Installed Rechargeable Lithium-Ion Batteries and Battery Systems

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed special conditions.

-----------------------------------------------------------------------

SUMMARY: This action proposes special conditions for Airbus Model A350-
900 series airplanes. These airplanes will have a novel or unusual
design feature associated with permanently installed rechargeable
lithium-ion batteries and battery systems. These batteries have 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 applicable airworthiness regulations
do not contain adequate or appropriate safety standards for this design
feature. These proposed 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.

Background

    On August 25, 2008, Airbus applied for a type certificate for their
new Model A350-900 series airplane. Later, Airbus requested, and the
FAA approved, an extension to the application for FAA type
certification to June 28, 2009. The Model A350-900 series has a
conventional layout with twin wing-mounted Rolls-Royce Trent XWB
engines. It features a twin aisle, 9-abreast, economy-class layout, and
accommodates side-by-side placement of LD-3 containers in the cargo
compartment. The basic Model A350-900 series configuration accommodates
315 passengers in a standard two-class arrangement. The design cruise
speed is Mach 0.85 with a maximum take-off weight of 602,000 lbs.
Airbus proposes the Model A350-900 series to be certified for extended
operations (ETOPS) beyond 180 minutes at entry into service for up to a
420-minute maximum diversion time.
    Existing airworthiness regulations did not anticipate the use of
lithium-ion batteries and battery systems on aircraft. Lithium-ion
batteries and battery systems have new hazards that were not
contemplated when the existing regulations were issued. In Title 14,
Code of Federal Regulations (14 CFR) 25.1353, the FAA provided an
airworthiness standard for lead-acid batteries and nickel-cadmium
batteries. These special conditions provide an equivalent level of
safety as that of the existing regulation. The current regulations are
not adequate for rechargeable lithium-battery and battery system
installations. Additional lithium-battery and battery system special
conditions are required to ensure the same level of safety as set forth
by the existing regulation intended for other battery technology.

Type Certification Basis

    Under the provisions of 14 CFR 21.17, Airbus must show that the
Model A350-900 series meets the applicable provisions of 14 CFR part
25, as amended by Amendments 25-1 through 25-128.
    The FAA has determined that Airbus Model A350-900 series airplanes
must comply with the following sections: Sec.  25.863(a) through (d),
Amendment 25-61 and Amendment 25-66.
    If the Administrator finds that the applicable airworthiness
regulations (i.e., 14 CFR part 25) do not contain adequate or
appropriate safety standards for the Model A350-900 series because of a
novel or unusual design feature, special conditions are prescribed
under Sec.  21.16.
    Special conditions are initially applicable to the model or series
for which they are issued. Should the type certificate for that model
be amended later to include any other model that incorporates the same
or similar novel or unusual design feature, the special conditions
would also apply to the other model under Sec.  21.101.
    In addition to the applicable airworthiness regulations and special
conditions, the Airbus Model A350-900 airplane must comply with the
fuel-vent and exhaust-emission requirements of 14 CFR part 34, the
noise-certification requirements of 14 CFR part 36, and the FAA must
issue a finding of regulatory adequacy under Sec.  611 of Public Law
92-574, the ``Noise Control Act of 1972.''
    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.  21.17(a)(2).

Novel or Unusual Design Features

    The Airbus Model A350-900 airplane will incorporate the following
novel or unusual design features: permanently installed rechargeable
lithium batteries and lithium battery systems.

Discussion

    The current regulations governing installation of batteries in
large transport-category airplanes were derived from Civil Air
Regulations (CAR) part 4b.625(d) as part of the re-codification of CAR
4b that established 14 CFR part 25 in February 1965. The new battery
requirements, Sec.  25.1353(c)(1) through (c)(4), basically reworded
the CAR requirements.
    Increased use of nickel-cadmium batteries in small airplanes
resulted in increased incidents of battery fires and failures which led
to additional rulemaking affecting large transport-category airplanes
as well as small airplanes. On September 1, 1977 and March 1, 1978, the
FAA issued Sec.  25.1353(c)(5) and (c)(6), respectively, governing
nickel-cadmium battery installations on large transport-category
airplanes.
    The proposed use of lithium-ion batteries and battery systems for
equipment and systems on Airbus Model A350 airplanes has prompted the
FAA to review the adequacy of these existing regulations. Our review
indicates that the existing regulations do not adequately address
several failure, operational, and maintenance characteristics of
lithium-ion batteries and battery systems that could affect the safety
and reliability of the Airbus model A350-900 airplane rechargeable
lithium batteries and rechargeable lithium-battery-system
installations.
    At present, commercial aviation has limited experience with use of
rechargeable lithium-ion batteries and battery systems in applications
involving commercial aviation. However, other users of this technology,
ranging from wireless telephone manufacturers to the electric-vehicle
industry, have noted potential hazards with lithium-ion batteries and
battery systems. These problems include overcharging, over-discharging,
and flammability of cell components.

1. Overcharging

    In general, lithium-ion batteries and battery systems 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
condition is especially true for overcharging, which 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 and battery
systems, 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
flightcrews 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 and battery systems 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.
    The problems lithium-ion battery and battery-system users
experience raise concern about the use of these batteries in commercial
aviation. The intent of the proposed special conditions is to establish
appropriate airworthiness standards for lithium-ion battery
installations in Airbus Model A350-900 airplanes and to ensure, as
required by Sec. Sec.  25.1309 and 25.601, that these lithium-ion
batteries and battery systems will not result in an unsafe condition.
To address these concerns, these special conditions adopt the following
requirements:
     Those sections of 14 CFR 25.1353 that are applicable to
lithium ion batteries.
     The flammable fluid fire protection requirements of 14 CFR
25.863. In the past, this rule 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 ion batteries.
     New maintenance requirements to ensure that batteries used
as spares are maintained in an appropriate state of charge.
    These special conditions are similar to lithium-ion batteries and
battery systems special conditions adopted for the Boeing Model 787 (72
FR 57842; October 11, 2007).

