Background On January 18, 2016, Avmax Aviation Services, Inc., (Avmax) applied for a supplemental type certificate
(STC)to install a rechargeable lithium battery on the Viking Air, Ltd. (Viking Air), models DHC-6-100/-200/-300, Twin Otter, Turbopropeller airplanes. These are normal category airplanes, powered by two Pratt & Whitney Canada PT6A-20 engines (-100 and -200) or two PT6A-27 engines (-300). The maximum takeoff weight is 12,500 pounds (5,670 kg) for the -300, but lesser for the -100 and -200. The current regulatory requirements for part 23 airplanes do not contain adequate requirements for use of rechargeable lithium batteries in airborne applications. This type of battery possesses certain failure and operational characteristics with maintenance requirements that differ significantly from that of the nickel-cadmium (Ni-Cd) and lead-acid rechargeable batteries currently approved in other normal, utility, acrobatic, and commuter category airplanes. Therefore, the FAA is proposing this special condition to address
(1)all characteristics of the rechargeable lithium batteries and their installation that could affect safe operation of the modified models DHC-6-100/-200/-300 Turbopropeller airplanes, and
(2)appropriate Instructions for Continued Airworthiness
(ICA)that include maintenance requirements to ensure the availability of electrical power from the batteries when needed. Type Certification Basis Under the provisions of § 21.101, Avmax must show that the models DHC-6-100/-200/-300 Turbopropeller airplanes, as changed, continue to meet the applicable provisions of the regulations incorporated by reference in Type Certificate Data Sheet No. A9EA 4 or the applicable regulations in effect on the date of application for the change. 4 *http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgMakeModel.nsf/0/AB4F5DD989BB1B4E86257FF100542804?OpenDocument.* If the Administrator finds that the applicable airworthiness regulations ( *i.e.,* Civil Air Regulations [CAR] 3) do not contain adequate or appropriate safety standards for the models DHC-6-100/-200/-300 Turbopropeller airplanes because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 21.16. The FAA issues special conditions, as defined in § 11.19, under § 11.38 and they become part of the type certification basis under § 21.101. Special conditions are initially applicable to the models for which they are issued. Should the applicant apply for an STC to modify any other model included on the same type certificate to incorporate the same novel or unusual design feature, these special conditions would also apply to the other model under § 21.101. Novel or Unusual Design Features The Viking Air models DHC-6-100/-200/-300 Turbopropeller airplanes will incorporate the following novel or unusual design features: The installation of a rechargeable lithium battery as a main or engine start aircraft battery. Discussion The applicable regulations governing the installation of batteries in general aviation airplanes were derived from CAR 3 as part of the recodification that established 14 CFR part 23. The battery requirements identified in § 23.1353 were a rewording of the CAR requirements. Additional rulemaking activities, as a result of increased incidents of Ni-Cd battery fire or failures, incorporated § 23.1353(f) and
(g)at amendments 23-20 and 23-21 respectively. However, the regulation prescribed was not for lithium battery installations. The proposed use of rechargeable lithium batteries prompted the FAA to review the adequacy of these existing regulations. We found that the existing regulations do not adequately address the safety of lithium battery installations. Current experience with rechargeable lithium batteries in commercial or general aviation is limited. However, other users of this technology, ranging from personal computers, to wireless telephone manufacturers, to the electric vehicle industry, have noted safety problems with rechargeable lithium batteries. These problems include overcharging, over-discharging, flammability of cell components, cell internal defects, and those resulting from exposure to extreme temperatures that are described in the following paragraphs. 1. *Overcharging:* In general, rechargeable lithium batteries are significantly more susceptible than their Ni-Cd or lead-acid counterparts to thermal runway, which is an internal failure that can result in self-sustaining increases in temperature and pressure. 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 rechargeable lithium battery cells beyond the manufacturer's recommended specification 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 Ni-Cd batteries. In addition, over-discharging has the potential to lead to an unsafe condition (creation of dendrites that could result in internal short circuit during the recharging cycle). 3. *Flammability of Cell Components:* Unlike Ni-Cd and lead-acid batteries, some types of rechargeable 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. 4. *Cell Internal Defects:* The rechargeable lithium batteries and rechargeable battery systems have a history of undetected cell internal defects. These defects may or may not be detected during normal operational evaluation, test and validation. This may lead to an unsafe condition during in service operation. 5. *Extreme Temperatures:* Exposure to an extreme temperature environment has the potential to create major hazards. Care must be taken to ensure that the lithium battery remains within the manufacturer's recommended specification. Applicability The special conditions are applicable to the models DHC-6-100/-200/-300 Turbopropeller airplanes. Should Avmax apply at a later date for an STC to modify any other model included on the same type certificate 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 the models DHC-6-100/-200/-300 Turbopropeller 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 subject contained herein. Therefore, notice and opportunity for prior public comment hereon are unnecessary and the FAA finds good cause, in accordance with 5 U.S.C. 553(b)(3)(B) and 553(d)(3), making these special conditions effective 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.

(1)Safe cell temperatures and pressures must be maintained during— i. Normal operations; ii. Any probable failure conditions of charging or discharging or battery monitoring system; and iii. Any failure of the charging or battery monitoring system not shown to be extremely remote.
(2)The rechargeable lithium battery installation must be designed to preclude explosion or fire in the event of 1(1)(ii) and 1(1)(iii) failures.
(3)Design of the rechargeable lithium batteries must preclude the occurrence of self-sustaining, uncontrolled increases in temperature or pressure.
(4)No explosive or toxic gasses 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.
(5)Installations of rechargeable lithium batteries must meet the requirements of § 23.863(a) through
(d)at amendment 23-34.
(6)No corrosive fluids or gases that may escape from any rechargeable lithium battery may damage surrounding structure or any adjacent systems, equipment, electrical wiring, or the airplane in such a way as to cause a major or more severe failure condition, in accordance with § 23.1309 at amendment 23-49 and applicable regulatory guidance.
(7)Each rechargeable lithium battery installation must have provisions to prevent any hazardous effect on structure or essential systems that may be caused by the maximum amount of heat the battery can generate during a short circuit of the battery or of its individual cells.
(8)Rechargeable lithium battery installations must have— i. A system to automatically control the charging rate of the battery to prevent battery overheating and overcharging; and either ii. 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 iii. 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.
(9)Any rechargeable lithium battery installation, the function of which is required for safe operation of the aircraft, 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 (see note 1) of the aircraft. Note 1: Reference § 23.1353(h) for dispatch consideration.
(10)The Instructions for Continued Airworthiness
(ICA)required by § 23.1529 must contain maintenance requirements (see note 2) to assure that the battery has been sufficiently charged (see note 3) at appropriate intervals specified by the battery manufacturer and the equipment manufacturer that contain the rechargeable lithium battery or rechargeable lithium battery system. The lithium rechargeable batteries and lithium rechargeable battery systems must not degrade below specified ampere-hour levels sufficient to power the aircraft system. The ICA must also contain procedures for the maintenance of replacement batteries (see note 4) to prevent the installation of batteries that have 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. Note 2: Maintenance requirements include procedures that—
(a)Check battery capacity, charge degradation at manufacturers recommended inspection intervals.
(b)Replace batteries at manufacturers recommended replacement schedule/time to prevent age related degradation. Note 3: The term “sufficiently charged” means that the battery must retain enough charge, expressed in ampere-hours, to ensure that the battery cells will not be damaged. A battery cell may be damaged by low charge ( *i.e.,* below certain level), resulting in 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 4: Replacement battery in spares storage may be subject to prolonged storage at a low state of charge. Issued in Kansas City, Missouri on April 18, 2017.
