Which TO provides inspection intervals for the A-10 aircraft?

• A. TO 1A-10C-3
• B. TO 1A-10C-9
• C. TO 1A-10C-1
• D. TO 1A-10C-6

Answer: (D)

Knowing how Technical Orders are organized helps you locate the exact information you need. For the A-10, the TOs in the 1A-10C series cover different kinds of maintenance data, each volume focusing on a particular topic. The volume that contains inspection intervals is the maintenance schedules volume. It lists when inspections are due—daily checks, hourly/maintenance-hour based intervals, and other scheduled tasks—so crews can plan and execute maintenance on time.

The other volumes in the same series focus on different subjects, such as procedures, troubleshooting, or other maintenance data, and do not provide the official inspection intervals. So when you need to know how often inspections must be performed, the maintenance-schedules volume is the authoritative source.
