What manual covers static grounding and bonding?

• A. USAF TO 00-25-172 STATIC GROUNDING AND BONDING
• B. NAVY TO 00-25-172 STATIC GROUNDING AND BONDING
• C. MIL-HDBK-5
• D. FAA AC 43-13

Answer: (A)

Grounding and bonding procedures are defined by service-specific manuals, so the direct reference for this topic is the USAF Technical Order dedicated to it. The USAF TO 00-25-172 Static Grounding and Bonding is the authoritative guide used by Air Force maintenance personnel to perform proper grounding during servicing, testing, and fueling, ensuring a reliable bond to prevent static discharge.

The other options aren’t the standard reference for this USAF topic: a Navy equivalent might exist but would be a different manual, MIL-HDBK-5 isn’t a focused grounding reference, and FAA AC 43-13 covers general airframe maintenance practices rather than a dedicated static grounding and bonding manual.
