process. While we received comments
on the previously-proposed special
conditions and carefully reviewed them,
we determined that no changes were
needed to the special conditions, as
proposed. In addition, notice and
opportunity for prior public comment
are impracticable because these

Background
On July 5, 2007, ABX Air, Inc. of
Wilmington, Ohio applied for a
supplemental type certificate to install a
satellite communication system on
Boeing Model 767–200, –300, and
–300F series airplanes. The satellite
communication system contains the
following equipment:
• Wingspeed Corporation Aircraft
Communication Unit,
• Sensor Systems GPS/Iridium
Antennae,
• Satellite Phone Handset,
• DAC International Class II GEN–X
Electronic Flight Bag System, and

At present, there is limited experience
with use of rechargeable lithium ion
batteries in applications involving
commercial aviation. However, other
users of this technology, ranging from
wireless telephone manufacturers to the
electric vehicle industry, have noted
safety problems with lithium ion
batteries. These problems include
overcharging, over-discharging, and
flammability of cell components.
1. Overcharging
In general, lithium ion batteries are
significantly more susceptible to
internal failures that can result in selfsustaining increases in temperature and
pressure (i.e., thermal runaway) than
their nickel-cadmium or lead-acid
counterparts. This is especially true for
overcharging that causes heating and
destabilization of the components of the
cell, leading to the formation (by
plating) of highly unstable metallic
lithium. The metallic lithium can ignite,
resulting in a self-sustaining fire or
explosion. Finally, the severity of
thermal runaway due to overcharging
increases with increasing battery
capacity due to the higher amount of
electrolyte in large batteries.
2. Over-Discharging
Discharge of some types of lithium
ion batteries beyond a certain voltage
(typically 2.4 volts) can cause corrosion
of the electrodes of the cell, resulting in
loss of battery capacity that cannot be
reversed by recharging. This loss of
capacity may not be detected by the
simple voltage measurements
commonly available to flight crews as a
means of checking battery status—a
problem shared with nickel-cadmium
batteries.
3. Flammability of Cell Components
Unlike nickel-cadmium and lead-acid
batteries, some types of lithium ion
batteries use liquid electrolytes that are
flammable. The electrolyte can serve as
a source of fuel for an external fire, if
there is a breach of the battery
container.
These problems experienced by users
of lithium ion batteries raise concern
about the use of these batteries in
commercial aviation. Accordingly, the
proposed use of lithium ion batteries in
a satellite communication system on
Boeing Model 767–200, –300, and
–300F series airplanes has prompted the
FAA to review the adequacy of existing
regulations in 14 CFR 25. Our review
indicates that the existing regulations do
not adequately address several failure,
operational, and maintenance
characteristics of lithium ion batteries

