Farm Credit Administration Board 

Meetings; Sunshine Act 

AGENCY: Farm Credit Administration. 

ACTION: Direct final rule. 

SUMMARY: The Farm Credit 

Administration (FCA or we) issues this 

direct final rule amending our 

regulation on meeting announcements 

to provide greater flexibility to the FCA 

Board in scheduling meetings. 

DATES: The regulation shall become 

effective upon the expiration of 30 days 

after publication in the Federal Register 

during which either or both Houses of 

Congress are in session. We will publish 

notice of the effective date in the 

Federal Register.

SUPPLEMENTARY INFORMATION: The Farm 

Credit Administration Board (Board) 

holds its regularly scheduled meeting 

on the second Thursday of each month. 

Occasionally, matters may require the 

Board to reschedule the monthly 

meeting or to hold meetings between its 

regularly scheduled monthly meetings. 

We are amending § 604.425 to provide 

the Board greater flexibility in 

rescheduling meetings or holding 

additional meetings. The current rule 

provides that the Board may fix a 

different time and place for a meeting 

only at an earlier regularly scheduled 

meeting. The new rule removes this 

constraint and allows the Board to set a 

time and place for a meeting by public 

announcement in accordance with the 

Government in the Sunshine Act, 5 

U.S.C. 552b. 

We are amending § 604.425 by a 

direct final rulemaking. Because 

§ 604.425 is a rule of agency procedure 

not requiring notice and comment (5 

U.S.C. 553(b)(A)), the amendment is 

adopted as a direct final rule without 

notice and comment. We will publish 

notice of the effective date of the rule 

following the required congressional 

waiting period under section 5.17(c)(1) 

of the Farm Credit Act of 1971, as 

amended. 

Regulatory Flexibility Act 

Pursuant to section 605(b) of the 

Regulatory Flexibility Act (5 U.S.C. 601 

et seq.), the FCA hereby certifies that 

this rule will not have a significant 

economic impact on a substantial 

number of small entities. Each of the 

banks in the System, considered 

together with its affiliated associations, 

has assets and annual income in excess 

of the amounts that would qualify them 

as small entities. Therefore, System 

institutions are not ‘‘small entities’’ as 

defined in the Regulatory Flexibility 

Act.

■ 2. Section 604.425 is revised to read 

as follows: 

§ 604.425 Announcement of Meetings. 

(a) The Board meets in the offices of 

the Farm Credit Administration, 

McLean, Virginia 22102–5090, on the 

second Thursday of each month, unless 

the Board fixes a different time and/or 

place for a meeting and follows the 

requirements of paragraph (b) of this 

section. 

(b)(1) The Farm Credit Administration 

shall make available for public 

inspection the time, place, and subject 

matter of the meeting, and whether it is 

to be open or closed, by posting notice 

on its public notice board or on its 

public Web site except to the extent that 

such information is exempt from 

disclosure under the provisions of 

§ 604.420 of this part. The public 

announcement must be made at least 1 

week before the meeting, unless a 

majority of the FCA Board determines 

by a recorded vote that agency business 

requires that a meeting be called on 

lesser notice, in which case the 

announcement shall be made at the 

earliest practicable time. 

(2) Once a meeting has been 

announced, the time, place, and subject 

matter of the meeting and whether it is 

open or closed to the public may be 

changed following the requirements of 

the Government in the Sunshine Act, 5

SUPPLEMENTARY INFORMATION: The FAA 

has determined that notice of, and 

opportunity for prior public comment 

on, these special conditions are 

impracticable because these procedures 

would significantly delay issuance of 

the design approval and thus delivery of 

the affected airplane. 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. 

Comments Invited 

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 ask that you send 

us two copies of written comments. 

We will file in the docket all 

comments we receive, as well as a 

report summarizing each substantive 

public contact with FAA personnel 

about these special conditions. You can 

inspect the docket before and after the 

comment closing date. If you wish to 

review the docket in person, go to the 

address in the ADDRESSES section of this 

preamble between 7:30 a.m. and 4 p.m., 

Monday through Friday, except Federal 

holidays. 

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. 

If you want us to acknowledge receipt 

of your comments on these special 

conditions, include with your 

comments a self-addressed, stamped 

postcard on which you have written the 

docket number. We will stamp the date 

on the postcard and mail it back to you. 

Background 

On April 15, 2008, Rosemount 

Aerospace Inc. applied for a 

supplemental type certificate for 

installation of a cargo video-surveillance 

system (CVSS) in Airbus Model A330– 

200 and A330–300 airplanes. The CVSS 

uses or otherwise incorporates lithium 

batteries. 

