The contractor shall adhere to any Federal, State, or local health and well-being regulations and guidelines for contractor-hosted in-person gatherings with Government personnel.

4.2 Systems engineering.

4.2.1 Environment, Safety, and Occupational Health (ESOH).

4.2.1.1 Hazardous materials. The TDP may contain hazardous materials reference such as finished specs and coating systems, and the contractor shall manage these hazardous materials, including those embedded in the system or used during operation or maintenance, as an element of the Systems Engineering process. The system shall not generate or use Class I or Class II Ozone Depleting Substances (ODS) during operation, maintenance, or disposal. The use of hexavalent chromium is also prohibited. The contractor shall list any hazardous materials to be delivered under this contract, including locations, quantities, and special handling and disposal procedures. This information shall be submitted in an ECP (Para 4.4.1).

4.2.2 Access Panel. The contractor shall develop an access panel to allow ease of maintenance for installing and removing the main CB2 circuit breaker. The access panel shall be designed to allow installation/removal of the circuit breaker without having to remove any other internal components. Access panel shall be secured with fasteners (screws with internal nut-plate design). Access panel proposal shall be submitted in an ECP and accepted by the program office prior to initial production readiness and testing.

4.3 Testing and evaluation.

4.3.1 Initial production test procedures. The contractor shall develop detailed test procedures for the initial production test at the contractor facility, which shall address all requirements identified in the drawing package and this SOW. The test procedures shall include but not limited to data record sheets, supporting charts or graphs, and identification of test instruments by manufacturer, model number, and serial number. IAW DD1423 ELIN A001 (DI-NDTI-80603A, Test Procedure)

4.3.2 Initial production testing. Initial production testing of five (5) production MHU A1 Power Control Units shall be completed in three (3) phases to ensure adequate and efficient production-representative articles for Initial Operational Test and Evaluation (IOT&E). This phase approach will also assist with the initial production base-line and increase the production rate to lead to Full-Rate Production (FRP) upon successful completion of IOT&E. The first phase of Developmental testing of five (5) initial production MHU A1 Power Control Units shall be completed at the contractor’s facility and witnessed by one or more Government representative(s). Upon successful completion, the contractor shall ship the quantity of five (5) initial production MHU A1 Power Control Units to Robins AFB for the second phase of initial production testing: Qualification Testing using a MHU Interface Test Adapter (ITA) within the 569th EXMG organization. If all five (5) initial production units successfully pass Qualification Testing, two (2) of the five (5) initial production units will be shipped by AFLCMC/ROZ to a continental United States (CONUS) location (to be determined) to be installed on two (2) MHU-196 trailers for the third phase of initial production testing: IOT&E. Each initial production unit shall be operationally tested for a minimum of 10 hours on each MHU-196 trailer. If both trailers with newly manufactured MHU A1 Power control units installed successfully pass IOT&E without failure, the Government shall approve the manufacture and shipment of additional units. The contractor shall be responsible for all shipping costs of the five (5) initial production MHU A1 Power Control Units to Robins AFB.

4.3.3 Initial production test report. The contractor shall submit a first production test report upon completion of the first production test at the contractor facility. The test report shall document all testing performed, including results of any unsuccessful test attempts. IAW DD1423 ELIN A002 (DI-NDTI-80809B, Test/Inspection Report)

The contractor shall be responsible for any rework necessary to meet the requirement and restore the initial production MHU A1 Power Control Units to a serviceable, "like new" condition while retaining configuration integrity. The contractor shall be responsible for all costs associated with shipping any failed initial production MHU A1 Power Control Units from Robins AFB and/or field location to the contractor's facility for rework and return shipping of all reworked initial production MHU A1 Power Control Units from the contractor’s facility back to Robins AFB for additional follow-up initial production testing.

4.4 Configuration management.

4.4.1 Engineering Change Proposals (ECPs). Notwithstanding any other provision in the contract, no contractor or subcontractor's change in design, fabrication, assembly, part, material, process, or source of supply shall be made to the TDP unless such change is submitted in writing by ECP and approved by the procuring activity. Any request for change shall be accompanied by complete documentation supporting the need for the change. A system safety impact statement shall be provided as part of the submittal; it shall quantify and qualify the system safety risk identified. A Notice of Revision (NOR) shall be submitted with each ECP. Should the Government approve an ECP, the contractor shall be responsible for submitting changes to the TOs to reflect the changes made in the ECP.

4.4.1.1 Technical Data Package (TDP). The TDP (also known as the drawing package) forms a part of this SOW and constitutes the end item product drawings. The TDP is mandatory for use in design and building the MHU A1 Power Control Unit and no deviation from the drawings is permissible without prior approval of the procuring activity. Where tolerances could cumulatively result in incorrect fits, the contractor shall provide tolerances within those prescribed on the drawings to ensure correct fit, assembly, and operation of the MHU A1 Power Control Unit. If during the manufacturing process of initial production MHU A1 Power Control Units discrepancies are noted with the TDP, the contractor shall notify the procuring activity of such discrepancies. Any data prepared by the contractor or obtained from a vendor to support fabrication and manufacture of the MHU A1 Power Control Unit shall be made available, upon request, for inspection by the procuring activity.
