Which publication number addresses aircraft cleaning and corrosion control?

• A. TM 1-500-344-23-2
• B. TM 1-500-203-23-2
• C. TM 1-500-344-23-1
• D. TM 1-200-344-23-2

Answer: (A)

Publication codes organize topics so you can locate the right manual quickly. The base number 1-500-344 groups together the aircraft maintenance topics, and the subchapter 23-2 specifically designates cleaning and corrosion control. That combination uniquely points to the publication that covers those topics. The other options either use a different base topic (which points to a different subject area) or use a different subchapter within the same base topic, so they don’t address aircraft cleaning and corrosion control. Therefore, TM 1-500-344-23-2 is the correct publication.
