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
