Special Conditions: Boeing Model 737-700 IGW Airplane (BBJ, S/N 34683); Certification of Cooktops, 63676-63678 [E6-18281]

Download as PDF 63676 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations SBA has determined that this direct final rule does not impose additional reporting or recordkeeping requirements under the Paperwork Reduction Act, 44 U.S.C., Chapter 35. The Regulatory Flexibility Act (RFA), 5 U.S.C. 601, requires administrative agencies to consider the effect of their actions on small entities, small nonprofit enterprises, and small local governments. Pursuant to the RFA, when an agency issues a rulemaking, the agency must prepare a regulatory flexibility analysis which describes the impact of the rule on small entities. However, section 605 of the RFA allows an agency to certify a rule, in lieu of preparing an analysis, if the rulemaking is not expected to have a significant economic impact on a substantial number of small entities. Within the meaning of RFA, SBA certifies that this rule will not have a significant economic impact on a substantial number of small entities. This rule is only changing the designations of the agency’s disaster offices and making conforming amendments to existing regulations on SBA’s Disaster Loan Program.

Background On August 31, 2005, PATS Aircraft LLC applied for a supplemental type certificate for the Boeing Model 737–700 IGW airplane (BBJ serial number 34683). The Boeing Model 737–700 IGW airplane is one of the Boeing Business Jet (BBJ) variants of Model 737 airplanes. It is a large transport category airplane powered by two CFM 56 engines, with a maximum takeoff weight of 171,000 pounds. The modified Boeing Model 737–700 IGW airplane, BBJ serial number 34683, operates with a 2-pilot crew, up to 4 flight attendants, and can hold up to 18 passengers. The modification consists of installing an electrically heated surface, called a cooktop. Cooktops introduce high heat, smoke, and the possibility of fire into the passenger cabin environment. These potential hazards to the airplane and its occupants must be satisfactorily addressed. Since existing airworthiness regulations do not contain safety standards addressing cooktops, we issue these special conditions. Type Certification Basis Under the provisions of § 21.101, PATS Aircraft LLC must show that the 737–700 IGW, as changed, continues to meet the applicable provisions of the regulations incorporated by reference in Type Certificate No. A16WE 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 A16WE are part 25, as amended by Amendments 25–1 through 25–77, with reversions to earlier amendments, voluntary compliance to later amendments, PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 63677 special conditions, equivalent safety findings, and exemptions listed in the type certificate data sheet. If the Administrator finds that the applicable airworthiness regulations (14 Code of Federal Regulations (CFR) part 25, as amended) do not contain adequate or appropriate safety standards for the 737–700 IGW 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 737–700 IGW 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 § 11.19, under § 11.38, and they become part of the type certification basis under § 21.101. Novel or Unusual Design Features As noted earlier, the modification of the Boeing Model 737–700 IGW airplane, BBJ serial number 34683, will incorporate a cooktop 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. So this 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 implications for passenger and airplane safety if appropriate requirements are not established for their installation and use. These special conditions apply to cooktops with electrically powered burners. Use of an open flame cooktop (employing natural gas, for example) is beyond the scope of these special conditions and would require separate rulemaking action. The requirements identified in these special conditions are in addition to those considerations E:\FR\FM\31OCR1.SGM 31OCR1 63678 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations identified in Advisory Circular (AC) 25– 10, ‘‘Guidance for Installation of Miscellaneous Non-required Electrical Equipment,’’ and those in AC 25–17, ‘‘Transport Airplane Cabin Interiors Crashworthiness Handbook.’’ The intent of these special conditions is to provide a level of safety consistent with that on similar airplanes without cooktops. Applicability As discussed above, these special conditions are applicable to the 737–700 IGW airplane, BBJ serial number 34683, modified by PATS Aircraft LLC. Should PATS Aircraft LLC apply at a later date for a supplemental type certificate to modify any other model included on Type Certificate No. A16WE to incorporate the same novel or unusual design feature, these 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. Under standard practice, the effective date of final special conditions would be 30 days after the date of publication in the Federal Register. However, because the certification date for the subject modification to the Boeing Model 737–700 IGW is imminent, the FAA finds that good cause exists to make these special conditions effective upon issuance.

