Select the publication that serves as the primary reference for M-31 procedures.

• A. NAVAIR 51-5FAA-1
• B. NAVAIR 51-5FAA-3
• C. NAVAIR 51-5FAA-2
• D. NAVAIR 52-5FAA-1

Answer: (C)

The main idea is knowing where the official, definitive procedures come from. For M-31 procedures, the designated primary reference is NAVAIR 51-5FAA-2. This volume is the official source that contains the complete, up-to-date M-31 procedures, including the step-by-step instructions, safety notes, and required references you need when performing tasks. The other volumes in the 51-5FAA set are supplementary or cover different aspects or earlier editions; they don’t serve as the primary source for executing M-31 procedures. A different publication number, like 52-5FAA-1, is from another series and doesn’t cover M-31 procedures, so it isn’t the primary reference for this topic.
