The qualitative focus group research utilizes the theory of constraints and supply chain management (SCM) framework to review over 179 emails discoveries in obsolescence issues surrounding the Chinook/Cargo Helicopter-47 Delta-Model (CH-47 D-Model) helicopter. In the early part of 2010, there were 66 vendors who manufactured long-lead D-Model parts; now, only 13 remain. As foreign military sale (FMS) customers upgrade to more advanced systems, a critical challenge focuses on customer-centric, predictive business models, and smart automation to understand the value of military and defense operations for legacy systems. The researchers utilized participant data from focus group discussions, emails, and written correspondence to develop a comprehensive spotlight into the Chinook/Cargo community within FMS. The purpose is to determine if there is value in servicing country needs for CH-47 D-Model parts. Shortages of critical components and a lack of access to authentic, certified spare parts affect the safety and performance of the helicopters.
