This action proposes special conditions for the Airbus Model A318-112 airplane. This airplane as modified by Fokker Services B.V. will have a novel or unusual design feature associated with a cooktop installation. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

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, transport-category 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.
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.
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 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.
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.
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.
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.
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.
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,
