### 52109 Federal Register / Vol. 78, No. 163 / Thursday, August 22, 2013 / Proposed Rules

series airplanes modified by the ARINC Aerospace Company.

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 the Boeing Model 777–200, –300, and –300ER series airplanes are addressed, and (2) appropriate instructions for continued airworthiness, which include maintenance requirements, are established to ensure the availability of electrical power from the batteries when
needed.

In lieu of the requirements of 14 CFR 25.1353(b)(1) through (b)(4) at Amendment 25–113, the following special conditions apply. Rechargeable lithium ion batteries and battery systems on Boeing Model 777–200, –300, and –300ER series 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 ion batteries and battery systems must preclude explosion in the
event of those failures.

(2) Design of the 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 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 lithium ion batteries and battery systems must meet the requirements of § 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 § 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) Lithium ion batteries and battery systems 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 and battery system 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-ofcharge of the batteries has fallen below levels considered acceptable for dispatch of the airplane.

(9) The instructions for continued airworthiness required by § 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. 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 that could to 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 there is 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 § 25.1353(b) at
Amendment 25–113 in the certification basis of Boeing Model 777–200, –300, and–300ER series airplanes. These special conditions apply only to rechargeable lithium ion batteries and battery systems and their installations. The requirements of § 25.1353(b) at Amendment 25–113 remain in effect for batteries and battery installations on Boeing Model 777–200, –300, and –300ER series airplanes that do not use rechargeable
lithium ion batteries.

Persons interested in being placed on a mailing list for future NPRM’s should contact the FAA’s Office of Rulemaking, (202) 267–9677, to request a copy of Advisory circular No. 11–2A, Notice of Proposed Rulemaking distribution System, which describes the application procedure.

The Proposal

The FAA is considering an amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 to amend Class D and Class E airspace at Salisbury-Ocean City Wicomico Regional Airport, Salisbury, MD. Class D airspace and Class E surface area airspace would be amended to within a 4.3-mile radius of the airport. Class E airspace extending upward from 700
feet above the surface would be
amended to within a 7-mile radius of the airport. Class E airspace designated
as an extension to a Class D surface area airspace would be established within a 4.3-mile radius of the airport, with segments extending 7 miles southeast, northeast, and southwest of the airport. The geographic coordinates of the airport also would be adjusted to
coincide with the FAA’s aeronautical database. The Class D city designation would be changed from Salisbury-Ocean City Wicomico Regional Airport, MD, to Salisbury, MD.

Class D airspace and Class E airspace designations are published in Paragraph 5000, 6002, 6004, and 6005 respectively, of FAA Order 7400.9W, dated August 8, 2012, and effective September 15, 2012, which is incorporated by reference in 14
CFR 71.1. The Class D and Class E airspace designation listed in this document will be published subsequently in the Order.

The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore, (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a Regulatory Evaluation as the anticipated impact is so minimal.
Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this proposed rule, when promulgated, would not have a significant economic impact on a substantial number of small
entities under the criteria of the Regulatory Flexibility Act.

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 proposed 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 proposed regulation is within the scope of that authority as it would amend Class D and E airspace at Salisbury-Ocean City Wicomico Regional Airport, Salisbury, MD.

This proposal will be subject to an environmental analysis in accordance with FAA Order 1050.1E, ‘‘Environmental Impacts: Policies and Procedures’’ prior to any FAA final regulatory action.
