Use & Relationship

The Engine Control System Component Test Report Requirements describe the format and content of deliverable information from the environmental qualification testing of engine control system components. It provides clear and complete instructions for the preparation of qualification substantiation data products to be submitted for approval by the airworthiness authority, resulting from applicable tasks delineated in the solicitation.

a. This Data Item Description (DID) contains the format, content, and intended use information for the data deliverable resulting from the work task described in 5.10.4.1 of MIL-STD-3087.

b. This DID supersedes DI-NDTI-81897.

10.1System Description.
10.2Unit Construction and Assembly.
10.3Component Non-Conformances.Any non-conformances shall be described here, with reference to 17. Appendix A for the actual detailed documentation of such, including any corrective action taken. The report shall explain the rationale for testing a nonconforming part or reworked part. Airworthiness Authority approval of the non-conformances shall be included in Appendix A.
11Test Plan.
11.1Test Plan SummarySummarize the test plan in a table, including the order of testing, the name of the test, the test procedure, and the test plan paragraph number.
11.2Plan ApprovalSpecify when/how the Airworthiness Authority approval of the test plan was provided and include in 18. Appendix B the documentation of such.
11.3Deviation to the Test Plan (Global)Explain any global deviations to the test plan that had to be made and reference Appendix B for the documentation of the deviations, along with Airworthiness Authority approval.
12Test Readiness Review (TRR).Indicate if a TRR was held. Provide information on whom, when and where, and the outcome of the TRR.
12.1Include documentation of Airworthiness Authority approval to test.
12.2Include TRR materials in 19. Appendix C.
13Test Summary.Include a table similar to the one illustrated below. Acronyms in the table above are defined as follows: ATP - Acceptance Test Procedure; N/A - Not applicable; S/N - Serial Number; UUT - Unit Under Test.
14Individual Test Summaries.For each of the tests listed in the table of item 13, provide in separate test subparagraphs, each beginning at the top of a new page, the following information. These summaries are typically 2 to 4 pages in length each, but may be exceeded as necessary to adequately cover the required information.
14.1Significant events that occurred or relevant observations.
14.2Test procedure errors made or deviations taken.
14.3The effect, if any, of (a) and (b) on the test outcome or results.
14.4Pass/Fail criteria that were not met and the significance of the failure.
14.5Proposed remedies or design changes as a result of failures.
14.6Any other relevant information.
14.7Statement on whether or not the Unit Under Test (UUT) met its qualification test objectives.
15Disassembly and Inspection.
15.1Each disassembled part or subcomponent shall be discussed in detail as to: condition with respect to a new part, continued usability, and likelihood of impending failure.
15.2Photos of each part or subcomponent must be clear and in color; photocopied pictures are not acceptable if they do not provide adequate detail.
16Conclusion.
17Appendix A - Component Non-Conformance.
17.1Include all material discrepancy actions, plus any other documentation of unit nonconformance.
17.2Documentation of Airworthiness Authority approval.
18Appendix B - Test Plan Documentation.
18.1Documentation of Airworthiness Authority approval.
18.2Documentation of Contractor approval.
19Appendix C - Test Readiness Documentation.
19.1Documentation of Airworthiness Authority approval.
19.2TRR presentation or other material.
20Appendix D - ATPs or Calibrations Conducted During Testing.
21Appendix E - Individual Test Reports and Results.Individual reports shall be included in separate 'tabbed' sections. Note that these reports shall not duplicate any of the information provided up through item 20, unless absolutely necessary.
21.1The report shall be organized to generally follow the approved test procedure.
21.2Photographs of all test equipment and test setups shall be included.
21.3Environmental test conditions shall be documented.
21.4Detail the conduct of the test, including a chronological history of events and incidents connected with the test.
21.5A complete analysis of results shall be included, and any pertinent performance/calibration data for illustration purposes.
21.6Clearly highlight (as illustrated in the table below, including reference to applicable data sheets) and discuss in detail any test anomalies, and propose any remedies, if necessary.
21.7Tables and charts shall be utilized to clearly present and summarize the test data.Data for an entire test, presented in the example tabular format below, has been deemed acceptable in most cases.
21.8Component condition at test completion shall be detailed or discussed, and conclusions and recommendations rendered.
21.9State in the test report whether component performance and function are within established limits.State in the report whether the component under test exhibited any fluid leakage and if fluid leakage is of a nature and rate specified in the engine or component specification. Hang-ups or hesitations of any component, if any, shall be described in the report.
21.10State in the report if recalibrations indicate that no component has changed its calibration beyond allowable service limits.