Applicability

    As discussed above, these special conditions are applicable to the
Airbus Model A350-900 series airplanes. Should Airbus 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.

Conclusion

    This action affects only certain novel or unusual design features
on Airbus Model A350-900 series airplanes. It is not a rule of general
applicability.

List of Subjects in 14 CFR Part 25

    Aircraft, Aviation safety, Reporting and recordkeeping
requirements.

    The authority citation for these special conditions is as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701, 44702, 44704.

The Proposed Special Conditions

    Accordingly, the Federal Aviation Administration (FAA) proposes the
following special conditions as part of the type certification basis
for Airbus Model A350-900 airplanes.
    These proposed special conditions require that (1) all
characteristics of the rechargeable lithium-ion batteries and battery
systems, and their installation, that could affect safe operation of
Airbus Model A350-900 airplanes, are addressed, and (2) appropriate
Instructions for Continued Airworthiness, which include maintenance
requirements, are established to ensure the availability of electrical
power, when needed, from the batteries.
    The FAA proposes that the following special conditions apply to all
rechargeable lithium-ion batteries and battery systems on Airbus Model
A350-900 airplanes, in lieu of the requirements of Sec.  25.1353(b)(1)
through (b)(4) at Amendment 25-113:
    Rechargeable lithium-ion batteries and battery systems on Airbus
Model A350-900 airplanes must be designed and installed as follows:
    1. Safe cell temperatures and pressures must be maintained during
any foreseeable charging or discharging condition, and during any
failure of the charging or battery monitoring system not shown to be
extremely remote. The rechargeable lithium-ion batteries and battery
systems must preclude explosion in the event of those failures.
    2. Design of the rechargeable lithium-ion batteries and battery
systems must preclude the occurrence of self-sustaining, uncontrolled
increases in temperature or pressure.
    3. No explosive or toxic gases emitted by any rechargeable lithium-
ion batteries and battery systems in normal operation, or as the result
of any failure of the battery charging system, monitoring system, or
battery installation that is not shown to be extremely remote, may
accumulate in hazardous quantities within the airplane.
    4. Installations of rechargeable lithium-ion batteries and battery
systems must meet the requirements of Sec.  25.863(a) through (d).
    5. No corrosive fluids or gases that may escape from any lithium-
ion batteries and battery systems 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 Sec.  25.1309 (b) and applicable regulatory guidance.
    6. Each lithium-ion battery and battery system 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. Rechargeable lithium-ion batteries and battery systems must have
a system to automatically control the charging rate of the battery, 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 rechargeable lithium-ion batteries and battery systems, the
function of which are 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 Sec.
25.1529 must contain maintenance requirements to assure that the
lithium-ion batteries are sufficiently charged at appropriate intervals
specified by the battery manufacturer and the equipment manufacturer of
the rechargeable lithium-ion battery or rechargeable lithium-ion
battery system. This is required to ensure that rechargeable lithium-
ion batteries and battery systems will not degrade below specified
ampere-hour levels sufficient to power the aircraft system, for
intended applications. The Instructions for Continued Airworthiness
must also contain procedures for the maintenance of batteries in spares
storage to prevent

the replacement of batteries with batteries that have experienced
degraded charge-retention ability or other damage due to prolonged
storage at a low state of charge. Replacement batteries must be of the
same manufacturer and part number as approved by the FAA. Precautions
should be included in the Instructions for Continued Airworthiness
maintenance instructions to prevent mishandling of the rechargeable
lithium-ion batteries and battery systems, which could result in short-
circuit or other unintentional impact damage caused by dropping or
other destructive means.

    Note 1: The term ``sufficiently charged'' means that the battery
will retain enough of a charge, expressed in ampere-hours, to ensure
that the battery cells will not be damaged. A battery cell may be
damaged by lowering the charge below a point where the battery
experiences a reduction in the ability to charge and retain a full
charge. This reduction would be greater than the reduction that may
result from normal operational degradation.

    Note 2: These special conditions are not intended to replace
Sec.  25.1353(b) at Amendment 25-113 in the certification basis for
Airbus Model A350-900 airplanes. These special conditions apply only
to rechargeable lithium-ion batteries and battery systems and their
installations. The requirements of Sec.  25.1353(b) at Amendment 25-
113 remain in effect for batteries and battery installations on
Airbus Model A350-900 airplanes that do not use rechargeable
lithium-ion batteries.

Alexander Drive, P.O. Box 12014, Research Triangle Park, NC 27709,
requests to establish a tolerance in 40 CFR part 180 for residues of
the fungicide, trifloxystrobin (benzeneacetic acid, (E,E)-[alpha]-
(methoxyimino)-2-[[[[1-[3-(trifluoromethyl)
phenyl]ethylidene]amino]oxy]methyl]-methyl ester) and the free form of
its acid metabolite CGA-321113 ((E,E)-methoxyimino-[2-[1-(3-
trifluoromethyl-phenyl)-ethylideneaminooxymethyl]-phenyl]acetic acid)
in or on dried shelled pea and bean (except soybean) subgroup 6C at
0.06 parts per million (ppm). The analytical method involves solvent
mixtures and solvent to matrix ratio, deuterated internal standards,
and Liquid Chromatography/Mass Spectrometry-Mass Spectrometry (LC/MS-
MS) with an electrospray interface, operated in the positive ion mode.
Residues of trifloxystrobin are quantified by high-pressure liquid
chromatography/triple stage quadrupole mass spectrometry (LC/MS/MS)
using stable-labeled internal standards. Contact: RD.
