1.0 Overview

This Statement of Work (SOW) is issued by the Federal Aviation Administration (FAA), Radar Product Division, AJW-L900, for the design, development, fabrication, testing and delivery of a replacement Air Route Surveillance Radar (ARSR4) Power Amplifier Module Test Station (PAMTS) with similar features as outlined in Exhibit 6.1 that has the ability to test and repair the ARSR4 Power Amplifier Module (PAM) Boards in according to the specifications listed below in Exhibit 6.2. This new PAMTS will replace the legacy system due to high demand of the PAMs boards, obsolescence, and repair capability issues with the current PAMTS. The new PAMTS is required to have similar mechanical design requirements and equivalent electrical performance or better using current generation components compared to the legacy system.

MIL-HDBK-217F-CHG 2 Reliability Prediction of Electronic Equipment MIL-STD-721C Definition of Terms for Reliability and Maintainability

The current legacy PAMTS consists of a PAM test console, computer/controller, PAM test fixture, self-test adapter, and various cables. It is a computer operated diagnostic test tool designed to perform functional testing, failure diagnostic, and repair verification of the ARSR4 lookdown Drivers Line Replacement Unit (LRU), Preamplifier LRU, and the Power Amplifier Modules LRUs. The PAMTS also provides instructions to the operator for the Unit Under Test (UUT) tuning and phasing. This tester includes both manual and automation test requirements.

The PAM test console is a multipurpose test console that is a two-bay cabinet containing custom equipment and commercial off-the-shelf (COTS) test equipment, which is controlled by a computer/controller. The computer/controller, monitor, and printer, for the printing of test results and test data sheets, are located on a mobile computer table.

The PAM test console and applicable cables provide output loads, test points, signal conditioning and mechanical support for the lookdown driver and preamplifier UUTs.

The PAM test fixture and applicable cables provide mechanical support for the PAM UUT and connect the PAM UUT to the PAM test console, which then provides output loads, test points, and signal conditioning for PAM UUT. The PAM test fixture also provides cooling for the PAM UUT.

This SOW’s primary focus is on a replacement PAMTS and support for the two PAM boards with future consideration for testing and support of the ARSR4 Lookdown Drivers LRU and the Preamplifier LRU.

Note:

Exhibit 6.2 refers to frequency of operation from 1215 MHz to 1400 Mhz. Unless otherwise specified, the unit shall be capable of operation within specified limits over the frequency range of 1215 MHz to 1372 MHz. Measurement of 1400 MHz shall not be made. The new limit of the FAA’s operating frequency is 1372 MHz, therefore 1400 MHz is not a requirement.

1.1 Contracting Officer’s Representative (COR)

The Contractor Officer’s Representative (COR) is formally designated with this responsibility by the Contracting Officer to provide direction and Government oversight to the Contractor on matters related to this contract.

2.0 Scope

The contractor shall furnish all labor, plant facilities, parts, supplies, materials, fixtures, equipment, tools, test equipment, technical data/expertise, and other facilities necessary to accomplish the design/redesign of a replacement PAMTS and PAM Boards test process and fixture in accordance with FAA’s manufacturing and test specifications, FAA Specifications (listed in Exhibit 6.1 and 6.2) and all other terms, conditions and provisions contained herein.

This SOW will cover all engineering costs, design costs, and the labor and material necessary to furnish a test PAMTS unit and test process to specification for the two PAM boards and fixture hardware. It is anticipated that a Firm Fixed Price Contract will be utilized for award for this effort.

3.0 QUALITY CONTROL

The contractor shall establish and maintain a Quality Control Program in accordance with the requirements of ISO-9001:2008. A compliant Quality Management System is required. An auditable system containing all elements of the ANSI/ASQ/ISO Q9001-2008 standard shall exist. Equipment will be inspected in accordance with conformance to Technical Specifications and Packaging Specifications as stated in the contract. The equipment will be accepted/rejected at destination by the FAA. Certificates of Conformance shall be supplied where applicable. The Contractor may find information at www.asq.com.

The Government and the contractor agree that equipment used to design the PAMTS and support of the PAM Boards are standard manufactured items and for that reason it may not be necessary to require Government inspection and examination of all work in progress at any time or place during normal working hours. However, in the event an abnormal failure rate (to be determined by a FAA Systems Engineer) is experienced, both parties agree that an in-plant quality control review shall be provided. Accordingly, the Government reserves the right to assign an in-plant Quality and Reliability Officer (QRO) to this contract if it is determined by the Contracting Officer to be in the best interest of the government.

Reliability shall be predicted in accordance with MIL-HDBK- 217F (CHG 2), using the parts count reliability prediction method found in appendix A. For component failure rate calculations, use the “Ground, Fixed” or Gf environment. Suitable part failure rates provided from a documented source for the specific parts used in the design may be substituted for those found in MIL-HDBK- 217F (CHG 2).

7.3.2 Electromagnetic Susceptibility and Interference: The unit shall be designed or shielded so that it is not susceptible to conducted or radiated emissions to interfere with other test systems or be affected by other test systems or cause human harm.

7.3.3 Operating Environment The unit shall meet all specifications during operation with an ambient temperature between +10 to +40 degrees C, a relative humidity from 5 to 90 percent noncondensing.

7.3.3.1 Unit Startup: The unit shall meet all electrical requirements in paragraph

9.1 within 90 seconds of being turned on from an unpowered condition for all ambient temperatures between +10 degrees and +40 degrees C.

7.3.4 Repair Capabilities: The PAMTS shall be designed and constructed so that it can be disassembled, tested, and repaired down to the subassembly level. Disassembly, reassembly, and testing shall not require any specialized tools, materials, or equipment other than those found in a typical electronics repair shop.

7.4 Additional Requirements:

7.4.1 Test Documentation: Test plans, test data sheets, procedures, assembly drawings, part list, and schedules to meet the requirements in this document shall be submitted to the FAA for review and comment at least two weeks prior to testing. The FAA shall approve these plans prior to testing.

7.4.2 Development and Testing:

7.4.2.1 Development The Contractor shall deliver an engineering report for a production PAMTS unit and test process and fixture hardware for the PAM boards that specify the measurements taken for the PAMTS, parts utilized, performance parameters, block diagram, and invoices for purchased parts. Invoices shall include any mechanical work for which NRE is paid.

7.4.2.2 Qualification Testing: After passing qualification testing at the Contractor, the PAMTS and other hardware and software shall be provided to the FAA for qualification testing at the FAA Enroute Shop. Qualification testing shall consist of operational testing, self-testing, testing of the PAM CCAs and tuning testing. The qualification test duration shall be at least one (1) week of continuous operation. The Contractor shall provide an engineering report detailing the results of the in-system qualification test.

7.4.2.3 Repair Instructions: The Contractor shall provide a repair instruction manual containing the disassembly, testing, repair, and reassembly instructions for the PAMTS and PAM test fixture. These instructions shall list all tools, equipment, and materials needed to disassemble the unit, test each subassembly, repair or replace each subassembly, tune each subassembly, tune the overall assembly, and test the overall assembly. A Test Data Sheet (TDS) that has space to record every Factory Acceptance Test (FAT) measurement shall be included in the repair manual.

Included in the repair instruction manual shall be a list of manufacturers and part numbers for each replaceable subassembly.

7.4.2.3.1 Repair Instruction Approval: The Contractor shall submit the repair instruction manual to the FAA for approval. If there are any changes needed to the manual, the changes shall be submitted to the FAA for approval.
