Background 
On December 16, 2019, Airbus 
Defense and Space, Inc. applied for a 
supplemental type certificate for the installation of rechargeable lithium batteries as part of an emergency lighting installation in the Airbus Model C212–CC/–CD/–CE/–CF/–DF/–DE airplanes. The Airbus Model C212–CC/ –CD/–CE/–CF/–DF/–DE airplanes are twin-engine, transport category aircraft, with capacity for 28 passengers, and a maximum takeoff weight of 16,976 pounds. 
Type Certification Basis 
Under the provisions of title 14, Code 
of Federal Regulations (14 CFR) 21.101, 
Airbus Defense and Space, Inc. must show that the Airbus Model C212–CC/ –CD/–CE/–CF/–DF/–DE airplanes, as changed, continue to meet the applicable provisions of the regulations listed in Type Certificate No. A43EU or the applicable regulations in effect on the date of application for the change, except for earlier amendments as agreed upon by the FAA. 
If the Administrator finds that the 
applicable airworthiness regulations (e.g., 14 CFR part 25) do not contain 
adequate or appropriate safety standards for the Airbus Model C212–CC/–CD/– CE/–CF/–DF/–DE airplanes 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 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, these special conditions would also apply to the other model under § 21.101. 
In addition to the applicable 
airworthiness regulations and special conditions, the Airbus Model C212–CC/ –CD/–CE/–CF/–DF/–DE 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 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 Airbus Model C212–CC/–CD/– 
CE/–CF/–DF/–DE airplanes will 
incorporate the following novel or unusual design feature: 
An emergency lighting installation 
that contains rechargeable lithium batteries. 
Discussion 
Rechargeable lithium batteries are 
considered to be a novel or unusual 
design feature in transport category airplanes, with respect to the requirements in § 25.1353. 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 
VerDate Sep<11>2014 16:07 Nov 16, 2021 Jkt 256001 PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 E:\FR\FM\17NOR1.SGM 17NOR1khammond on DSKJM1Z7X2PROD with RULES64065 Federal Register / Vol. 86, No. 219 / Wednesday, November 17, 2021 / Rules and Regulations 
category airplanes. 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, such as provisions for thermal management. 
Special Condition 1 requires that each 
individual cell within a rechargeable lithium battery be designed to maintain safe temperatures and pressures. Special Condition 2 addresses these same issues but for the entire battery. Special Condition 2 requires the battery be designed to prevent propagation of a thermal event, such as self-sustained, uncontrolled increases in temperature or pressure from one cell to adjacent cells. 
Special Conditions 1 and 2 are 
intended to ensure that the cells and battery 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 designer. Therefore, other special conditions are intended to protect the airplane and its occupants if failure occurs. 
Special Conditions 3, 7, and 8 are self- 
explanatory. 
Special Condition 4 clarifies that the 
flammable fluid fire-protection requirements of § 25.863 apply to rechargeable lithium battery installations. Section 25.863 is applicable to areas of the airplane that could be exposed to flammable fluid leakage from airplane systems. Rechargeable lithium batteries contain electrolyte that is a flammable fluid. 
Special Condition 5 requires each 
rechargeable lithium battery installation to 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. Special Condition 6 requires each rechargeable lithium battery installation to have provisions to prevent any hazardous effect on airplane structure or systems caused by the maximum amount of heat it can generate due to any failure of it or its individual cells. The means of meeting special conditions 5 and 6 may be the same, but they are independent requirements addressing different hazards. Special Condition 5 addresses corrosive fluids and gases, whereas Special Condition 6 addresses heat. Special Condition 9 requires 
rechargeable lithium batteries to have ‘‘automatic’’ means due to the fast acting nature of lithium battery chemical reactions. Manual intervention would not be timely or effective in mitigating the hazards associated with these batteries. 
These conditions apply to all 
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. These regulations will remain in effect for other battery installations on these airplanes. 
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 Airbus 
Model C212–CC/–CD/–CE/–CF/–DF/– DE airplanes. Should Airbus Defense and Space, Inc. apply at a later date for a supplemental type certificate to modify any other model included on Type Certificate No. A43EU to incorporate the same 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 the 
Airbus Model C212–CC/–CD/–CE/–CF/– DF/–DE 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 airplanes.

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 Defense and Space S.A. Model C212–CC/–CD/– CE/–CF/–DF/–DE, as modified by Airbus Defense and Space, Inc. In lieu of § 25.1353(b)(1) through (4) 
at amendment 25–123, or § 25.1353(c)(1) through (4) at earlier amendments, each rechargeable lithium battery installation must: 
1. Be designed to maintain safe cell 
temperatures and pressures under all foreseeable operating conditions to prevent fire and explosion. 
2. Be designed to prevent the 
occurrence of self-sustaining, uncontrollable increases in temperature or pressure, and automatically control the charge rate of each cell to protect against adverse operating conditions, such as cell imbalance, back charging, overcharging, and overheating. 
3. Not emit explosive or toxic gases, 
either in normal operation or as a result of its failure that may accumulate in hazardous quantities within the airplane. 
4. Meet the requirements of § 25.863. 
5. 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. 
6. Have provisions to prevent any 
hazardous effect on airplane structure or systems caused by the maximum amount of heat it can generate due to any failure of it or its individual cells. 
7. Have a failure sensing and warning 
system to alert the flight crew if its failure affects safe operation of the airplane. 
8. If its function is required for safe 
operation of the airplane, have a monitoring and warning feature that alerts the flight crew when its charge state falls below acceptable levels. 
9. Have a means to automatically 
disconnect from its charging source in the event of an over-temperature condition, cell failure or battery failure. 
Note: A battery system consists of the 
battery, battery charger and any protective, 
monitoring and alerting circuitry or hardware inside or outside of the battery. It also includes vents (where necessary) and packaging. For the purpose of these special conditions, a battery and battery system are referred to as a battery.
