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.

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.
Note: Two acceptable means of complying
with this requirement are as follows:
Note: The applicant may find additional
useful information in ‘‘Air Conditioning
Systems for Subsonic Airplanes,’’ Society of
Automotive Engineers, Aerospace
Recommended Practice 85, Rev. 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.

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

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.

The Special Conditions
0
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.
Note: The applicant may find additional useful information in
``Air Conditioning Systems for Subsonic Airplanes,'' Society of
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.