Existing regulations do not adequately 

address several characteristics of 

lithium batteries. Lithium-battery 

installations could affect the safety and 

reliability of the Airbus Model A330– 

200 and A330–300 airplanes. These 

special conditions address 

characteristics of, and safety measures 

required for, lithium-battery 

installations. 

Type Certification Basis 

Under the provisions of § 21.101, 

Rosemount Aerospace Inc. must show 

that the Airbus Model A330–200 and 

A330–300 airplanes, as changed, 

continue to meet the applicable 

provisions of the regulation 

incorporated by reference in Type 

Certificate No. A46NM 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 regulation 

incorporated by reference in A46NM is 

14 CFR 25.1353 at Amendment 25–38. 

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 Rosemount Aerospace Inc. CVSS 

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 Airbus Model A330–200 

and A330–300 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 34 and the noise-certification 

requirements of 14 CFR part 36; and the 

FAA must issue a finding of regulatory 

adequacy under § 611 of Public Law 92– 

574, the ‘‘Noise Control Act of 1972.’’ 

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 

§ 21.17(a)(2). 

Special conditions are initially 

applicable to the model for which they 

are issued. Should the applicant apply 

for a supplemental type certificate to 

modify any other model included on the 

same type certificate, to incorporate the 

same novel or unusual design feature, 

the special conditions would also apply 

to the other model under § 21.101. 

Novel or Unusual Design Features 

The Rosemount Aerospace Inc. 

modification to Airbus Model A330–200 

and A330–300 airplanes will 

incorporate the following novel or 

unusual design feature: a lithiumbattery system. 

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 recodification of CAR 4b that established 

14 CFR part 25 in February, 1965. The 

new battery requirements, 

§ 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, transportcategory airplanes as well as small 

airplanes. On September 1, 1977, and 

March 1, 1978, respectively, the FAA 

issued § 25.1353(c)(5) and (c)(6), 

governing nickel-cadmium battery 

installations on large, transport-category 

airplanes. 

The proposed use of lithium batteries 

for equipment and systems on the 

Airbus Model A330–200 and A330–300 

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 batteries that 

could affect the safety and reliability of 

lithium-battery installations on Airbus 

Model A330–200 and A330–300 

airplanes. 

At present, there is limited experience 

with use of rechargeable lithium 

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 batteries. 

These problems include overcharging, 


sroberts on DSKD5P82C1PROD with RULES
Federal Register / Vol. 74, No. 167 / Monday, August 31, 2009 / Rules and Regulations 44729 

over-discharging, and flammability of 

cell components. 

1. Overcharging 

In general, lithium 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, 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 

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 batteries 

use liquid electrolytes that are 

flammable. The electrolyte can serve as 

a source of fuel for an external fire if the 

battery container is breached. 

These problems, experienced by users 

of lithium batteries, raise concerns 

about the use of these batteries in 

commercial aviation. The intent of the 

proposed special conditions is to 

establish appropriate airworthiness 

standards for lithium-battery 

installations in the Airbus Model A330– 

200 and A330–300 airplanes and to 

ensure, as required by §§ 25.1309 and 

25.601, that these battery installations 

are not hazardous or unreliable. 

Applicability 

As discussed above, these special 

conditions are applicable to the 

Rosemount Aerospace Inc., cargo videosurveillance systems. Should 

Rosemount Aerospace Inc. apply at a 

later date for a supplemental type 

certificate to modify any other model 

included on Type Certificate No. 

A46NW, to incorporate 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 

Rosemount Aerospace Inc. CSVVs 

installed on Airbus Model A330–200 

and A330–300 airplanes. It is not a rule 

of general applicability and affects only 

the applicant who 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. Therefore, 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 

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 

comment described above.

special conditions is as follows: 

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

44702, 44704. 

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 Airbus Model 

A330–200 and A330–300 airplanes 

modified by Rosemount Aerospace Inc. 

lithium batteries, and battery 

installations on Airbus Model A330–200 

and A330–300 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 

lithium-battery installation must 

preclude explosion in the event of those 

failures. 

2. Design of the lithium batteries must 

preclude the occurrence of selfsustaining, uncontrolled increases in 

temperature or pressure. 

3. No explosive or toxic gases, emitted 

by any lithium 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 batteries 

must meet the requirements of 

§ 25.863(a) through (d). 

5. No corrosive fluids or gases that 

may escape from any lithium 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 

§ 25.1309 (b) and applicable regulatory 

guidance. 