Federal Register / Vol. 73, No. 26 / Thursday, February 7, 2008 / Rules and Regulations
rfrederick on PROD1PC67 with RULES
that could affect the safety and
reliability of lithium ion battery
installations.
The intent of these special conditions
is to establish appropriate airworthiness
standards for lithium ion batteries in
Boeing Model 767–200, –300, and
–300F series airplanes modified by ABX
Air Inc. and to ensure, as required by 14
CFR 25.601, that these battery
installations are not hazardous or
unreliable. Accordingly, these special
conditions include the following
requirements:
• Those provisions of 14 CFR 25.1353
which are applicable to lithium ion
batteries.
• The flammable fluid fire protection
provisions of 14 CFR 25.863.
In the past, this regulation was not
applied to batteries of transport category
airplanes, since the electrolytes used in
lead-acid and nickel-cadmium batteries
are not flammable.
• New requirements to address the
hazards of overcharging and overdischarging that are unique to lithium
batteries.
• New Instructions for Continuous
Airworthiness that include maintenance
requirements to ensure that batteries
used as spares are maintained in an
appropriate state of charge.
Type Certification Basis
Under the provisions of 14 CFR
21.101, ABX Air, Inc. must show that
the Boeing Model 767–200, –300 and
–300F series airplanes, as changed,
continue to meet the applicable
provisions of the regulations
incorporated by reference in Type
Certificate No. A1NM 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 certification basis for Boeing
Model 767–200, –300, and –300F series
airplanes includes applicable sections of
14 CFR part 25, effective July 30, 1982,
as amended by Amendments 25–1
through 25–45, except for portions of
Amendment 25.38. In addition, the
certification basis includes certain
special conditions, exemptions,
equivalent levels of safety, or later
amended sections of the applicable part
25 that are not relevant to these special
conditions.
If the Administrator finds that the
applicable airworthiness regulations
(i.e., part 25, as amended) do not
contain adequate or appropriate safety
standards for Boeing Model 767–200,
–300, and –300F series airplanes
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 Boeing Model 767–200,
–300, and –300F series airplanes 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 14 CFR 11.19, under 14 CFR
11.38, and they become part of the type
certification basis in accordance with
§ 21.101.
Special conditions are initially
applicable to the models for which they
are issued. Should ABX Air, Inc. apply
for a supplemental type certificate to
modify any other model included on
Type Certificate No. A1NM to
incorporate the same or similar novel or
unusual design feature, these special
conditions would also apply to the other
model.
Novel or Unusual Design Features
The Boeing Model 767–200, –300, and
300F series airplanes—as modified by
ABX Air Inc. to include a satellite
communication system which uses
lithium ion battery technology—will
incorporate a novel or unusual design
feature. Because of rapid improvements
in airplane technology, the applicable
airworthiness regulations do not contain
adequate or appropriate safety standards
for this design feature. These 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.
The satellite communication system
will include a lithium ion battery
installation. Large, high capacity,
rechargeable lithium ion batteries are a
novel or unusual design feature in
transport category airplanes. This type
of battery has certain failure,
operational, and maintenance
characteristics that differ significantly
from those of the nickel-cadmium and
lead-acid rechargeable batteries
currently approved for installation on
large transport category airplanes. The
FAA issues these special conditions to
require that (1) all characteristics of the
lithium ion battery and its installation
that could affect safe operation of the
satellite communication system are
addressed, and (2) appropriate
maintenance requirements are
established to ensure that electrical
power is available from the batteries
when it is needed.

Applicability
As discussed above, these special
conditions are applicable to the Boeing
Model 767–200, –300, and –300F series
airplanes as modified by ABX Air Inc.
Should ABX Air, Inc. apply at a later
date for a supplemental type certificate
to modify any other model included on
Type Certificate No. A1NM 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 of the Boeing
Model 767–200, –300, and 300F series
airplanes as modified by ABX Air Inc.
It is not a rule of general applicability
and affects only the applicant which
applied to the FAA for approval of these
features on the airplane.
The substance of these special
conditions has been subjected to the
notice and comment period in several
prior instances and has been derived
without substantive change from those
previously issued. It is unlikely that
prior public comment would result in a
significant change from the substance
contained herein. For this reason and
because a delay would significantly
affect the certification of the airplane
which is imminent, the FAA has
determined that prior public notice and
comment are unnecessary and
impracticable and that good cause exists
for adopting these special conditions
upon issuance. The FAA is requesting
comments to allow interested persons to
submit views that may not have been
submitted in response to the prior
opportunities for comments described
above.

special conditions is as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701,
44702, 44704.
The Special Conditions
The FAA proposes the following
special conditions as part of the type
certification basis for Boeing Model
767–200, –300, and 300F series
airplanes modified by ABX Air Inc. in
lieu of the requirements of 14 CFR
25.1353(c)(1) through (c)(4),
Amendment 25–113.
Lithium ion batteries and battery
installations on Boeing 767–200, –300,
and –300F series airplanes must be
designed and installed as follows:
(1) Safe cell temperatures and
pressures must be maintained during

