14 CFR Ch. I (1–1–24 Edition) 

§ 25.1 

cookware that is identified for use with the 
cooktop. Restraints must be designed to be 
easily utilized and effective in service. The 
cookware restraint system should also be de-
signed so that it will not be easily disabled, 
thus rendering it unusable. Placarding must 
be installed which prohibits the use of 
cookware that cannot be accommodated by 
the restraint system. 

(c) Placarding must be installed which pro-

hibits the use of cooktops (i.e., power on any 
burner) during taxi, takeoff, and landing. 

(d) Means must be provided to address the 

possibility of a fire occurring on or in the 
immediate vicinity of the cooktop. Two ac-
ceptable means of complying with this re-
quirement are as follows: 

(1) Placarding must be installed that pro-

hibits any burner from being powered when 
the cooktop is unattended. (N

OTE

: This 

would prohibit a single person from cooking 
on the cooktop and intermittently serving 
food to passengers while any burner is pow-
ered.) A fire detector must be installed in the 
vicinity of the cooktop which provides an au-
dible warning in the passenger cabin, and a 
fire extinguisher of appropriate size and ex-
tinguishing agent must be installed in the 
immediate vicinity of the cooktop. Access to 
the extinguisher may not be blocked by a 
fire on or around the cooktop. 

(2) An automatic, thermally activated fire 

suppression system must be installed to ex-
tinguish a fire at the cooktop and imme-
diately adjacent surfaces. The agent used in 
the system must be an approved total flood-
ing agent suitable for use in an occupied 
area. The fire suppression system must have 
a manual override. The automatic activation 
of the fire suppression system must also 
automatically shut off power to the cooktop. 

(e) The surfaces of the galley surrounding 

the cooktop which would be exposed to a fire 
on the cooktop surface or in cookware on the 
cooktop must be constructed of materials 
that comply with the flammability require-
ments of part III of appendix F to part 25. 
This requirement is in addition to the flam-
mability requirements typically required of 
the materials in these galley surfaces. Dur-
ing the selection of these materials, consid-
eration must also be given to ensure that the 
flammability characteristics of the mate-
rials will not be adversely affected by the use 
of cleaning agents and utensils used to re-
move cooking stains. 

(f) The cooktop must be ventilated with a 

system independent of the airplane cabin and 
cargo ventilation system. Procedures and 
time intervals must be established to inspect 
and clean or replace the ventilation system 
to prevent a fire hazard from the accumula-
tion of flammable oils and be included in the 
instructions for continued airworthiness. 
The ventilation system ducting must be pro-
tected by a flame arrestor. [N

sonic Airplanes,’’ dated August 1, 1991.] 

(g) Means must be provided to contain 

spilled foods or fluids in a manner that will 
prevent the creation of a slipping hazard to 
occupants and will not lead to the loss of 
structural strength due to airplane corro-
sion. 

(h) Cooktop installations must provide 

adequate space for the user to immediately 
escape a hazardous cooktop condition. 

(i) A means to shut off power to the 

cooktop must be provided at the galley con-
taining the cooktop and in the cockpit. If ad-
ditional switches are introduced in the cock-
pit, revisions to smoke or fire emergency 
procedures of the AFM will be required. 

(j) If the cooktop is required to have a lid 

to enclose the cooktop there must be a 
means to automatically shut off power to 
the cooktop when the lid is closed. 

15. 

Hand-Held Fire Extinguishers. 

(a) For airplanes that were originally type 

certificated with more than 60 passengers, 
the number of hand-held fire extinguishers 
must be the greater of— 

(1) That provided in accordance with the 

requirements of § 25.851, or 

(2) A number equal to the number of origi-

nally type certificated exit pairs, regardless 
of whether the exits are deactivated for the 
proposed configuration. 

(b) Extinguishers must be evenly distrib-

uted throughout the cabin. These extin-
guishers are in addition to those required by 
paragraph 14 of this SFAR, unless it can be 
shown that the cooktop was installed in the 
immediate vicinity of the original exits. 

16. 

Security. The requirements of § 25.795 are 

not applicable to airplanes approved in ac-
cordance with this SFAR.

Subpart A—General 

§ 25.1

Applicability. 

(a) This part prescribes airworthiness 

standards for the issue of type certifi-
cates, and changes to those certifi-
cates, for transport category airplanes. 

(b) Each person who applies under 

Part 21 for such a certificate or change 
must show compliance with the appli-
cable requirements in this part.
