SUPPLEMENTARY INFORMATION: 

Future Requests for Installation of NonRechargeable Lithium Batteries 

The FAA anticipates that nonrechargeable lithium batteries will be 

installed in most makes and models of 

transport category airplanes. We intend 

to require special conditions for 

certification projects involving nonrechargeable lithium battery 

installations to address certain safety 

issues until we can revise the 

airworthiness requirements. Applying 

special conditions to these installations 

across the range of transport category 

airplanes will ensure regulatory 

consistency. 

Typically, the FAA issues special 

conditions after receiving an application 

for type certificate approval of a novel 

or unusual design feature. However, the 

FAA has found that the presence of nonrechargeable lithium batteries in 

certification projects is not always 


sradovich on DSK3GMQ082PROD with RULES
Federal Register / Vol. 83, No. 12 / Thursday, January 18, 2018 / Rules and Regulations 2533 

immediately identifiable, since the 

battery itself may not be the focus of the 

project. Meanwhile, the inclusion of 

these batteries has become virtually 

ubiquitous on in-production transport 

category airplanes, which shows that 

there will be a need for these special 

conditions. Also, delaying the issuance 

of special conditions until after each 

design application is received could 

lead to costly certification delays. 

Therefore, the FAA finds it necessary to 

issue special conditions applicable to 

these battery installations on particular 

makes and models of aircraft. 

On April 22, 2016, the FAA published 

special conditions no. 25–612–SC in the 

Federal Register (81 FR 23573) 

applicable to Gulfstream Aerospace 

Corporation for the GVI airplane. Those 

were the first special conditions the 

FAA issued for non-rechargeable 

lithium battery installations. We 

explained in that document our 

decision to make those special 

conditions effective one year after 

publication in the Federal Register, 

which is April 22, 2017. In those special 

conditions, the FAA stated its intention 

to apply non-rechargeable lithium 

battery special conditions to design 

changes on other makes and models 

applied for after this same date. 

Section 1205 of the FAA 

Reauthorization Act of 1996 requires the 

FAA to consider the extent to which 

Alaska is not served by transportation 

modes other than aviation and to 

establish appropriate regulatory 

distinctions when modifying 

airworthiness regulations that affect 

intrastate aviation in Alaska. In 

consideration of this requirement and 

the overall impact on safety, the FAA 

does not intend to require nonrechargeable lithium battery special 

conditions for design changes that only 

replace a 121.5 megahertz (MHz) 

emergency locator transmitter (ELT) 

with a 406 MHz ELT that meets 

Technical Standard Order C126b, or 

later revision, on transport airplanes 

operating only in Alaska. This will 

support our efforts of encouraging 

operators in Alaska to upgrade to a 406 

MHz ELT. These ELTs provide 

significantly improved accuracy for 

lifesaving services to locate an accident 

site in Alaskan terrain. The FAA 

considers that the safety benefits from 

upgrading to a 406 MHz ELT for 

Alaskan operations will outweigh the 

battery fire risk. 

Comments Invited 

The substance of these special 

conditions previously has been 

published in the Federal Register for 

public comment. These special 

conditions have 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. Therefore, the FAA 

has determined that prior public notice 

and comment are unnecessary, and 

finds that, for the same reason, good 

cause exists for adopting these special 

conditions upon publication in the 

Federal Register. 

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 comment described above. We invite 

interested people to take part in this 

rulemaking by sending written 

comments, data, or views. The most 

helpful comments reference a specific 

portion of the special conditions, 

explain the reason for any 

recommended change, and include 

supporting data. 

We will consider all comments we 

receive by the closing date for 

comments. We may change these special 

conditions based on the comments we 

receive. 

Background 

Dassault holds type certificate no. 

A50NM, which provides the 

certification basis for the Model Falcon 

2000EX airplane. The Model Falcon 

2000EX airplane is a twin engine, 

transport category airplane with a 

passenger seating capacity of 19 and a 

maximum takeoff weight of 40,700 to 

42,800 pounds, depending on the 

specific design. 

The FAA is issuing these special 

conditions for non-rechargeable lithium 

battery installations on the Dassault 

Model Falcon 2000EX airplane. The 

current battery requirements in title 14, 

Code of Federal Regulations (14 CFR) 

part 25 are inadequate for addressing an 

airplane with non-rechargeable lithium 

batteries. 

Type Certification Basis 

Under the provisions of 14 CFR 

21.101, Dassault must show that the 

Model Falcon 2000EX airplane meets 

the applicable provisions of the 

regulations listed in type certificate no. 