Federal Register / Vol. 73, No. 26 / Thursday, February 7, 2008 / Rules and Regulations
any foreseeable charging or discharging
condition and during any failure of the
charging or battery monitoring system
not shown to be extremely remote. The
lithium ion battery installation must
preclude explosion in the event of those
failures.
(2) Design of the lithium ion batteries
must preclude the occurrence of selfsustaining, uncontrolled increases in
temperature or pressure.
(3) No explosive or toxic gases
emitted by any lithium ion battery in
normal operation or as the result of any
failure of the battery charging system,
monitoring system, or battery
installation which is not shown to be
extremely remote may accumulate in
hazardous quantities within the
airplane.
(4) Installations of lithium ion
batteries must meet the requirements of
14 CFR 25.863(a) through (d).
(5) No corrosive fluids or gases that
may escape from any lithium ion battery
may damage surrounding structure or
any adjacent systems, equipment, or
electrical wiring of the airplane in such
a way as to cause a major or more severe
failure condition, in accordance with 14
CFR 25.1309 (b) and applicable
regulatory guidance.
(6) Each lithium ion battery
installation must have provisions to
prevent any hazardous effect on
structure or essential systems caused by
the maximum amount of heat the
battery can generate during a short
circuit of the battery or of its individual
cells.
(7) Lithium ion battery installations
must have a system to control the
charging rate of the battery
automatically, so as to prevent battery
overheating or overcharging, and,
(i) A battery temperature sensing and
over-temperature warning system with a
means for automatically disconnecting
the battery from its charging source in
the event of an over-temperature
condition, or
(ii) A battery failure sensing and
warning system with a means for
automatically disconnecting the battery
from its charging source in the event of
battery failure.
(8) Any lithium ion battery
installation whose function is required
for safe operation of the airplane must
incorporate a monitoring and warning
feature that will provide an indication
to the appropriate flight crewmembers
whenever the state-of-charge of the
batteries has fallen below levels
considered acceptable for dispatch of
the airplane.
(9) The Instructions for Continued
Airworthiness required by 14 CFR
25.1529 must contain maintenance
VerDate Aug<31>2005
15:02 Feb 06, 2008
Jkt 214001
requirements to assure that the lithium
ion battery is sufficiently charged at
appropriate intervals specified by the
battery manufacturer to ensure that
batteries whose function is required for
safe operation of the airplane will not
degrade below specified ampere-hour
levels sufficient to power the electronic
flight bag (EFB) applications that are
required for continued safe flight and
landing. The Instructions for Continued
Airworthiness must also contain
procedures for the maintenance of
lithium ion batteries in spares storage to
prevent the replacement of batteries
whose function is required for safe
operation of the airplane with batteries
that have experienced degraded charge
retention ability or other damage due to
prolonged storage at a low state of
charge. Precautions should be included
in the Instructions for Continued
Airworthiness maintenance instructions
to prevent mishandling of the lithium
ion battery which could result in shortcircuit or other unintentional damage
that could result in personal injury or
property damage.
Note 1: The term, ‘‘sufficiently charged’’
means the charge that is applied to
rechargeable lithium ion batteries, which
diminishes during the life of batteries with
respect to the retentive capacity of the
batteries to deliver available power—where
capacity is the total quantity of electricity of
a cell or battery, expressed in ampere-hours.
Battery life is influenced by its internal
chemical reaction and by other factors, such
as temperature, shock, the number of
recharges, etc.
Note 2: These special conditions are not
intended to replace 14 CFR 25.1353(c),
Amendment 25–113 in the certification basis
of the ABX, Air Inc supplemental type
certificate. These special conditions apply
only to lithium ion batteries and their
installations. The requirements of 14 CFR
25.1353(c), Amendment 25–113 remain in
effect for batteries and battery installations
on the ABX Air supplemental type certificate
that do not use lithium ion batteries.
Compliance with the requirements of
this Special Condition must be shown
by test or analysis, with the concurrence
of the Chicago Aircraft Certification
Office.

Background
On July 5, 2007, ABX Air, Inc. of Wilmington, Ohio applied for a
supplemental type certificate to install a satellite communication
system on Boeing Model 767-200, -300, and -300F series airplanes. The
satellite communication system contains the following equipment:
Wingspeed Corporation Aircraft Communication Unit,
Sensor Systems GPS/Iridium Antennae,

overcharging, over-discharging, and flammability of cell components.
1. Overcharging
In general, lithium ion batteries are significantly more
susceptible to internal failures that can result in self-sustaining
increases in temperature and pressure (i.e., thermal runaway) than
their nickel-cadmium or lead-acid counterparts. This is especially true
for overcharging that causes heating and destabilization of the

