About this opportunity
The U.S. Air Force Sustainment Center is conducting market research to identify sources qualified to overhaul C-5 Flap Asymmetry Brakes (NSN 1680-01-525-8920, part numbers 5903-105K or 5903-105L) for the C-5M Galaxy, with responses due by May 25, 2026. This is full and open competition, but only to sources that complete mandatory pre-qualification by the C-5 System Program Office (AFLCMC/WLSE) at Robins Air Force Base, Georgia.
Flap Asymmetry Brakes are Line Replaceable Units critical to flight operations; two brakes are installed per aircraft and prevent system damage by engaging when flap asymmetry is detected. The government owns the overhaul manual but does not own test equipment data, and several brake components are source-controlled to Original Equipment Manufacturer Thomas Instruments Inc. (CAGE 5H860). Thomas Instruments is currently the sole qualified source, performing overhaul under contract FA8525-25-C-B001.
Prospective vendors must meet extensive pre-qualification criteria: ISO 9001-certified quality management, detailed facility and equipment inventories, demonstrated prior experience repairing critical aircraft parts on large transport aircraft with supporting documentation, compliance with USAF overhaul manual 16C1-4-18-3, full material and heat treatment traceability, performance of a minimum 80 percent of repair work in-house, and first article testing unless the bidder has repaired or manufactured this item within the last five years. Work is performed at Robins Air Force Base, Georgia. Interested parties should contact Contracting Officer Staceylee Johnson, Contracting Buyer Alyssa Tanner, Program Manager Trent Miller, or Engineer Andrew Hyatt.

C-5 Flap Asymmetry Brake Overhaul
NSN: 1680-01-525-8920
Part No. 5903-105K or 5903-105L
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.
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)
QUALIFICATION REQUIREMENTS
Source Qualification Statement and minimum requirements necessary to become a qualified bidder are attached to this Sources Sought Synopsis.