The Special Conditions Accordingly, pursuant to the authority delegated to me by the Administrator, the following special conditions are issued as part of the type certification basis for the Boeing Model 737–700 IGW BBJ airplane, BBJ serial number 34683, modified by PATS Aircraft LLC: I cprice-sewell on PROD1PC66 with RULES Cooktop Installations With ElectricallyPowered Burners 1. A design feature must be installed to minimize potential for inadvertent personnel contact with hot surfaces of both the cooktop and cookware. Examples of such safety features are conspicuous burner-on indicators, physical barriers, or handholds. VerDate Aug<31>2005 15:23 Oct 30, 2006 Jkt 211001 Conditions of turbulence must be considered. 2. The design must include sufficient means to restrain cookware and representative contents, such as soups or sauces, while in place on the cooktop, from effects of flight loads and turbulence. (a) Restraints must be provided to preclude hazardous movement of cookware and contents. These restraints must accommodate any cookware identified for use with the cooktop. (b) Restraints must be designed to be easily used and effective in service. The cookware restraint system should also be designed so it cannot be easily disabled, thus rendering it unusable. (c) Placarding must be installed that prohibits use of cookware that cannot be accommodated by the restraint system. 3. Placarding must be installed that prohibits use of cooktops (power on any burner) during taxi, takeoff, and landing (TTL). 4. Means must be provided to address the possibility of a fire occurring on or in the immediate vicinity of the cooktop caused by materials or grease inadvertently coming in contact with the burners. 5. Galley surfaces 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 complying with flammability requirements of 14 CFR part 25, Appendix F part III. This requirement is in addition to the flammability standards typically required of these galley surface materials. During selection of these materials, consideration must also be given to ensuring that the flammability characteristics of the materials will not be adversely affected by cleaning agents and utensils used to remove cooking stains. 6. 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 accumulation of flammable oils. These procedures and time intervals must be included in the Instructions for Continued Airworthiness (ICA). The ventilation system ducting must be protected by a flame arrestor.

E, dated August 1, 1991. • Placarding must be installed that prohibits power on any burner when the cooktop is unattended. This would prohibit a single person from cooking on the cooktop and intermittently serving food to passengers while any burner is powered. A fire detector which provides an audible warning in the passenger cabin must be installed in the vicinity of the cooktop. In addition, a fire extinguisher of appropriate size and extinguishing agent must be installed in the immediate vicinity of the cooktop. A fire on or around the cooktop must not block access to the extinguisher. One of the fire extinguishers required by § 25.851 may be used to satisfy this requirement if the total complement of extinguishers can be evenly distributed throughout the cabin. If this is not possible, then the extinguisher in the galley area would be additional. or • An automatic, thermally-activated fire suppression system must be installed to extinguish a fire on the cooktop and immediately adjacent surfaces. The agent used in the system must be an approved total flooding agent suitable for use in occupied areas. The fire suppression system must have a manual override. Automatic activation of the fire suppression system must also automatically shut off power to the cooktop. PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 7. Means must be provided to contain spilled foods or fluids in a manner that will prevent creation of a slipping hazard to occupants and will not lead to loss of structural strength due to airplane 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 both in 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 AFM will be required. 10. A readily deployable cover must be provided to cover the cooktop during taxi, takeoff, and landing (TT&L) operation. Deployment of the cover must automatically shut off power to the cooktop.

Background

    On August 31, 2005, PATS Aircraft LLC applied for a supplemental 
type certificate for the Boeing Model 737-700 IGW airplane (BBJ serial 
number 34683). The Boeing Model 737-700 IGW airplane is one of the 
Boeing Business Jet (BBJ) variants of Model 737 airplanes. It is a 
large transport category airplane powered by two CFM 56 engines, with a 
maximum takeoff weight of 171,000 pounds. The modified Boeing Model 
737-700 IGW airplane, BBJ serial number 34683, operates with a 2-pilot 
crew, up to 4 flight attendants, and can hold up to 18 passengers.
    The modification consists of installing an electrically heated 
surface, called a cooktop. Cooktops introduce high heat, smoke, and the 
possibility of fire into the passenger cabin environment. These 
potential hazards to the airplane and its occupants must be 
satisfactorily addressed. Since existing airworthiness regulations do 
not contain safety standards addressing cooktops, we issue these 
special conditions.

Type Certification Basis

    Under the provisions of Sec.  21.101, PATS Aircraft LLC must show 
that the 737-700 IGW, as changed, continues to meet the applicable 
provisions of the regulations incorporated by reference in Type 
Certificate No. A16WE 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 A16WE are part 25, as amended by Amendments 25-1 through 
25-77, 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 (14 Code of Federal Regulations (CFR) part 25, as amended) 
do not contain adequate or appropriate safety standards for the 737-700 
IGW because of a novel or unusual design feature, special conditions 
are prescribed under the provisions of Sec.  21.16.
    In addition to the applicable airworthiness regulations and special 
conditions, the 737-700 IGW 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 Sec.  11.19, under 
Sec.  11.38, and they become part of the type certification basis under 
Sec.  21.101.