Accordingly, the proposed use of lithium ion batteries in a satellite
communication system on Boeing Model 767-200, -300, and -300F series
airplanes has prompted the FAA to review the adequacy of existing
regulations in 14 CFR 25. Our review indicates that the existing
regulations do not adequately address several failure, operational, and
maintenance characteristics of lithium ion batteries
[[Page 7204]]
that could affect the safety and reliability of lithium ion battery
installations.
The intent of these special conditions is to establish appropriate
airworthiness standards for lithium ion batteries in Boeing Model 767-
200, -300, and -300F series airplanes modified by ABX Air Inc. and to
ensure, as required by 14 CFR 25.601, that these battery installations
are not hazardous or unreliable. Accordingly, these special conditions
include the following requirements:
Those provisions of 14 CFR 25.1353 which are applicable to
lithium ion batteries.
The flammable fluid fire protection provisions of 14 CFR
25.863.
In the past, this regulation was not applied to batteries of
transport category airplanes, since the electrolytes used in lead-acid
and nickel-cadmium batteries are not flammable.
New requirements to address the hazards of overcharging
and over-discharging that are unique to lithium batteries.
New Instructions for Continuous Airworthiness that include
maintenance requirements to ensure that batteries used as spares are
maintained in an appropriate state of charge.
Type Certification Basis
Under the provisions of 14 CFR 21.101, ABX Air, Inc. must show that
the Boeing Model 767-200, -300 and -300F series airplanes, as changed,
continue to meet the applicable provisions of the regulations
incorporated by reference in Type Certificate No. A1NM 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 certification basis for Boeing Model 767-200, -300, and -300F
series airplanes includes applicable sections of 14 CFR part 25,
effective July 30, 1982, as amended by Amendments 25-1 through 25-45,
except for portions of Amendment 25.38. In addition, the certification
basis includes certain special conditions, exemptions, equivalent
levels of safety, or later amended sections of the applicable part 25
that are not relevant to these special conditions.
If the Administrator finds that the applicable airworthiness
regulations (i.e., part 25, as amended) do not contain adequate or
appropriate safety standards for Boeing Model 767-200, -300, and -300F
series airplanes 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 Boeing Model 767-200, -300, and -300F series airplanes
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 14 CFR 11.19,
under 14 CFR 11.38, and they become part of the type certification
basis in accordance with Sec. 21.101.
Special conditions are initially applicable to the models for which
they are issued. Should ABX Air, Inc. apply for a supplemental type
certificate to modify any other model included on Type Certificate No.
A1NM to incorporate the same or similar novel or unusual design
feature, these special conditions would also apply to the other model.
Novel or Unusual Design Features
The Boeing Model 767-200, -300, and 300F series airplanes--as
modified by ABX Air Inc. to include a satellite communication system
which uses lithium ion battery technology--will incorporate a novel or
unusual design feature. Because of rapid improvements in airplane
technology, the applicable airworthiness regulations do not contain
adequate or appropriate safety standards for this design feature. These
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.
The satellite communication system will include a lithium ion
battery installation. Large, high capacity, rechargeable lithium ion
batteries are a novel or unusual design feature in transport category
airplanes. This type of battery has certain failure, operational, and
maintenance characteristics that differ significantly from those of the
nickel-cadmium and lead-acid rechargeable batteries currently approved
for installation on large transport category airplanes. The FAA issues
these special conditions to require that (1) all characteristics of the
lithium ion battery and its installation that could affect safe
operation of the satellite communication system are addressed, and (2)
appropriate maintenance requirements are established to ensure that
electrical power is available from the batteries when it is needed.
Applicability
As discussed above, these special conditions are applicable to the
Boeing Model 767-200, -300, and -300F series airplanes as modified by
ABX Air Inc. Should ABX Air, Inc. apply at a later date for a
supplemental type certificate to modify any other model included on
Type Certificate No. A1NM 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
of the Boeing Model 767-200, -300, and 300F series airplanes as
modified by ABX Air Inc. It is not a rule of general applicability and
affects only the applicant which applied to the FAA for approval of
these features on the airplane.
The substance of these special conditions has been subjected to the
notice and comment period in several prior instances and has been
derived without substantive change from those previously issued. It is
unlikely that prior public comment would result in a significant change
from the substance contained herein. For this reason and because a
delay would significantly affect the certification of the airplane
which is imminent, the FAA has determined that prior public notice and
comment are unnecessary and impracticable and that good cause exists
for adopting these special conditions upon issuance. The FAA is
requesting comments to allow interested persons to submit views that
may not have been submitted in response to the prior opportunities for
comments described above.

