Twenty-two elements and fourteen skills. Three of the skills — troubleshooting detection and extinguishing, and press-to-test — you perform in the shop on the airframe systems trainer, shared with AF-M. The rest are imagery and one lookup.

Chapter and section verified against FAA-H-8083-32B, 2023 edition, on 28 August 2026. Page numbers are deliberately not cited: they move between printings, and a citation that rots silently is worse than a coarser one that stays true. Checked by our handbook citation check against our index of the handbook's chapters and sections.
