About this file
This is a Sources Sought Synopsis from the U.S. Air Force Sustainment Center (AFSC) conducting market research for C-5 Flap Asymmetry Brake overhaul services. The requirement involves overhauling Line Replaceable Units (LRUs) installed on the C-5M Galaxy aircraft, with two brakes required per aircraft. The brakes are critical safety components that prevent flap system damage by engaging when asymmetry is detected. The National Stock Number is 1680-01-525-8920, with part numbers 5903-105K or 5903-105L (CAGE Code 5H860). The purchase request number is FD20602700026. The government owns the overhaul manual but lacks test equipment data, and several brake components are source-controlled to the Original Equipment Manufacturer (OEM), Thomas Instruments Inc.
Source qualification is mandatory for all prospective vendors, as only Thomas Instruments (the OEM) is currently qualified under contract FA8525-25-C-B001. The RMC/RMSC code R1/C designation requires pre-qualification by the C-5 System Program Office (AFLCMC/WLSE) at Robins AFB, Georgia. The AFSC Contracting Office intends to compete this requirement as Full and Open Competition to qualified sources only. Interested parties must identify their capability and interest by 25 May 2026 by contacting Contracting Officer Staceylee Johnson, Contracting Buyer Alyssa Tanner, Program Manager Trent Miller, or Engineer Andrew Hyatt. The Sources Sought Synopsis is informational only and does not constitute a solicitation, commitment, or obligation by the government to award a contract.

Sources Sought Synopsis
FROM: Trent Miller/AFSC/409 SCMS GUMAB
TO: AFSC/PZAAB (FA8538)
LOCATION: Robins AFB, GA 31098-1813
Post Title: C-5 Flap Asymmetry Brake Overhaul
National Stock Number (NSN) Noun Part Number (Cage Code) 1680-01-525-8920 Flap Asymmetry Brake 5903-105K or 5903-105L (5H860)
SUBJECT:
The Government is conducting market research to identify potential sources that possess the repair data, expertise, capabilities, and experience to meet qualification requirements to overhaul the Flap Asymmetry Brake for the C-5 Secondary Flight Control System.
Purchase request number is FD20602700026.
ITEM DESCRIPTION
The Flap Asymmetry Brakes are Line Replaceable Units (LRUs) on the C-5M Galaxy.
These brakes are energized any time the flap asymmetry detects an out of sync condition in the Flap/Slat system. This prevents damage to the Flaps and Flap actuation system.
The Flap Asymmetry Brakes are required for flight operations of the C-5 and there are 2 brakes installed per aircraft.
Impediment to Competition:
The Government owns the overhaul manual, but does not own the data for the test equipment required for overhaul. There are also several components within the Flap Asymmetry Brake that are source controlled to the Original Equipment Manufacture (OEM), which is Thomas Instruments Inc. (CAGE: 5H860)
The RMC/RMSC code for the Flap Asymmetry Brake is R1/C. The critical application of this item requires pre-qualification of any prospective overhaul source by the Cognizant Government Engineering Activity, C-5 System Program Office, AFLCMC/WLSE, Robins AFB, Georgia. Pre-qualification will be necessary for sources other than those already approved.
Currently only one vendor, Thomas Instruments (5H860), is source qualified, as they are the Original Equipment Manufacturer (OEM) and currently overhaul the Flap Asymmetry Brake under contract FA8525-25-C-B001. As a result, any vendor who wishes to compete for this requirement must go through source qualification process which is attached to this SSS.
INTEREST
The U.S. Air Force Sustainment Center (AFSC) Contracting Office intends to compete this requirement as Full and Open Competition, to sources qualified. Interested parties may identify their interest and capability to respond to the requirement no later than 25 May 2026 by emailing:
• Contracting Officer, Staceylee Johnson (stacylee.johnson.1@us.af.mil)
• Contracting Buyer: Alyssa Tanner (alyssa.tanner.1@us.af.mil)
• Program Manager: Trent Miller (trent.miller.4@us.af.mil)
• Andrew Hyatt, Engineer Andrew Hyatt (andrew.hyatt.9@us.af.mil)
