Which document would be consulted as the primary reference for M-31 operations?

• A. NAVAIR 51-5FAA-1
• B. NAVAIR 51-3FAA-1
• C. NAVAIR 51-4FAA-1
• D. NAVAIR 51-5FAA-4

Answer: (D)

In Navy technical documentation, the primary reference for operating a system is the most current official manual that covers its procedures. For the M-31, the official operations guidance is found in the NAVAIR 51-5FAA-4 manual—the fourth revision in the 51-5FAA family. The higher revision number indicates the latest updates to procedures, warnings, and step-by-step operations. Earlier revisions (like -1 or -3) are older and may not reflect the current practices or safety requirements, or they may cover related areas that aren’t the primary source for day-to-day operations. So, for authoritative, up-to-date operational instructions, you consult NAVAIR 51-5FAA-4.
