Avionics material that is either repairable, flight critical, procured from a commercial source of supply, or has a unit cost of $800 or more is which type material?

• A. Type 1
• B. Type 6
• C. Type 7
• D. Type 4

Answer: (D)

The main idea here is how avionics material is categorized for inventory and maintenance purposes. Type 4 is the category used for items that require special handling because they are repairable, flight critical, procured from a commercial source, or have a relatively high unit cost (in this case, $800 or more). Grouping these items as Type 4 signals the logistics system to treat them with emphasis on repairability, supplier options, and cost impact, since they may need special repair processes, warranties, or oversight compared to lower-cost or non-repairable items. Other types exist for items that don’t meet these criteria—typically items that are non-repairable, not flight critical, or have lower costs—so they don’t fall into the same handling category.
