Background 

On January 12, 2010, Fokker Services 

B.V. applied for a supplemental type 

certificate for an interior conversion on 

an Airbus Model A318–112 airplane, 

serial number 3238. The Airbus Model 

A318–112 airplane is a large, transportcategory airplane powered by two 

CFM56–5B9/P engines, with a basic 

maximum takeoff weight of 130,071 

pounds. 

Fokker Services B.V. is requesting 

certification to convert this Airbus 

Model A318–112 to a corporate jet, 

operating for both public and private 

use (not for hire, not for common 

carriage). For private use the aircraft 

will be certified for a maximum of 8 

crew and 23 passengers, and the public 

use occupancy will be a maximum of 8 

crew and 19 passengers. The aircraft 

will be subdivided into an entrance 

way, executive lounge, two private 

lounges, and a private bathroom. The 

entry will include the installation of two 

wet galleys. One of the galleys will 

include the installation of two 

combined cooktop pan units. The 

addition of a cooktop to this interior 

conversion can lead to hazards to both 

occupants and the aircraft. Special 

consideration is needed to address the 

safety standards associated with this 

installation. 

Type Certification Basis 

Under the provisions of Title 14, Code 

of Federal Regulations (14 CFR) 21.101 

Fokker Services B.V. must show that the 

Airbus Model A318–112 airplane, as 

changed, continues to meet the 

applicable provisions of the regulations 

incorporated by reference in Type 

Certificate No. A28NM or the applicable 

regulations in effect on the date of 

application for the change. The 

regulations incorporated by reference in 

the type certificate are commonly 

referred to as the ‘‘original type 

certification basis.’’ The regulations 

incorporated by reference in A28NM are 

14 CFR part 25, as amended by 

Amendments 25–1 through 25–56, with 

reversions to earlier amendments, 

voluntary compliance to later 

amendments, special conditions, 

equivalent safety findings, and 

exemptions listed in the type certificate 

data sheet. 

If the Administrator finds that the 

applicable airworthiness regulations 

(i.e., 14 CFR part 25) do not contain 

adequate or appropriate safety standards 

for the Airbus Model A318–112 airplane 

because of a novel or unusual design 

feature, special conditions are 

prescribed under the provisions of 

§ 21.16. 

Special conditions are initially 

applicable to the model for which they 

are issued. Should the applicant apply 

for a supplemental type certificate to 

modify any other model included on the 

same type certificate to incorporate the 

same or similar novel or unusual design 

feature, the special conditions would 


srobinson on DSK4SPTVN1PROD with PROPOSALS
Federal Register / Vol. 77, No. 167 / Tuesday, August 28, 2012 / Proposed Rules 51945 

also apply to the other model under 

§ 21.101. 

In addition to the applicable 

airworthiness regulations and special 

conditions, the Airbus Model A318–112 

must comply with the fuel vent and 

exhaust emission requirements of 14 

CFR part 34 and the noise certification 

requirements of 14 CFR part 36. 

The FAA issues special conditions, as 

defined in 14 CFR 11.19, in accordance 

with § 11.38, and they become part of 

the type-certification basis under 

§ 21.101. 

Novel or Unusual Design Features 

The Airbus Model A318–112 airplane, 

serial number 3238, will incorporate the 

following novel or unusual design 

feature: Cooktops in the passenger 

cabin. Cooktops introduce high heat, 

smoke, and the possibility of fire into 

the passenger cabin environment. The 

current airworthiness standards of part 

25 do not contain adequate or 

appropriate safety standards to protect 

the airplane and its occupants from 

these potential hazards. The applicant’s 

proposed system is considered to be a 

novel or unusual design feature. 

Discussion 

Currently, ovens are the prevailing 

means of heating food on airplanes. 

Ovens are characterized by an enclosure 

that contains both the heat source and 

the food being heated. The hazards 

presented by ovens are thus inherently 

limited and are well understood through 

years of service experience. Cooktops, 

on the other hand, are characterized by 

exposed heat sources and the presence 

of relatively unrestrained hot cookware 

and heated food. These may represent 

unprecedented hazards to both 

occupants and the airplane. 

Cooktops could have serious 

passenger and aircraft safety 

implications if appropriate requirements 

are not established for their installation 

and use. The requirements identified in 

these proposed special conditions are in 

addition to those considerations 

identified in Advisory Circular (AC) 20– 

168, Certification Guidance for 

Installation of Non-Essential, NonRequired Aircraft Cabin Systems and 

Equipment (CS&E), and those in AC 25– 

17A, Transport Airplane Cabin Interiors 

Crashworthiness Handbook. The intent 

of these proposed special conditions is 

to provide a level of safety that is 

consistent with that on similar aircraft 

without cooktops. 

In similar cooktop installations, the 

FAA has required a deployable cover 

and a means to automatically shut off 

the power when the cover was in use. 

In lieu of these requirements, the 

cooktop installation in this Airbus 

A318–112 will have a lid and a timer 

that is not covered by the lid. The timer 

switches the heating elements on and 

off, has a maximum time of 20 minutes, 

and is still accessible when the lid is 

closed. The cabin crew will be 

instructed on its use. In addition to the 

lid and timer, the applicant will supply 

a fire blanket that is 1,100 by 1,100 mm 

(catalogue no. SAP–967–T). The fire 

blanket meets the requirements of 

British Standard BS 6575:1965. These 

specifications contain the requirements 

for flexibility, heat, electrical resistance, 

and fire extinguishing including 

cooking oil fires for light duty and 

heavy duty (industrial) applications. 