Novel or Unusual Design Features

    As noted earlier, the modification of the Boeing Model 737-700 IGW 
airplane, BBJ serial number 34683, will incorporate a cooktop 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. So this 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 implications for passenger and airplane 
safety if appropriate requirements are not established for their 
installation and use. These special conditions apply to cooktops with 
electrically powered burners. Use of an open flame cooktop (employing 
natural gas, for example) is beyond the scope of these special 
conditions and would require separate rulemaking action. The 
requirements identified in these special conditions are in addition to 
those considerations

[[Page 63678]]

identified in Advisory Circular (AC) 25-10, ``Guidance for Installation 
of Miscellaneous Non-required Electrical Equipment,'' and those in AC 
25-17, ``Transport Airplane Cabin Interiors Crashworthiness Handbook.'' 
The intent of these special conditions is to provide a level of safety 
consistent with that on similar airplanes without cooktops.

Applicability

    As discussed above, these special conditions are applicable to the 
737-700 IGW airplane, BBJ serial number 34683, modified by PATS 
Aircraft LLC. Should PATS Aircraft LLC apply at a later date for a 
supplemental type certificate to modify any other model included on 
Type Certificate No. A16WE to incorporate the same novel or unusual 
design feature, these 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.
    Under standard practice, the effective date of final special 
conditions would be 30 days after the date of publication in the 
Federal Register. However, because the certification date for the 
subject modification to the Boeing Model 737-700 IGW is imminent, the 
FAA finds that good cause exists to make these special conditions 
effective upon issuance.

Accordingly, pursuant to the authority delegated to me by the 
Administrator, the following special conditions are issued as part of 
the type certification basis for the Boeing Model 737-700 IGW BBJ 
airplane, BBJ serial number 34683, modified by PATS Aircraft LLC:

Cooktop Installations With Electrically-Powered Burners

    1. A design feature must be installed to minimize potential for 
inadvertent personnel contact with hot surfaces of both the cooktop and 
cookware. Examples of such safety features are conspicuous burner-on 
indicators, physical barriers, or handholds. Conditions of turbulence 
must be considered.
    2. The design must include sufficient means to restrain cookware 
and representative contents, such as soups or sauces, while in place on 
the cooktop, from effects of flight loads and turbulence.
    (a) Restraints must be provided to preclude hazardous movement of 
cookware and contents. These restraints must accommodate any cookware 
identified for use with the cooktop.
    (b) Restraints must be designed to be easily used and effective in 
service. The cookware restraint system should also be designed so it 
cannot be easily disabled, thus rendering it unusable.
    (c) Placarding must be installed that prohibits use of cookware 
that cannot be accommodated by the restraint system.
    3. Placarding must be installed that prohibits use of cooktops 
(power on any burner) during taxi, takeoff, and landing (TTL).
    4. Means must be provided to address the possibility of a fire 
occurring on or in the immediate vicinity of the cooktop caused by 
materials or grease inadvertently coming in contact with the burners.

    Note: Two acceptable means of complying with this requirement 
are as follows:

     Placarding must be installed that prohibits power on any 
burner when the cooktop is unattended. This would prohibit a single 
person from cooking on the cooktop and intermittently serving food to 
passengers while any burner is powered. A fire detector which provides 
an audible warning in the passenger cabin must be installed in the 
vicinity of the cooktop. In addition, a fire extinguisher of 
appropriate size and extinguishing agent must be installed in the 
immediate vicinity of the cooktop. A fire on or around the cooktop must 
not block access to the extinguisher. One of the fire extinguishers 
required by Sec.  25.851 may be used to satisfy this requirement if the 
total complement of extinguishers can be evenly distributed throughout 
the cabin. If this is not possible, then the extinguisher in the galley 
area would be additional.

 or
     An automatic, thermally-activated fire suppression system 
must be installed to extinguish a fire on the cooktop and immediately 
adjacent surfaces. The agent used in the system must be an approved 
total flooding agent suitable for use in occupied areas. The fire 
suppression system must have a manual override. Automatic activation of 
the fire suppression system must also automatically shut off power to 
the cooktop.
    5. Galley surfaces 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 complying with flammability requirements of 14 
CFR part 25, Appendix F part III. This requirement is in addition to 
the flammability standards typically required of these galley surface 
materials. During selection of these materials, consideration must also 
be given to ensuring that the flammability characteristics of the 
materials will not be adversely affected by cleaning agents and 
utensils used to remove cooking stains.
    6. 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 accumulation of 
flammable oils. These procedures and time intervals must be included in 
the Instructions for Continued Airworthiness (ICA). The ventilation 
system ducting must be protected by a flame arrestor.

Automotive Engineers, Aerospace Recommended Practice 85, Rev. E, 
dated August 1, 1991.


    7. Means must be provided to contain spilled foods or fluids in a 
manner that will prevent creation of a slipping hazard to occupants and 
will not lead to loss of structural strength due to airplane 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 both 
in 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 AFM will be required.
    10. A readily deployable cover must be provided to cover the 
cooktop during taxi, takeoff, and landing (TT&L) operation. Deployment 
of the cover must automatically shut off power to the cooktop.