A50NM or the applicable regulations in 

effect on the date of application for the 

change, except for earlier amendments 

as agreed upon by the FAA. In addition, 

the certification basis includes certain 

special conditions, exemptions, or later 

amended sections that are not relevant 

to these special conditions. 

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 Dassault Model Falcon 2000EX 

airplane because of a novel or unusual 

design feature, special conditions are 

prescribed under the provisions of 

§ 21.16. 

Special conditions are initially 

applicable to the airplane 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, or should any other 

model already included on the same 

type certificate be modified to 

incorporate the same novel or unusual 

design feature, these special conditions 

would also apply to the other model 

under § 21.101. 

In addition to the applicable 

airworthiness regulations and special 

conditions, the Dassault Model Falcon 

2000EX airplane 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, in accordance 

with § 11.38, and they become part of 

the type certification basis under 

§ 21.101. 

Novel or Unusual Design Feature 

The novel or unusual design feature is 

the installation of non-rechargeable 

lithium batteries. 

For the purpose of these special 

conditions, we refer to a battery and 

battery system as a battery. A battery 

system consists of the battery and any 

protective, monitoring, and alerting 

circuitry or hardware inside or outside 

of the battery. It also includes vents 

(where necessary) and packaging. 

Discussion 

The FAA derived the current 

regulations governing installation of 

batteries in transport category airplanes 

from Civil Air Regulations (CAR) 

4b.625(d) as part of the recodification of 

CAR 4b that established 14 CFR part 25 

in February 1965. This recodification 

basically reworded the CAR 4b battery 

requirements, which are currently in 

§ 25.1353(b)(1) through (4). Nonrechargeable lithium batteries are novel 

and unusual with respect to the state of 

technology considered when these 

requirements were codified. These 

batteries introduce higher energy levels 

into airplane systems through new 

chemical compositions in various 

battery cell sizes and construction. 

Interconnection of these cells in battery 

packs introduces failure modes that 

require unique design considerations, 


sradovich on DSK3GMQ082PROD with RULES
2534 Federal Register / Vol. 83, No. 12 / Thursday, January 18, 2018 / Rules and Regulations 

such as provisions for thermal 

management. 

Recent events involving rechargeable 

and non-rechargeable lithium batteries 

prompted the FAA to initiate a broad 

evaluation of these energy storage 

technologies. In January 2013, two 

independent events involving 

rechargeable lithium-ion batteries 

revealed unanticipated failure modes. A 

National Transportation Safety Board 

(NTSB) letter to the FAA, dated May 22, 

2014, which is available at http://

www.ntsb.gov, filename A–14–032– 

036.pdf, describes these events. 

On July 12, 2013, an event involving 

a non-rechargeable lithium battery in an 

emergency locator transmitter 

installation demonstrated unanticipated 

failure modes. The United Kingdom’s 

Air Accidents Investigation Branch 

Bulletin S5/2013 describes this event. 

Some known uses of rechargeable and 

non-rechargeable lithium batteries on 

airplanes include: 

• Flight deck and avionics systems 

such as displays, global positioning 

systems, cockpit voice recorders, flight 

data recorders, underwater locator 

beacons, navigation computers, 

integrated avionics computers, satellite 

network and communication systems, 

communication management units, and 

remote-monitor electronic linereplaceable units; 

• Cabin safety, entertainment, and 

communications equipment, including 

emergency locator transmitters, life 

rafts, escape slides, seatbelt air bags, 

cabin management systems, Ethernet 

switches, routers and media servers, 

wireless systems, internet and in-flight 

entertainment systems, satellite 

televisions, remotes, and handsets; 

• Systems in cargo areas including 

door controls, sensors, video 

surveillance equipment, and security 

systems. 

Some known potential hazards and 

failure modes associated with nonrechargeable lithium batteries are: 

• Internal failures: In general, these 

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. The metallic 

lithium can ignite, resulting in a selfsustaining fire or explosion. 

• Fast or imbalanced discharging: 

Fast discharging or an imbalanced 

discharge of one cell of a multi-cell 

battery may create an overheating 

condition that results in an 

uncontrollable venting condition, which 

in turn leads to a thermal event or an 

explosion. 

• Flammability: Unlike nickelcadmium and lead-acid batteries, 

lithium batteries use higher energy and 

current in an electrochemical system 

that can be configured to maximize 

energy storage of lithium. They also use 

liquid electrolytes that can be extremely 

flammable. The electrolyte, as well as 

the electrodes, can serve as a source of 

fuel for an external fire if the battery 

casing is breached. 

