CS-VLA 1183 Lines, fittings and components
ED Decision 2003/18/RM
(a) Except as provided in sub-paragraph (b) of this paragraph, each component, line, and fitting carrying flammable fluids, gas, or air in any area subject to engine fire conditions must be at least fire resistant, except that flammable fluid tanks and supports which are part of and attached to the engine must be fireproof or be enclosed by a fireproof shield unless damage by fire to any non-fireproof part will not cause leakage or spillage of flammable fluid. Components must be shielded or located so as to safeguard against the ignition of leaking flammable fluid. Flexible hose assemblies (hose and end fittings) must be approved. However, if the total capacity of the oil system, including tanks, lines and sumps is less than 5 litres, the components of this system need only be fire resistant.
(b) Sub-paragraph (a) of this paragraph does not apply to -
(1) Lines, fittings, and components which are already approved as part of a type certificated engine; and
(2) Vent and drain lines, and their fittings whose failure will not result in, or add to, a fire hazard.
