Excerpt: ... 7 / 30 / 07 AC 20-158 ( a ) The purpose and scope of the similarity assessment; ( b ) Specific systems addressed by the similarity assessment; ( c ) Data that will be used from the previously certified systems, equipment, and aircraft; and ( d ) Any significant differences between the aircraft and system installation proposed for certification and the aircraft and system installation from which the data will be used. Include appropriate margins to account for similarity uncertainty. c. Compliance Reports. One or more compliance reports may be necessary to document the results of your test, analysis, or similarity assessments. For new or significantly modified aircraft, HIRF compliance reports may include many system and equipment test reports, aircraft test reports, and HIRF vulnerability analysis reports. For these types of HIRF certification programs, a compliance summary report may be useful to summarize the results of tests and analysis. For HIRF certification programs on relatively simple systems, a single compliance report may be adequate. ( 1 ) Test Reports. Comprehensive test reports should be produced at the conclusion of HIRF compliance testing. The test reports should include descriptions of the salient aspects of equipment or system performance during the test, details of any area of noncompliance with HIRF requirements, actions taken to correct the noncompliance, and any similarity declarations. You should also provide supporting rationale for any deviations from system performance observed during testing. ( 2 ) Analysis Reports. Analysis reports should describe the details of the analytical model, the methods used to perform the analysis, and the results of the analysis. The reports should identify any modeling uncertainty and justify th...
