Background
On October 5, 2005, Embraer S.A.
applied for a type certificate for their
new Model EMB–500. The Model EMB–
500 is a normal category, low-winged
monoplane with ‘‘T’’ tailed vertical and
horizontal stabilizers, retractable
tricycle type landing gear and twin
turbofan engines mounted on the
aircraft fuselage. Its design
characteristics include a predominance
of metallic construction. The maximum
takeoff weight is 9,700 pounds, the VMO/
MMO is 275 KIAS/M 0.70 and maximum
altitude is 41,000 feet.
14 CFR part 23 has historically
addressed fire protection through
prevention, identification, and
containment. Prevention has been
provided through minimizing the
potential for ignition of flammable
fluids and vapors. Identification has
been provided by locating engines
within the pilots’ primary field of view
and/or with the incorporation of fire
detection systems. This has provided
both rapid detection of a fire and
confirmation when it was extinguished.
Containment has been provided through
the isolation of designated fire zones,
through flammable fluid shutoff valves,
and firewalls.
This containment philosophy also
ensures that components of the engine
control system will function effectively
to permit a safe shutdown of an engine.
However, containment has only been
demonstrated for 15 minutes. If a fire
occurs in traditional part 23 airplanes,
the appropriate corrective action is to
land as soon as possible. For a small,
simple airplane originally envisioned by
part 23, it is possible to descend and
land within 15 minutes; thus, the
occupants can safely exit the airplane
before the firewall is breached. These
simple airplanes normally have the
engine located away from critical flight
control systems and primary structure.
This has ensured that, throughout a fire
event, a pilot can continue safe flight,
and it has made the prediction of fire

engine fire becomes extremely critical
with the Model EMB–500 engine
location.
1. SC 23.1195—Add the requirements
of § 23.1195 while deleting the phrase,
‘‘For commuter category airplanes.’’
Applicability
Type Certification Basis
Under the provisions of 14 CFR 21.17,
Embraer S.A. must show that the Model
EMB–500 meets the applicable
provisions of 14 CFR part 23, as
amended by Amendments 23–1 through
23–55, thereto.
If the Administrator finds that the
applicable airworthiness regulations
(i.e., 14 CFR part 23) do not contain
adequate or appropriate safety standards
for the Model EMB–500 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 Model EMB–500 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, and the
FAA must issue a finding of regulatory
adequacy pursuant to section 611 of
Public Law 92–574, the ‘‘Noise Control
Act of 1972.’’
Special conditions, as appropriate, as
defined in 11.19, are issued under
§ 11.38, and become part of the type
certification basis under § 21.17(a)(2).
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(a)(1).

effects relatively easy. Other design
features of these simple aircraft, such as
low stall speeds and short landing
distances, ensure that even if an off-field
landing occurs, the potential for the
outcome being catastrophic has been
minimized.
Title 14 CFR part 23 did not envision
the type of configuration of the Model
EMB–500 airplane. The Model EMB–
500 incorporates two turbofan engines
located on pylons on either side of the
aft fuselage. These engines are not in the
pilots’ field of view. With the location
on the aft fuselage, the ability to visually
detect a fire is minimal.
The FAA has determined that notice
and opportunity for prior public
comment hereon are impracticable
because these procedures would
significantly delay issuance of the
design approval and thus delivery of the
affected aircraft. In addition, the
substance of these special conditions
has been subject to the public comment
process in several prior instances with
no substantive comments received. The
FAA therefore finds that good cause
exists for making these special
conditions effective upon issuance.
23.1195, Fire Extinguishing Systems
(a) Fire extinguishing systems must be
installed and compliance 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 extinguishing agent, the rate
of discharge, and the discharge
distribution must be adequate to
extinguish fires. An individual ‘‘oneshot’’ system may be used; and
(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) If an auxiliary power unit is
installed in any airplane certificated to
this part, that auxiliary power unit
compartment must be served by a fire
extinguishing system meeting the
requirements of paragraph (a)(2) of this
section.
2. SC 23.1197—Add the requirements
of § 23.1197 while deleting the phrase,
‘‘For commuter category airplanes.’’
Novel or Unusual Design Features
The Model EMB–500 incorporates
two turbofan engines located on pylons
on either side of the aft fuselage. These
engines are not in the pilots’ field of
view. The effects of a fire in such a
compartment are more varied and
adverse than the typical engine fire in
a simple part 23 airplane. With the
location on the aft fuselage, the ability
to visually detect a fire is minimal.
However, the ability to extinguish an
VerDate Aug<31>2005
14:58 Jan 17, 2008
Jkt 214001
As discussed above, these special
conditions are applicable to the Model
EMB–500. Should Embraer S. A. apply
later 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
§ 21.101(a)(1).
Good Cause
Conclusion
Under standard practice, the effective
date of final special conditions would
be 30 days after the date of publication
in the Federal Register; however, as the
certification date for the Embraer S. A.
Model EMB–500 is imminent, the FAA
finds that good cause exists to make
these special conditions effective upon
issuance.
This action affects only certain novel
or unusual design features on one
model, Model EMB–500, 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.

