in wind tunnels and the results of the critical analysis of the current literature clearly demonstrates that there are flaws in the current body of knowledge related to the effectiveness of inventory management in the aerospace industry, especially in wind tunnel facilities and also few of those studies concentrated on spare parts inventory management.
