Background
On January 28, 2004, Cessna Aircraft
Company; One Cessna Boulevard; Post
Office Box 7704; Wichita, KS 67277,
made an application to the FAA for a
new Type Certificate for the Cessna
Model 510 Mustang. If approved, the
Cessna 510 would be approved under
TC No. A24CE. The Cessna Model 510
Mustang is an all new, high
performance, low wing, aft fuselage
mounted twin turbofan engine powered
aircraft in the Normal Category
including flight into known icing
conditions and single pilot operations.
The Model 510 is to use existing Cessna
Citation construction materials and
methods. The design criteria includes:
8,480 pounds maximum ramp weight,
8,395 pounds maximum takeoff weight,
250 KCAS/0.63 Mach VMO/MMO, and
a 41,000 foot maximum altitude.
Type Certification Basis
Under the provisions of 14 CFR, part
21, § 21.17, Cessna Aircraft Company
must show that the Cessna Model 510
Mustang meets the applicable
provisions of 14 CFR, part 23, effective
February 1, 1965, as amended by
Amendments 23–1 through Amendment
23–54, effective September 14, 2000; 14

on the date of type certification; 14 CFR,
part 34; exemptions, if any; and the
special conditions adopted by this
rulemaking action.
Authority: 49 U.S.C. 106(g); 40113 and
44701; 14 CFR 21.16 and 21.17; and 14 CFR
11.38 and 11.19.
Discussion
The Proposed Special Conditions
Special conditions, as appropriate, as
defined in § 11.19, are issued in
accordance with § 11.38, and become
part of the type certification basis in
accordance with § 21.17.
Special conditions are initially
applicable to the model for which they
are issued. Should the type certificate
for that model be amended later to
include any other model that
incorporates the same novel or unusual
design feature, the special conditions
would also apply to the other model
under the provisions of § 21.101.
Accordingly, the Federal Aviation
Administration (FAA) proposes the
following special conditions as part of
the type certification basis for the
Cessna Model 510 airplane:
Novel or Unusual Design Features
The Cessna Model 510 Mustang will
incorporate the following novel or
unusual design features:
Engine Fire Extinguishing System
The Model 510 design includes
engines mounted aft on the fuselage;
therefore, early visual detection of
engine fires is precluded. The
applicable existing regulations do not
require fire extinguishing systems for
engines. Aft mounted engine
installations were not envisaged in the
development of part 23; therefore,
special conditions for a fire
extinguishing system with the
applicable agents, containers, and
materials for the engines of the Model
510 are appropriate.
Applicability
As discussed above, these special
conditions are applicable to the Cessna
Model 510. Should Cessna Aircraft
Company apply at a later date for a
change to the type certificate to include
another model incorporating the same
novel or unusual design feature, the
special conditions would apply to that
model as well under the provisions of
§ 21.101.
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 it affects only the
applicant who applied to the FAA for
approval of these features on the
airplane identified.

The authority citation for these
Special Conditions is as follows:
SC23.1195 Engine Fire Extinguishing
System
(a) Fire extinguishing systems must be
installed and compliance must be
shown with the following:
(1) Except for combustor, turbine, and
tailpipe sections of turbine-engine
installations that contain lines or
components carrying flammable fluids
or gases for which a fire originating in
these sections is shown to be
controllable, a fire extinguisher system
must serve each engine compartment.
(2) The fire extinguishing system, the
quantity of the extinguishing agent, the
rate of discharge, and the discharge
distribution must be adequate to
extinguish fires. An individual ‘‘one
shot’’ system may be used.
(3) The fire extinguishing system for
a nacelle must be able to simultaneously
protect each compartment of the nacelle
for which protection is provided.
(b) Fire extinguishing agents must
meet the following requirements:
(1) Be capable of extinguishing flames
emanating from any burning fluids or
other combustible materials in the area
protected by the fire extinguishing
system; and
(2) Have thermal stability over the
temperature range likely to be
experienced in the compartment in
which they are stored.
(3) If any toxic extinguishing agent is
used, provisions must be made to
prevent harmful concentrations of fluid
or fluid vapors (from leakage during
normal operation of the airplane or as a
result of discharging the fire
extinguisher on the ground or in flight)
from entering any personnel
compartment, even though a defect may
exist in the extinguishing system. This
must be shown by test except for builtin carbon dioxide fuselage compartment
fire extinguishing systems for which:
(i) Five pounds or less of carbon
dioxide will be discharged, under
established fire control procedures, into
any fuselage compartment; or
(ii) Protective breathing equipment is
available for each flight crewmember on
flight deck duty.

(c) Fire extinguishing agent containers
must meet the following requirements:
(1) Each extinguishing agent container
must have a pressure relief to prevent
bursting of the container by excessive
internal pressures.
(2) The discharge end of each
discharge line from a pressure relief
connection must be located so that
discharge of the fire extinguishing agent
would not damage the airplane. The line
must also be located or protected to
prevent clogging caused by ice or other
foreign matter.
(3) A means must be provided for
each fire extinguishing agent container
to indicate that the container has
discharged or that the charging pressure
is below the established minimum
necessary for proper functioning.
(4) The temperature of each container
must be maintained, under intended
operating conditions, to prevent the
pressure in the container from falling
below that necessary to provide an
adequate rate of discharge, or rising high
enough to cause premature discharge.
(5) If a pyrotechnic capsule is used to
discharge the extinguishing agent, each
container must be installed so that
temperature conditions will not cause
hazardous deterioration of the
pyrotechnic capsule.
(d) Fire extinguisher system materials
must meet the following requirements:
(1) No material in any fire
extinguishing system may react
chemically with any extinguishing agent
so as to create a hazard.
(2) Each system component in an
engine compartment must be fireproof.

ACTION: Notice of proposed rulemaking.
AGENCY:
SUMMARY: EPA is seeking comment on
two alternative proposals regarding
reformulated gasoline requirements for
an area formerly classified as a severe
ozone nonattainment area under the 1hour ozone national ambient air quality
standard (‘‘NAAQS’’ or ‘‘standard’’) that
was redesignated to attainment for that
standard before its revocation, and
which is currently designated as
nonattaiment for the 8-hour ozone
standard. Under the first option, this
area would be required to use federal
reformulated gasoline (RFG) at least
until it is redesignated to attainment for
the 8-hr NAAQS. Under the second
option, the State could request the
removal of RFG, and EPA would grant
such a request upon a demonstration
that removal would not result in loss of
any RFG-related emission reductions
relied upon in the State’s
Implementation Plan (SIP) for ozone.
Atlanta is the only area that falls within
the scope of this proposal.

protected to prevent clogging caused by ice or other foreign matter.
(3) A means must be provided for each fire extinguishing agent
container to indicate that the container has discharged or that the
charging pressure is below the established minimum necessary for proper
functioning.
(4) The temperature of each container must be maintained, under
intended operating conditions, to prevent the pressure in the container
from falling below that necessary to provide an adequate rate of
discharge, or rising high enough to cause premature discharge.
(5) If a pyrotechnic capsule is used to discharge the extinguishing
agent, each container must be installed so that temperature conditions
will not cause hazardous deterioration of the pyrotechnic capsule.
(d) Fire extinguisher system materials must meet the following
requirements:
(1) No material in any fire extinguishing system may react
chemically with any extinguishing agent so as to create a hazard.
(2) Each system component in an engine compartment must be
fireproof.