23.1197, Fire Extinguishing Agents
The following applies:
(a) Fire extinguishing agents must—
(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.
(b) 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—
(1) Five pounds or less of carbon
dioxide will be discharged under
established fire control procedures into
any fuselage compartment; or
(2) Protective breathing equipment is
available for each flight crewmember on
flight deck duty.

SUMMARY: The Equal Employment
Opportunity Commission is eliminating
three bases for dismissal of charges in
its procedural regulations because they
are no longer needed to accomplish the
Commission’s case management goals.

Thomas J. Schlageter, Assistant Legal
Counsel, or Mona Papillon, Senior
General Attorney, at (202) 663–4640

of this final rule are also available in the
following alternate formats: Large print,
braille, audiotape and electronic file on
computer disk. Requests for this notice
in an alternative format should be made
to EEOC’s Publication Center at 1–800–
669–3362 (voice) or 1–800–800–3302
(TTY).
SUPPLEMENTARY INFORMATION: Prior to
1977, the Commission’s procedural
regulations only authorized dismissal
when the Commission issued a no cause
determination, a charge was untimely,
or a charge failed to state a claim. In
1977, the Commission adopted three
additional bases for dismissal in order
to resolve charges that were timely and
stated a claim, but where the
Commission was unable to issue a
determination on the merits for various
reasons. These three bases are currently
set out in § 1601.18(b) through (d).
Paragraph (b) permits dismissal when
the charging party fails to cooperate.
Paragraph (c) permits dismissal when
the charging party cannot be located.
Paragraph (d) permits dismissal when
the charging party refuses to accept an
offer of full relief for the harm alleged
in the charge.
In 1995, the Commission adopted
Priority Charge Handling Procedures
(PCHP) to facilitate flexibility and
permit more strategic use of resources.
Among other things, PCHP authorized
field offices to issue final
determinations when further
investigation was not likely to lead to
evidence establishing a violation of the
employment discrimination statutes.
Thus, § 1601.18(b) through (d) are no
longer needed to accomplish the
Commission’s case management goals.
Their elimination is also consistent with
EEOC’s procedural regulations
governing the Age Discrimination in
Employment Act and the Equal Pay Act
which do not contain the dismissal
bases of failure to cooperate, to locate,
and to accept full relief.
In addition, the continued inclusion
of these dismissal bases in the
regulations is causing unnecessary
confusion. There is a split in the courts
regarding the proper interpretation of
paragraphs (b) through (d). Compare

Background
On October 5, 2005, Embraer S.A. applied for a type certificate for
their new Model EMB-500. The Model EMB-500 is a normal category, low-
winged monoplane with ``T'' tailed vertical and horizontal stabilizers,
retractable tricycle type landing gear and twin turbofan engines
mounted on the aircraft fuselage. Its design characteristics include a
predominance of metallic construction. The maximum takeoff weight is
9,700 pounds, the VMO/MMO is 275 KIAS/M 0.70 and
maximum altitude is 41,000 feet.
14 CFR part 23 has historically addressed fire protection through