6. Each lithium-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-battery installations must 

have a system to automatically control 

the charging rate of the battery, to 

prevent battery overheating or 

overcharging, and, 

a. 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, 

b. A battery-failure-sensing-andwarning system with a means for 

automatically disconnecting the battery 

from its charging source in the event of 

battery failure. 

8. Any lithium-battery installation, 

the function of which is required for 

safe operation of the airplane, must 

incorporate a monitoring-and-warning 

feature that provides an indication to 

the appropriate flight-crew members 

when the state-of-charge of the batteries 

has fallen below levels considered 

acceptable for dispatch of the airplane. 

9. The instructions for continued 

airworthiness (ICA), required by 

§ 25.1529 (and 26.11), must contain 

maintenance steps to: 

a. Assure that the lithium battery is 

sufficiently charged at appropriate 

intervals specified by the battery 

manufacturer. 

b. Ensure the integrity of lithium 

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 


sroberts on DSKD5P82C1PROD with RULES
44730 Federal Register / Vol. 74, No. 167 / Monday, August 31, 2009 / Rules and Regulations 

prolonged storage at a low state of 

charge. 

The ICA maintenance procedures must 

contain precautions to prevent 

mishandling of the lithium battery, 

which could result in short-circuit or 

other unintentional damage that, in 

turn, could result in personal injury or 

property damage. 

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’s ability to charge and retain a full 

charge is reduced. 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 § 25.1353(b) in the 

certification basis of the Airbus Model A330– 

200 and A330–300 airplanes. These special 

conditions apply only to lithium batteries 

and their installations. The requirements of 

§ 25.1353(b) remain in effect for batteries and 

battery installations in Airbus Model A330– 

200 and A330–300 airplanes that do not use 

lithium batteries. 

Compliance with the requirements of 

these special conditions must be shown 

by test, or analysis by the Aircraft 

Certification Office or its designees, 

with the concurrence of the FAA 

Transport Airplane Directorate.

Background 

On July 1, 2008, Bombardier Inc. 400 

Cote Vertu West, Dorval, Quebec, 

Canada, H4S 1Y9 applied for a design 

change to Type Certificate No. A21EA 

for installation of seats that include nontraditional, large, non-metallic panels in 

the following Bombardier Inc. airplanes: 

Model CL–600–2B19, Model CL–600– 

2C10, Model CL–600–2D15 and Model 

CL–600–2D24. These airplanes, which 

are currently approved under Type 

Certificate No. A21EA, are swept-wing, 

T-tail, twin-engine, fuselage mounted 

turbofan-powered, single aisle, medium 

sized transport category airplanes. 

The applicable regulations to 

airplanes currently approved under 

Type Certificate No. A21EA do not 

require seats to meet the more stringent 

flammability standards required of 

large, non-metallic panels in the cabin 

interior. At the time the applicable rules 

were written, seats were designed with 

a metal frame covered by fabric, not 

with large, non-metallic panels. Seats 

also met the then recently adopted 

standards for flammability of seat 

cushions. With the seat design being 

mostly fabric and metal, the 

contribution to a fire in the cabin had 

been minimized and was not considered 

a threat. For these reasons, seats did not 

need to be tested to heat release and 

smoke emission requirements. 

Seat designs have now evolved to 

occasionally include non-traditional, 

large, non-metallic panels. Taken in 

total, the surface area of these panels is 

on the same order as the sidewall and 

overhead stowage bin interior panels. 

To provide the level of passenger 

protection intended by the 

airworthiness standards, these nontraditional, large, non-metallic panels in 

the cabin must meet the standards of 

Title 14 Code of Federal Regulations (14 

CFR), part 25, Appendix F, parts IV and 

V, heat release and smoke emission 

requirements. 

Type Certification Basis 

Under the provisions of § 21.101 

Bombardier must show that the 

following airplane models, CL–600– 

2B19, CL–600–2C10, CL–600–2D15 and 

CL–600–2D24, as changed, continue to 

meet the applicable provisions of the 

regulations incorporated by reference in 

Type Certificate No. A21AE, 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 regulations incorporated by 

reference in Type Certificate No. A21AE 

are for the following models: 

• CL–600–2B19, part 25, effective 

February 1, 1965, including 

Amendments 25–1 through 25–62; 

• CL–600–2C10, part 25, effective 

February 1, 1965, including 

Amendments 25–1 through 25–86: 

• CL–600–2D15, part 25, effective 

February 1, 1965, including 

Amendments 25–1 through 25–86, 

Amendments 25–88 through 

Amendments 25–90 and Amendments 

25–92 through Amendments 25–98. 

• CL–600–2D24, part 25, effective 

February 1, 1965, including 

Amendments 25–1 through 25–86,