Special condition no. 1 of these 

special conditions requires that each 

individual cell within a nonrechargeable lithium battery be designed 

to maintain safe temperatures and 

pressures. Special condition no. 2 

addresses these same issues but for the 

entire battery. Special condition no. 2 

requires the battery be designed to 

prevent propagation of a thermal event, 

such as self-sustained, uncontrollable 

increases in temperature or pressure 

from one cell to adjacent cells. 

Special conditions nos. 1 and 2 are 

intended to ensure that the nonrechargeable lithium battery and its 

cells are designed to eliminate the 

potential for uncontrollable failures. 

However, a certain number of failures 

will occur due to various factors beyond 

the control of the battery designer. 

Therefore, other special conditions are 

intended to protect the airplane and its 

occupants if failure occurs. 

Special conditions 3, 7, and 8 are selfexplanatory. 

Special condition no. 4 makes it clear 

that the flammable fluid fire protection 

requirements of § 25.863 apply to nonrechargeable lithium battery 

installations. Section 25.863 is 

applicable to areas of the airplane that 

could be exposed to flammable fluid 

leakage from airplane systems. Nonrechargeable lithium batteries contain 

an electrolyte that is a flammable fluid. 

Special condition no. 5 requires that 

each non-rechargeable lithium battery 

installation not damage surrounding 

structure or adjacent systems, 

equipment, or electrical wiring from 

corrosive fluids or gases that may escape 

in such a way as to cause a major or 

more severe failure condition. 

While special condition no. 5 

addresses corrosive fluids and gases, 

special condition no. 6 addresses heat. 

Special condition no. 6 requires that 

each non-rechargeable lithium battery 

installation have provisions to prevent 

any hazardous effect on airplane 

structure or systems caused by the 

maximum amount of heat the battery 

installation can generate due to any 

failure of it or its individual cells. The 

means of meeting special conditions 

nos. 5 and 6 may be the same, but the 

requirements are independent and 

address different hazards. 

These special conditions apply to all 

non-rechargeable lithium battery 

installations in lieu of § 25.1353(b)(1) 

through (4) at Amendment 25–123 or 

§ 25.1353(c)(1) through (4) at earlier 

amendments. Those regulations remain 

in effect for other battery installations. 

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. 

Applicability 

These special conditions are 

applicable to the Dassault Model Falcon 

2000EX airplane. Should Dassault apply 

at a later date for a change to the type 

certificate to include another model 

incorporating the same novel or unusual 

design feature, these special conditions 

would apply to that model as well. 

These special conditions are only 

applicable to design changes applied for 

after the effective date. 

These special conditions are not 

applicable to changes to previously 

certified non-rechargeable lithium 

battery installations where the only 

change is either cosmetic or to relocate 

the installation to improve the safety of 

the airplane and occupants. Previously 

certified non-rechargeable lithium 

battery installations, as used in this 

paragraph, are those installations 

approved for certification projects 

applied for on or before the effective 

date of these special conditions. A 

cosmetic change is a change in 

appearance only, and does not change 

any function or safety characteristic of 

the battery installation. These special 

conditions are also not applicable to 

unchanged, previously certified nonrechargeable lithium battery 

installations that are affected by a 

change in a manner that improves the 

safety of its installation. The FAA 

determined that these exclusions are in 

the public interest because the need to 

meet all of the special conditions might 

otherwise deter these design changes 

that improve safety. 

Conclusion 

This action affects only certain a 

novel or unusual design feature on one 

model of airplane. It is not a rule of 

general applicability.

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

Subtitle I, Section 106 describes the 

authority of the FAA Administrator. 

Subtitle VII, Aviation Programs, 

describes in more detail the scope of the 

agency’s authority. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it amends 

Class E airspace extending upward from 

700 feet above the surface at Northeast 

Iowa Regional Airport, Charles City, IA, 

to support IFR operations at this airport. 

History 

The FAA published a notice of 

proposed rulemaking in the Federal 

Register (82 FR 48010; October 16, 

2017) for Docket No. FAA–2017–0949 to 

modify Class E airspace extending 

upward from 700 feet above the surface 

at Northeast Iowa Regional Airport, 

Charles City, IA. Interested parties were 

invited to participate in this rulemaking 

effort by submitting written comments 

on the proposal to the FAA. No 

comments were received. 

Class E airspace designations are 

published in paragraph 6005 of FAA 

Order 7400.11B, dated August 3, 2017, 

and effective September 15, 2017, which 

is incorporated by reference in 14 CFR 

71.1. The Class E airspace designations 

listed in this document will be 

published subsequently in the Order.