For this cooktop installation, the FAA 

requires evidence that with the cooktop 

lid closed, the temperature set on 

‘‘high,’’ and the timer at maximum, the 

cooktop will maintain safe operation 

and will not create a hazardous 

condition even with cooking oil in the 

cooktop. 

Applicability 

As discussed above, these special 

conditions are applicable to the Airbus 

Model A318–112. Should Fokker 

Services B.V. apply at a later date for a 

supplemental type certificate to modify 

any other model included on Type 

Certificate No. A28NM to incorporate 

the same novel or unusual design 

feature, the special conditions would 

apply to that model as well. 

Conclusion 

This action affects only certain novel 

or unusual design features on one model 

of airplane. It is not a rule of general 

applicability and affects only the 

applicant who applied to the FAA for 

approval of these features on the 

airplane. 

List of Subjects in 14 CFR Part 25 

Aircraft, Aviation safety, Reporting 

and recordkeeping requirements. 

The authority citation for these 

special conditions is as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701, 

44702, 44704. 

The Proposed Special Conditions 

Accordingly, the Federal Aviation 

Administration (FAA) proposes the 

following special conditions as part of 

the type certification basis for the 

Airbus Model A318–112 airplane, serial 

number 3238, modified by Fokker 

Services B.V. 

Cooktop installations with electrically 

powered burners must comply with the 

following criteria: 

1. Means, such as conspicuous 

burner-on indicators, physical barriers, 

or handholds, must be installed to 

minimize the potential for inadvertent 

personnel contact with hot surfaces of 

both the cooktop and cookware. 

Conditions of turbulence must be 

considered. 

2. Sufficient design means must be 

included to restrain cookware while in 

place on the cooktop, as well as 

representative contents, e.g., soup, 

sauces, etc., from the effects of flight 

loads and turbulence. Restraints must be 

provided to preclude hazardous 

movement of cookware and contents. 

These restraints must accommodate any 

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 designed 

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. 

3. Placarding must be installed that 

prohibits the use of cooktops (i.e., 

power on any burner) during taxi, 

takeoff, and landing. 

4. Means must be provided to address 

the possibility of a fire occurring on or 

in the immediate vicinity of the 

cooktop. Two acceptable means of 

complying with this requirement are as 

follows: 

a. Placarding must be installed that 

prohibits any burner from being 

powered when the cooktop is 

unattended, which would prohibit a 

single person from cooking on the 

cooktop and intermittently serving food 

to passengers while any burner is 

powered; a fire detector must be 

installed in the vicinity of the cooktop 

that provides an audible warning in the 

passenger cabin; and a fire extinguisher 

of appropriate size and extinguishing 

agent must be installed in the 

immediate vicinity of the cooktop. 

Access to the extinguisher must not be 

blocked by a fire on or around the 

cooktop. One of the fire extinguishers 

required by § 25.851 may be used to 

satisfy this requirement. If this is not 

possible, then the extinguisher in the 

galley area would be additional; or, 

b. An automatic, thermally activated, 

fire-suppression system must be 

installed to extinguish a fire at the 

cooktop and immediately adjacent 

surfaces. The agent used in the system 

must be an approved, total-flooding 

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.

5. 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 

requirements of 14 CFR part 25, 

appendix F, part III. This requirement is 

in addition to the flammability 

requirements typically required of the 

materials in these galley surfaces. 

During the selection of these materials, 

consideration must also be given to 

ensure that the flammability 

characteristics of the materials will not 

be adversely affected by the use of 

cleaning agents and utensils used to 

remove cooking stains. 

6. The cooktop ventilation system 

ducting must be protected by a flame 

arrestor. In addition, procedures and 

time intervals must be established and 

included in the instructions for 

continued airworthiness to inspect and 

clean or replace the ventilation system 

to prevent a fire hazard from the 

accumulation of flammable oils. [Note: 

The applicant may find additional 

useful information in the Society of 

Automotive Engineers, Aerospace 

Recommended Practice 85, Rev. E, 

entitled, ‘‘Air Conditioning Systems for 

Subsonic Airplanes,’’ dated August 1, 

1991.] 

7. Means must be provided to contain 

spilled foods or fluids in a manner that 

prevents the creation of a slipping 

hazard to occupants, and that will not 

lead to the loss of structural strength 

due to corrosion. 

8. Cooktop installations must provide 

adequate space for the user to 

immediately escape a hazardous 

cooktop condition. 

9. A means to shut off power to the 

cooktop must be provided at the galley 

containing the cooktop and in the 

cockpit. If additional switches are 

introduced in the cockpit, revisions to 

smoke or fire emergency procedures of 

the airplane flight manual (AFM) will be 

required. 

10. Cooktop installations must 

incorporate a timer that will switch the 

heating elements off after a maximum 

time of 20 minutes. 

11. Instructions for the cabin crew to 

ensure safe operation of the cooktop lid 

and timer must be provided. 

12. Evidence must be provided that 

with the cooktop lid closed, the 

temperature set on ‘‘high,’’ and the 

timer at maximum, the cooktop will 

maintain safe operation and will not 

create a hazardous condition even with 

cooking oil in the cooktop.
