Each CTSO is a criterion which the concerned aeronautical materials, parts or appliances used on civil aircraft must comply with when it is presented for airworthiness certification. Single Phase 115 VAC, 400 Hz Arc Fault Circuit Breakers 1. Purpose. This China Civil Aviation Technical Standard Order (CTSO) is for manufacturers applying for single phase 115 VAC, 400 Hz arc fault circuit breakers (AFCBs) CTSO authorization (CTSOA). This CTSO prescribes the minimum performance standards(MPS) that AFCB must first meet for approval and identification with the applicable CTSO marking. 2. Applicability. This CTSO affects new application submitted after its effective date. Major design changes to article approved under this CTSO will require a new authorization in accordance with section 21.353 of CCAR-21R4. 3. Requirements New models of AFCBs identified and manufactured on or after the English Translation Version for Reference Only CAAC CTSO-C178 - 2 - effective date of this CTSO must meet the MPS in SAE Internationals Aerospace Standard (AS) 5692, Arc Fault Circuit Breaker (AFCB), Aircraft, Trip-Free Single Phase 115 Vac, 400 Hz-Constant Frequency, dated October 2004, and the additional requirements of this document a. Functionality. This TSOs standards apply to equipment intended to provide an equivalent level of thermal protection of existing thermal circuit breakers, with the additional capability to detect and react to arc fault conditions, thus diminishing damage to wiring systems by prolonged arcing, which could start a fire. b. Additional Functional Requirements. AFCBs may have separate indication of thermal and arcing faults to assist in fault isolation and performing proper repairs. c. Failure Condition Classifications. Failure of the function defined in paragraph 3.a of this CTSO is a major failure condition. Develop the system to, at least, the design assurance level equal to this failure condition classification. NOTE: A major failure condition reduces the ability of the airplane or the crew to cope with adverse operating conditions. There is a significant reduction in safety margins or functional capabilities; a significant increase in crew workload or in conditions impairing crew efficiency; discomfort to the flight crew or physical distress to passengers or cabin crew, possibly including injuries. English Translation Version for Reference Only CAAC CTSO-C178 - 3 - d. Functional Qualification. Demonstrate the required performance under the test conditions and procedures specified in SAE AS 5692, Section 4. e. Environmental Qualification. Test the equipment according to RTCA, Inc. document RTCA/DO-160E, Environmental Conditions and Test Procedures for Airborne Equipment, dated December 9, 2004, or most current revision. f. Software Qualification. If the article includes a digital computer, develop the software according to RTCA/DO-178B, Software Considerations in Airborne Systems and Equipment Certification, dated December 1, 1992. g. Electronic Hardware Qualification. If the article includes aircraft products or appliances incorporating custom micro-coded components, such as application specific integrated circuits (ASIC), programmable logic devices (PLD), field programmable gate arrays (FPGA), or similar electronic components in the design, develop the hardware using RTCA, Inc., Document RTCA/DO-254, Design Assurance Guidance for Airborne Electronic Hardware. h. Deviations. For using alternative or equivalent means of compliance to the criteria in this CTSO, the applicant must show that the equipment maintains an equivalent level of safety. Apply for a deviation under the provision of 21.368(a) in CCAR-21R4. English Translation Version for Reference Only CAAC CTSO-C178 - 4 - 4. Marking. a.
