FAR 23.2330 — Fire Zone Protection
FAR 23.2330 covers fire protection requirements in designated fire zones: flight structures, engine mounts, electrical cables, and emergency equipment.
FAR 23.2330 establishes fire protection standards for parts of a Part 23 airplane located in or near designated fire zones — areas where a fire is most likely to occur, such as around the engine.
The rule requires that:
- Flight controls, engine mounts, and other flight structures within or adjacent to designated fire zones must be able to withstand the effects of a fire, so the airplane remains controllable long enough to land.
- Engines located in a designated fire zone must remain attached to the airplane if a fire occurs — the mounts can't burn through and let the engine separate.
- Any terminals, equipment, and electrical cables used during emergency procedures in a fire zone must be fire-resistant, so emergency systems (like fuel shutoffs or extinguishers) keep working during a fire.
Operationally, this matters because it gives pilots a fighting chance: the structure stays intact, the engine stays put, and emergency electrical paths still function while you run the engine fire checklist and divert.
