14 C.F.R. §§ 29.1195–29.1203

5 sections in range

§29.1195. Fire extinguishing systems.

14 C.F.R. § 29.1195

(a)
Each turbine engine powered rotorcraft and Category A reciprocating engine powered rotorcraft, and each Category B reciprocating engine powered rotorcraft with engines of more than 1,500 cubic inches must have a fire extinguishing system for the designated fire zones. The fire extinguishing system for a powerplant must be able to simultaneously protect all zones of the powerplant compartment for which protection is provided.
(b)
For multiengine powered rotorcraft, the fire extinguishing system, the quantity of extinguishing agent, and the rate of discharge must—
(1)
For each auxiliary power unit and combustion equipment, provide at least one adequate discharge; and
(2)
For each other designated fire zone, provide two adequate discharges.
(c)
For single engine rotorcraft, the quantity of extinguishing agent and the rate of discharge must provide at least one adequate discharge for the engine compartment.
(d)
It must be shown by either actual or simulated flight tests that under critical airflow conditions in flight the discharge of the extinguishing agent in each designated fire zone will provide an agent concentration capable of extinguishing fires in that zone and of minimizing the probability of reignition.

§29.1197. Fire extinguishing agents.

14 C.F.R. § 29.1197

(a)
Fire extinguishing agents must—
(1)
Be capable of extinguishing flames emanating from any burning of fluids or other combustible materials in the area protected by the fire extinguishing system; and
(2)
Have thermal stability over the temperature range likely to be experienced in the compartment in which they are stored.
(b)
If any toxic extinguishing agent is used, it must be shown by test that entry of harmful concentrations of fluid or fluid vapors into any personnel compartment (due to leakage during normal operation of the rotorcraft, or discharge on the ground or in flight) is prevented, even though a defect may exist in the extinguishing system.

§29.1199. Extinguishing agent containers.

14 C.F.R. § 29.1199

(a)
Each extinguishing agent container must have a pressure relief to prevent bursting of the container by excessive internal pressures.
(b)
The discharge end of each discharge line from a pressure relief connection must be located so that discharge of the fire extinguishing agent would not damage the rotorcraft. The line must also be located or protected to prevent clogging caused by ice or other foreign matter.
(c)
There must be a means for each fire extinguishing agent container to indicate that the container has discharged or that the charging pressure is below the established minimum necessary for proper functioning.
(d)
The temperature of each container must be maintained, under intended operating conditions, to prevent the pressure in the container from—
(1)
Falling below that necessary to provide an adequate rate of discharge; or
(2)
Rising high enough to cause premature discharge.

§29.1201. Fire extinguishing system materials.

14 C.F.R. § 29.1201

(a)
No materials in any fire extinguishing system may react chemically with any extinguishing agent so as to create a hazard.
(b)
Each system component in an engine compartment must be fireproof.

§29.1203. Fire detector systems.

14 C.F.R. § 29.1203

(a)
For each turbine engine powered rotorcraft and Category A reciprocating engine powered rotorcraft, and for each Category B reciprocating engine powered rotorcraft with engines of more than 900 cubic inches displacement, there must be approved, quick-acting fire detectors in designated fire zones and in the combustor, turbine, and tailpipe sections of turbine installations (whether or not such sections are designated fire zones) in numbers and locations ensuring prompt detection of fire in those zones.
(b)
Each fire detector must be constructed and installed to withstand any vibration, inertia, and other loads to which it would be subjected in operation.
(c)
No fire detector may be affected by any oil, water, other fluids, or fumes that might be present.
(d)
There must be means to allow crewmembers to check, in flight, the functioning of each fire detector system electrical circuit.
(e)
The writing and other components of each fire detector system in an engine compartment must be at least fire resistant.
(f)
No fire detector system component for any fire zone may pass through another fire zone, unless—
(1)
It is protected against the possibility of false warnings resulting from fires in zones through which it passes; or
(2)
The zones involved are simultaneously protected by the same detector and extinguishing systems.
