Which term describes the count of modifications made to a specific aircraft design?

• A. Aircraft production series letter
• B. Number of times a aircraft design was modified
• C. Immediate action
• D. Warnings

Answer: (B)

Tracking how many times a design has been changed is about counting the modifications that have been applied to that design. The term that fits this idea describes the number of times the aircraft design was altered, capturing its modification history and evolution over time. This is distinct from a production series letter, which identifies a production block rather than how many changes were made to the design itself; and from immediate action, which is about urgent maintenance tasks, or warnings, which are notices of potential issues. So, counting the modifications directly describes the concept being tested.
