Use & Relationship

The static test reports consist of a static test plan, static test progress and static test final reports. These reports will be used by the procuring agency to evaluate the suitability of the planned static test, to assess static test progress, and to verify the actual static strength as well as to document the data collected to substantiate the contractor's strength analysis.

a. This document contains preparation instructions for data resulting from the technical requirements described in MIL-STD-1530, Aircraft Structural Integrity Program (ASIP). (Copies of this document are available online at http://quicksearch.dla.mil.)

b. This Data Item Description (DID) contains the format, content, and intended use information for the data deliverable resulting from the work task described in the solicitation.

Preparation Instructions

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

2FormatThe reports shall be in the contractor's format.

3ContentThe Static Test Reports shall contain the following:

3.1Static Test PlanFor each static test, this report shall contain schedule information as well as detailed information on the: test article configuration, test article instrumentation, load introduction and control system, environmental control system, data acquisition system, and critical load conditions. The report shall include:

aTest objectives and entrance/exit criteriaThe test objectives shall include obtaining data necessary to verify the structural analysis and demonstrating compliance with strength requirements. The entrance criteria shall include evaluation of test loading accuracy and pre-test predictions of strains and deflections at all critical locations. The exit criteria shall include test conditions and load levels that must be completed and data that must be acquired.

bProcesses for selection of the critical test conditionsProcesses for selection of the critical test conditions and the associated flight condition and critical structure for each condition selected for testing. Describe comparisons of test loads and environment with corresponding design analyses loads and environment.

1Describe the intermediate and maximum test loadsDescribe the intermediate and maximum test loads to be applied to the test article, including loading sequence. Include estimated dates for attainment of intermediate and maximum test loads.

2Describe all major component static test loadsDescribe all major component static test loads including shear, bending and torsion compared to design analyses.

3Describe the distributed and inertia loadsDescribe the distributed and inertia loads compared to the design analyses. Describe which loads are not properly represented and any unbalanced loads that must be reacted and their associated magnitudes and impacts.

4For each test condition, summarize all applicable test parametersFor each test condition, summarize all applicable test parameters such as, but not limited to, aircraft weight, load factor, speed, altitude, and the critical stress points of the structure for that particular test loading condition.

5Describe the temperature, moisture, etc., requirementDescribe the temperature, moisture, etc., requirement for each test condition and the method to achieve, control, and verify the environment.

cTest article configuration, test article instrumentation, test fixtureTest article configuration, test article instrumentation, test fixture, load introduction and control system (including test article protection and safety), environmental control system, and data acquisition system. For instrumentation, include drawings and photographs documenting the exact location and orientation for each.

dPredicted and allowable parametersPredicted and allowable parameters (stress or strain, deflection, temperature, pressure, load, etc.) for all measurements for each test condition.

3.2Static Test Progress ReportThis report shall contain details for static testing progress and include the following:

aTest article configuration changes made since the last progress reportTest article configuration changes made since the last progress report to include drawings and photographs.

bDeviations from the test plan

cEvents to date which affect the progress of the test programEvents to date which affect the progress of the test program (premature failures, inability to sustain load, delays in the planned test schedule, etc.).

dTest loading conditions completed since the last progress reportTest loading conditions completed since the last progress report and results.

eInspection results including any elastic buckling, permanent buckling, and failuresInspection results including any elastic buckling, permanent buckling, and failures with photographs for each.

fSchedule estimates for remaining test conditions

3.3Final Static Test ReportThis report shall describe each test condition and data obtained and shall include the following:

aDetails of test results and conclusionsDetails of test results and conclusions and necessary changes to production and delivered aircraft.

bLoad versus deflection plotsLoad versus deflection plots at locations throughout the test article and any location with permanent deformation.

cInstrumentation measurements compared to predictionsInstrumentation measurements compared to predictions for each location and condition.

dFinal inspection results including any elastic buckling, permanent buckling, and failuresFinal inspection results including any elastic buckling, permanent buckling, and failures with photographs for each.