[[Page 3386]]
effects relatively easy. Other design features of these simple
aircraft, such as low stall speeds and short landing distances, ensure
that even if an off-field landing occurs, the potential for the outcome
being catastrophic has been minimized.
Title 14 CFR part 23 did not envision the type of configuration of
the Model EMB-500 airplane. The Model EMB-500 incorporates two turbofan
engines located on pylons on either side of the aft fuselage. These
engines are not in the pilots' field of view. With the location on the
aft fuselage, the ability to visually detect a fire is minimal.
Type Certification Basis
Under the provisions of 14 CFR 21.17, Embraer S.A. must show that
the Model EMB-500 meets the applicable provisions of 14 CFR part 23, as
amended by Amendments 23-1 through 23-55, thereto.
If the Administrator finds that the applicable airworthiness
regulations (i.e., 14 CFR part 23) do not contain adequate or
appropriate safety standards for the Model EMB-500 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 Model EMB-500 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, and the FAA must issue a
finding of regulatory adequacy pursuant to section 611 of Public Law
92-574, the ``Noise Control Act of 1972.''
Special conditions, as appropriate, as defined in 11.19, are issued
under Sec. 11.38, and become part of the type certification basis
under Sec. 21.17(a)(2).
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 Sec. 21.101(a)(1).
Novel or Unusual Design Features
The Model EMB-500 incorporates two turbofan engines located on
pylons on either side of the aft fuselage. These engines are not in the
pilots' field of view. The effects of a fire in such a compartment are
more varied and adverse than the typical engine fire in a simple part
23 airplane. With the location on the aft fuselage, the ability to
visually detect a fire is minimal. However, the ability to extinguish
an engine fire becomes extremely critical with the Model EMB-500 engine
location.
Applicability
As discussed above, these special conditions are applicable to the
Model EMB-500. Should Embraer S. A. apply later 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 Sec. 21.101(a)(1).
Good Cause
The FAA has determined that notice and opportunity for prior public
comment hereon are impracticable because these procedures would
significantly delay issuance of the design approval and thus delivery
of the affected aircraft. In addition, the substance of these special
conditions has been subject to the public comment process in several
prior instances with no substantive comments received. The FAA
therefore finds that good cause exists for making these special
conditions effective upon issuance.
Conclusion
Under standard practice, the effective date of final special
conditions would be 30 days after the date of publication in the
Federal Register; however, as the certification date for the Embraer S.
A. Model EMB-500 is imminent, the FAA finds that good cause exists to
make these special conditions effective upon issuance.
This action affects only certain novel or unusual design features
on one model, Model EMB-500, 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.

Citation
The authority citation for these special conditions is as follows:
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.
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 Embraer S. A. Model EMB-500 airplanes.
1. SC 23.1195--Add the requirements of Sec. 23.1195 while deleting
the phrase, ``For commuter category airplanes.''
23.1195, Fire Extinguishing Systems
(a) Fire extinguishing systems must be installed and compliance
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 extinguishing
agent, the rate of discharge, and the discharge distribution must be
adequate to extinguish fires. An individual ``one-shot'' system may be
used; and
(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) If an auxiliary power unit is installed in any airplane
certificated to this part, that auxiliary power unit compartment must
be served by a fire extinguishing system meeting the requirements of
paragraph (a)(2) of this section.
2. SC 23.1197--Add the requirements of Sec. 23.1197 while deleting
the phrase, ``For commuter category airplanes.''
23.1197, Fire Extinguishing Agents
The following applies:
(a) Fire extinguishing agents must--
(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.
(b) 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 built-
in carbon dioxide fuselage compartment fire extinguishing systems for
which--
(1) Five pounds or less of carbon dioxide will be discharged under
established fire control procedures into any fuselage compartment; or
(2) Protective breathing equipment is available for each flight
crewmember on flight deck duty.

3. SC 23.1199--Add the requirements of Sec. 23.1199 while deleting
the phrase, ``For commuter category airplanes.''
23.1199, Extinguishing Agent Containers
The following applies:
(a) Each extinguishing agent container must have a pressure relief
to prevent bursting of the container by excessive internal pressures.
(b) 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.
(c) 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.
(d) The temperature of each container must be maintained, under
intended operating conditions, to prevent the pressure in the container
from--
(1) Falling below that necessary to provide an adequate rate of
discharge; or
(2) Rising high enough to cause premature discharge.
(e) If a pyrotechnic capsule is used to discharge the fire
extinguishing agent, each container must be installed so that
temperature conditions will not cause hazardous deterioration of the
pyrotechnic capsule.
4. SC 23.1201--Add the requirements of Sec. 23.1201 while deleting
the phrase, ``For commuter category airplanes.''
23.1201, Fire Extinguishing System Materials
The following apply:
(a) No material in any fire extinguishing system may react
chemically with any extinguishing agent so as to create a hazard.
(b) Each system component in an engine compartment must be
fireproof.
Issued in Kansas City, Missouri on January 7, 2008.
