초록

항공용 내장재의 자소성 시험결과를 감항성 입증에 활용하려면 장착구역과 구성품 특성에 적합한 시험방법, 시편의 대표성, 시험조건 및 결과판정이 적용 감항기준과 동등한지를 확인해야 한다. 이를 위해 시험방법의 선정근거, 실제 장착품에 대한 시편의 대표성 및 세부 시험조건을 종합적으로 검토하는 절차가 요구된다. 본 연구는 여러 기준과 지침에 분산된 장착부위·구역별 시험방법과 세부조건을 통합 분석하여 시험 적용성, 시험대상물과 시편의 대표성, 시험조건 및 결과판정의 네 영역으로 구성된 최소입증자료 체크리스트를 제안하였다. 국내 감항인증 사례에 적용한 결과, 시험성적서에서 누락되기 쉬운 시편정보, 시험조건 및 결과 산출근거를 식별하고 체크리스트의 판단항목을 보완하였다. 전문가 검토를 거쳐 완성한 체크리스트는 개발업체와 시험기관이 감항인증에 필요한 자료를 준비하고, 감항성 심사에서 시험동등성을 일관되게 검토할 수 있는 실무기준을 제공한다.

Abstract

The use of self-extinguishing test results for airworthiness substantiation requires verification that the selected method, representativeness of the specimens, test conditions, and determination of the results are equivalent to the applicable requirements. This assessment requires a comprehensive review of the basis for selecting the test-methods , how representative the specimens are to the installed article, and detailed test conditions. This study integrated installation- and compartment-specific test requirements set out in relevant standards and guidance. Based on the findings, a minimum evidence checklist was developed covering test applicability, representativeness of test articles and specimens, test conditions, and results and determination. Application to domestic certification cases identified evidence frequently omitted from test reports and supported refinement of the checklist. Expert review further refined the checklist as a practical reference for test planning, evidence preparation, and equivalency assessment.
