If EI or QDR disposition instructions for defective material are NOT received within 30 days, which activity is responsible for submitting a request to the CFA?

The correct choice is the Supporting ASD. In Navy logistics, the Supporting Activity Supply Department (ASD) plays a crucial role in managing and overseeing the flow of materials, including defective items, within the supply chain. When disposition instructions for defective materials—such as Equipment Improvement (EI) or Quality Deficiency Report (QDR) instructions—are not received within the specified 30-day timeframe, it becomes the responsibility of the Supporting ASD to submit a request to the Centralized Functional Activity (CFA). This ensures that the process for handling defective materials continues efficiently and that any necessary actions are taken promptly to manage inventory and mitigate potential impacts on operations.

Other departments, like the Main Supply Office or Material Control, may have different responsibilities related to supply management but are not specifically tasked with submitting requests to the CFA in this scenario. Aircraft Division has specialized roles related to aviation assets, but this particular function falls under the purview of the Supporting ASD.
