SUPPLEMENTARY INFORMATION: The FAA has determined that notice of, and opportunity for prior public comment on, these special conditions is impracticable because these procedures would significantly delay issuance of the design approval and thus delivery of the affected aircraft. 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 publication in the Federal Register. 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 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 On January 13, 2014, Universal Avionics Systems Corporation applied for a supplemental type certificate (STC) for the installation of Universal Avionics InSightTM EFIS, EIU, UNS-1Fw WAAS FMS, and TAWS Class A, which will use rechargeable lithium batteries and battery systems. The Cessna, Model 650, Citation VII is a pressurized, two-crew, seven-passenger, low wing transport with two aft mounted turbo-fan engines. Rechargeable lithium 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 transport category airplanes. Type Certification Basis Under the provisions of Sec. 21.101, Universal Avionics Systems Corporation must show that the Cessna, Model 650, Citation VII, as changed, continues to meet the applicable provisions of the regulations listed in Type Certificate No. A9NM or the applicable regulations in effect on the date of application for the change except for earlier amendments as [[Page 11320]] agreed upon by the FAA. The regulations listed in the type certificate are commonly referred to as the ``original type-certification basis.'' In addition, if the regulations listed do not provide adequate standards regarding the change, the applicant must comply with certain regulations in effect on the date of application for the change. 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 Cessna, Model 650, Citation VII airplane because of a novel or unusual design feature, special conditions are prescribed under the provisions of Sec. 21.16. Special conditions are initially applicable to the model for which they are issued. Should the applicant apply for a supplemental type certificate (STC) to modify any other model included on the same type certificate to incorporate the same or similar novel or unusual design feature, these special conditions would also apply to the other model under Sec. 21.101. In addition to the applicable airworthiness regulations and special conditions, the Cessna, Model 650, Citation VII 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 Sec. 11.38, and they become part of the type- certification basis under Sec. 21.101. Novel or Unusual Design Features The Cessna, Model 650, Citation VII will incorporate the following novel or unusual design feature: The installation of a Universal Avionics InSightTM EFIS, EIU, UNS-1Fw WAAS FMS, and TAWS Class A, which will use rechargeable lithium batteries and 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), reworded the CAR requirements. Increased use of nickel-cadmium batteries in small airplanes resulted in increased incidents of battery fires and failures that 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 rechargeable lithium batteries for equipment and systems 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 rechargeable lithium batteries that could affect the safety and reliability of the Cessna, Model 650, Citation VII airplane lithium battery installations. At present, there is limited experience with the use of rechargeable lithium 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 safety problems with rechargeable lithium batteries. These problems include overcharging, over-discharging, and flammability of cell components. 1. Overcharging In general, lithium 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 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 battery cells 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 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 batteries raise concern about the use of these batteries in commercial aviation. The intent of the special conditions are to establish appropriate airworthiness standards for lithium battery installations in the Cessna, Model 650, Citation VII airplane and to ensure, as required by Sec. Sec. 25.1309 and 25.601, that these batteries are not hazardous or unreliable. 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 As discussed above, these special conditions are applicable to the Cessna, Model 650, Citation VII airplane. Should Universal Avionics Systems Corporation apply at a later date for a supplemental type certificate to modify any other model included on Type Certificate No. A9NM to incorporate the same or similar novel or unusual design feature, these special conditions would apply to that model as well. Conclusion This action affects only a certain novel or unusual design feature on one airplane model. It is not a rule of general applicability and affects only the applicant who applied to the FAA for approval of this feature 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 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. List of Subjects in 14 CFR Part 25 Aircraft, Aviation safety, Reporting and recordkeeping requirements. [[Page 11321]] The authority citation for these 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 Cessna, Model 650, Citation VII airplanes modified by Universal Avionics Systems Corporation. Installed Rechargeable Lithium Batteries and Battery Systems. These special conditions require that (1) all characteristics of the rechargeable lithium batteries and battery installation that could affect safe operation of the Cessna, Model 650, Citation VII 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. In lieu of the requirements of Title 14, Code of Federal Regulations (14 CFR) 25.1353(b)(1) through (b)(4) at amendment 25-123, all rechargeable lithium batteries and battery systems on Cessna, Model 650, Citation VII airplanes, modified by Universal Avionics Systems Corporation, 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 battery installation must preclude explosion in the event of those failures. 2. Design of the rechargeable lithium batteries must preclude the occurrence of self-sustaining, uncontrolled increases in temperature or pressure. 3. No explosive or toxic gases emitted by any rechargeable 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 rechargeable lithium batteries must meet the requirements of Sec. 25.863(a) through (d). 5. No corrosive fluids or gases that may escape from any rechargeable 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 Sec. 25.1309(b) and applicable regulatory guidance. 6. Each rechargeable 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. Rechargeable lithium battery installations must have a system to control the charging rate of the battery automatically, so as 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 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 battery installation, the function of which 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 Sec. 25.1529 must contain maintenance requirements to assure that the battery is sufficiently charged at appropriate intervals specified by the battery manufacturer and the equipment manufacturer that contain the rechargeable lithium battery or rechargeable lithium battery system. This is required to ensure that lithium rechargeable batteries and lithium rechargeable battery systems will not degrade below specified ampere-hour levels sufficient to power the airplane systems 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 battery and rechargeable lithium battery systems, which could result in short-circuit or other unintentional impact damage caused by dropping or other destructive means that 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 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) in the certification basis of Cessna, Model 650, Citation VII airplanes. These special conditions apply only to rechargeable lithium batteries, lithium battery systems, and their installations. The requirements of Sec. 25.1353(b) remain in effect for batteries and battery installations on Cessna, Model 650, Citation VII airplanes that do not use lithium batteries. Issued in Renton, Washington, on February 23, 2015. Michael Kaszycki, Acting Manager, Transport Airplane Directorate, Aircraft Certification Service.
