STATEMENT OF WORK

Procurement of ASR-9 Module A Power Supply Repair Kit P/N 852000

1. BACKGROUND

Radar Technical Program Support Group, AJW-L910, currently provides logistics support to 135 ASR-9 field radar sites. The Multivoltage Power Supply (MVPS) distributes the power to the different subsystems for the Receiver and Weather Cabinets for the ASR-9. The MVPS uses grouped power supply modules for the different output requirements. A single -15/+100 V Module A (MOD A) power supply is contained in the MVPS in the Receiver Cabinet and three identical -15/+100 V MOD A power supplies are contained in the Weather/SCIP Cabinet. The MOD A provides power to the Target I-F Panel Assembly, Target Receiver Assembly, Frequency Generator Rack, and Interface Panel in the Receiver Cabinet and the Weather I-F Panel Assembly, Weather Receiver Assembly, Interface Panel, and the Dual Card Rack for the Weather Cabinet. The internal components of the MOD A are obsolete and therefore can no longer be repaired unless the components are replaced. The Federal Aviation Administration (FAA) has determined it necessary to replace the internal components with a repair kit that updates the MOD A and mitigates the obsolescence issues. The FAA has determined that the +100 V output is no longer needed to support the current ASR-9 Baseline.

This Statement of Work describes the procurement of MOD A Repair kits used to update and repair NSN 6130-01-295-6625.

2. SCOPE OF WORK

The contractor must furnish all labor, facilities, equipment, and materials to produce the ASR-9 MOD A Repair Kits for the FAA as outlined in each section that follow. The specific quantities of units include the following:

1. Four (4) First Article Module A Power Supply Repair Kits

2. Thirty-Four (34) Production Module A Power Supply Repair Kits

3. REQUIREMENTS

3.1 Design, Construction, and Testing

The contractor shall design, construct, and test the repair kits in accordance with (IAW) the following:

I. Attachment 01. SOW_ASR-9 Spec Sheet PDS 23698 II. Attachment 02. SOW_ASR-9 Spec Sheet PDS 23699 III. Attachment 03. SOW_ASR-9 Spec Sheet FAA-G-2100H IV. Attachment 04. SOW_ASR-9 Spec Sheet 850144 V. Attachment 05. SOW_ASR-9 Spec Sheet 852000 VI. Attachment 06. SOW_ASR-9 Spec Sheet D852011

Specifically, the repair kit will allow the existing MOD A Power Supplies to be updated as a Form, Fit, Function (FFF) replacement. In addition to the requirements listed in the attachments, the MOD A power supply must be capable of the following in accordance with the Legacy (OEM) design:

· +100V/0.2 dc output is not required, but the associated BIT circuit should have J101 pins 8 and 9 connected to prevent system fault

· Voltage must be adjustable when installed

· Kit must be compatible when paired with Legacy units

· Kit must be able to carry full load if paired power supply fails

3.2 First Article Unit Delivery

Contractor must deliver four (4) verification units with complete test data package, schematic and diagnostics, illustrating conformance to SCD 852000 (Attachment 5), PDS 23698 (Attachment 1), and PDS 23699 (Attachment 2) and test procedures therein. The complete Test Data Package (TDP) must include QTP (Qualification Test Procedure) and First article Acceptance Test Procedure (ATP) that complies with PDS 23698 par. 5.1.2 and 5.1.1 and 850144. Each first article unit must include a test data sheet showing the results of tests for input isolation, output isolation, panel meter monitor output voltage, loss of single phase (for 3 phase power supply), overvoltage transient response, under voltage transient response, output ripple, output regulation, remote sense, output voltage adjustment, voltage stability, load transient response, over current protection, over voltage crowbar, inrush current, cooling air temperature rise, UPS and BIT (built in test). Delivery shall occur no later than (NLT) 200 days at receipt of order (ARO).

3.3 First Article Unit Analysis

Upon receipt of first article units, FAA shall perform analysis to verify and ensure product conformance to requirements in PDS 23698 (Attachment 1) and PDS 23699 (Attachment 2). Operational performance shall be evaluated via bench testing and in-system testing in accordance with PDS 23698 (Attachment 1) and PDS 23699 (Attachment 2). System tests shall consist of installing the kit into the next higher assembly and all the applicable positions within the Multivoltage Power Supply and verifying performance. FAA will have 200 days to accept or reject first article.

3.4 Production Units

Delivery of production units shall begin NLT 180 days after First Article Acceptance has been provided to the contractor. Each production unit should include proof of conformance to the Factory Acceptance Test.

3.5 Documentation

The contractor must provide all written documentation in Microsoft Office WORD or EXCEL format, 2013 or later version. All documentation must be provided with First Article units to be eligible for approval. The contractor must provide all drawings of circuit board layouts and schematics. All PDF format documents must be searchable. At least one PDF format copy of all documents must be provided. The following documentation is to be provided by the contractor:

· Overview

· Operation

· Repair procedures

· Parts list

· Schematic drawings