The Special Conditions
The FAA proposes the following special conditions as part of the
type certification basis for Boeing Model 767-200, -300, and 300F
series airplanes modified by ABX Air Inc. in lieu of the requirements
of 14 CFR 25.1353(c)(1) through (c)(4), Amendment 25-113.
Lithium ion batteries and battery installations on Boeing 767-200,
-300, and -300F series airplanes must be designed and installed as
follows:
(1) Safe cell temperatures and pressures must be maintained during
[[Page 7205]]
any foreseeable charging or discharging condition and during any
failure of the charging or battery monitoring system not shown to be
extremely remote. The lithium ion battery installation must preclude
explosion in the event of those failures.
(2) Design of the lithium ion batteries must preclude the
occurrence of self-sustaining, uncontrolled increases in temperature or
pressure.
(3) No explosive or toxic gases emitted by any lithium ion battery
in normal operation or as the result of any failure of the battery
charging system, monitoring system, or battery installation which is
not shown to be extremely remote may accumulate in hazardous quantities
within the airplane.
(4) Installations of lithium ion batteries must meet the
requirements of 14 CFR 25.863(a) through (d).
(5) No corrosive fluids or gases that may escape from any lithium
ion battery may damage surrounding structure or any adjacent systems,
equipment, or electrical wiring of the airplane in such a way as to
cause a major or more severe failure condition, in accordance with 14
CFR 25.1309 (b) and applicable regulatory guidance.
(6) Each lithium ion battery installation must have provisions to
prevent any hazardous effect on structure or essential systems caused
by the maximum amount of heat the battery can generate during a short
circuit of the battery or of its individual cells.
(7) Lithium ion battery installations must have a system to control
the charging rate of the battery automatically, so as to prevent
battery overheating or overcharging, and,
(i) A battery temperature sensing and over-temperature warning
system with a means for automatically disconnecting the battery from
its charging source in the event of an over-temperature condition, or
(ii) A battery failure sensing and warning system with a means for
automatically disconnecting the battery from its charging source in the
event of battery failure.
(8) Any lithium ion battery installation whose function is required
for safe operation of the airplane must incorporate a monitoring and
warning feature that will provide an indication to the appropriate
flight crewmembers whenever the state-of-charge of the batteries has
fallen below levels considered acceptable for dispatch of the airplane.
(9) The Instructions for Continued Airworthiness required by 14 CFR
25.1529 must contain maintenance requirements to assure that the
lithium ion battery is sufficiently charged at appropriate intervals
specified by the battery manufacturer to ensure that batteries whose
function is required for safe operation of the airplane will not
degrade below specified ampere-hour levels sufficient to power the
electronic flight bag (EFB) applications that are required for
continued safe flight and landing. The Instructions for Continued
Airworthiness must also contain procedures for the maintenance of
lithium ion batteries in spares storage to prevent the replacement of
batteries whose function is required for safe operation of the airplane
with batteries that have experienced degraded charge retention ability
or other damage due to prolonged storage at a low state of charge.
Precautions should be included in the Instructions for Continued
Airworthiness maintenance instructions to prevent mishandling of the
lithium ion battery which could result in short-circuit or other
unintentional damage that could result in personal injury or property
damage.
Note 1: The term, ``sufficiently charged'' means the charge that
is applied to rechargeable lithium ion batteries, which diminishes
during the life of batteries with respect to the retentive capacity
of the batteries to deliver available power--where capacity is the
total quantity of electricity of a cell or battery, expressed in
ampere-hours. Battery life is influenced by its internal chemical
reaction and by other factors, such as temperature, shock, the
number of recharges, etc.
Note 2: These special conditions are not intended to replace 14
CFR 25.1353(c), Amendment 25-113 in the certification basis of the
ABX, Air Inc supplemental type certificate. These special conditions
apply only to lithium ion batteries and their installations. The
requirements of 14 CFR 25.1353(c), Amendment 25-113 remain in effect
for batteries and battery installations on the ABX Air supplemental
type certificate that do not use lithium ion batteries.
Compliance with the requirements of this Special Condition must be
shown by test or analysis, with the concurrence of the Chicago Aircraft
Certification Office.
