Use & Relationship

The Engine Control System Component Test Plan Requirements describe the format and content of engine control system component environmental qualification test plans. It provides clear and complete instructions for the preparation of environmental test plan 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 5.10.3 of MIL-STD-3087.

b. This DID supersedes DI-NDTI-81895.

Preparation Instructions

1Reference Documents.The applicable issue of any documents cited herein, including their approval dates and dates of any applicable amendments, notices, and revisions, shall be as specified in the contract.

2.1Title, number, and date.

2.2Contractor's Name.

2.3Contract number.

3Title Page.

3.1Title, number, and date.

3.2Contractor's Name.

3.3Name(s) of the author(s).

3.4Contract number.

4Abstract.

4.1Objective of the plan.

4.2Brief statement of the contents of the plan.

5Table of Contents.

6List of Tables.When used in a separate series, tables shall be given Roman numerals.

7List of Illustrations.

7.1Figure numbers and captions of all illustrations.

7.2Photographs, charts, and graphs shall be treated as illustrations and given figure numbers.

8Applicable Documents.

9Component Description.

9.1Functional description.

9.1.1Component operational block diagram or schematic.

9.1.2Relationship of the component to the overall control system, including interface with other subsystems (airframe or engine).

9.2Physical description.

9.2.12-D and isometric drawings.

9.2.2Photos (if available).

9.3Identification of any material discrepancies.

9.3.1List any Material Review Board items.

9.3.2Describe in detail any material discrepancies, corrective actions, and rationale for using any part that does not conform to engineering drawings.

10Component Performance Requirements.

10.1Required performance (pass/fail criteria) must be traceable to higher level specification(s).Include a table that traces the performance requirements to the next highest level specification, or higher if necessary, to justify the pass/fail values. Each parameter and its limits shall reference a specific paragraph number.

10.2If the parameter and its pass/fail limits cannot be easily translated from one specification to the next (e.g., engineering units to electrical units), then there must be an explanation of how the conversion was made.

11Testing to be Performed.

11.1List of tests with a simplified description of each, the model specification or other requirement paragraph, and any standard procedure reference.

11.2Order of testing and explanation if it deviates from the order specified.

11.3Any planned Acceptance Test Procedure(s) (ATP)/calibrations, inspections, or other disassemblies planned between the tests.

11.4For each test requirement, specify whether it will be satisfied via test, similarity or analysis.

11.5Specify how many units will be tested and for which tests.

12Test Summaries.Test summaries shall contain the following information.

12.1Test Purpose.Provide a clear, concise, easily understood description.

12.2Test Performance.Explain if the test will be performed exactly as described in the referenced standard or procedure or if it will be some modified version. If a similarity or analysis report will be prepared in lieu of testing, then a summary of the rationale shall be included here, with the remaining items c through g marked as N/A or left out completely.

12.3Any planned ATPs/calibrations, inspections, or other disassemblies planned during the test sequence.

12.4Data monitoring and recording.Explain what will be recorded and monitored and how it will be captured (i.e., continuous vs. sampling).

12.5Unit testing conditions.The environmental cycle/conditions, the unit functional cycle/conditions, and the unit operating cycle/conditions must all be defined.

12.6Pass/fail criteria.Specify/reference the performance table at the front of the document. If different, then justify. List any other criteria such as passage of post-test ATPs or detailed inspections.

12.7Test data presentation.Explain exactly what information will be provided as documentary evidence of test passage and in what form it will be presented.

Detailed Test ProcedureSeparate tabbed sections or appendices shall be provided, one for each test procedure. The test procedure shall not duplicate information already provided in Part 1 of the test plan. These procedures may be submitted individually at the discretion of the contractor. However, Part 1 of the test plan shall have already been approved prior to the contractor submitting any detailed procedures for approval. In addition to providing detailed step-by-step instructions for test execution, the procedure shall also contain the following information.

1Component mounting details and test orientation with orthogonal axis definition.

2Monitoring sensor placement locations.

3Drawing/sketches of the test setup showing all pertinent equipment by name and part number.

4Planned test location.

5Serial number of the component undergoing test.

6List of test equipment (including ranges and accuracies) and any special hardware or test equipment requirements.

13Validation/Verification of Testing from the Government.The plan shall include written validation/verification from the Government that it includes all testing required by the applicable specification.
