SUBJECT: Single Source Justification for Pin Wire Tester Eval and Repair 1. Background: The 555 SWES has a requirement for a comprehensive Test, Teardown, and Evaluation (TT&E) on an inoperable Radio Frequency (RF) M880 amplifier within the Tinker Pin Tester (PT) system to determine its repairability. This amplifier is a critical asset directly required to test the electromagnetic pulse (EMP/EMF) nuclear hardness resistance of Line-Replaceable Units (LRUs) for the B-2 aircraft. The unit became inoperable at the end of 2023 following an audible "popping" event, and previous diagnostic attempts have failed to identify the root cause of the failure. The estimated cost is $75,000.

2. Justification: Fischer Custom Communications, Inc. is the sole identified source possessing the proprietary technical drawings, test fixtures, and domain engineering expertise required to interface with and refurbish this custom hardware without risking catastrophic damage to the B-2 test apparatus. Fischer was contacted and does not have any vendors that can perform the needed evaluation and subsequent repair.
3. Statement: The proposed sole source contractor is the only contractor that can satisfy the Government’s requirements.
Fischer Custom Communications, Inc
19220 Normandie Ave Unit B
Torrance CA 90502-1011
POC David Fischer 310-310-3300
Cage Code 53779
Small Business

4. Market Research: Market research was performed to determine whether alternative commercial or noncommercial vendors could evaluate and repair the custom M880 amplifier. Inquiries and database reviews (SAM.gov, technical order reviews) confirmed that the original equipment manufacturer (OEM), Maxwell, is defunct. Fischer Custom Communications, Inc. is the sole identified source possessing the proprietary technical drawings, test fixtures, and domain engineering expertise required to interface with and refurbish this custom hardware.
5. Avoiding Future Single Source: The Government will continue to monitor the market to see if competition exists if the requirement shall occur in the future.
6. Contracting Officer Determination: I have determined, in accordance with RFO 12, that the circumstances of this contract action deem only a single source is reasonably available. signed by
