Ultrasonic Test Sets/Metal Flaw Detector Repairs

The Government is conducting market research to identify potential sources that possess the repair data, expertise, capabilities, and experience to meet qualification requirements for the repair of Ultrasonic Test Set NSNs: 6635-01-667-6367 and 6635-01-641-9510 and the Metal Flaw Detector NSN: 6635-01-642-7420 for USAF personnel. The listed NSN’s shall be repaired to working condition in accordance with the original equiupment manufacturer’s operations manual. Our repair strategy is a two-year contract (basic plus one option year) and will continue through FY22. The projected repair quantities would be any combination of the mentioned NSN’s not to exceed 100 total repairs per option/year.

The Ultrasonic Test Sets are a type of Non-Destructive Testing (NDT) that is utilized to detect internal discontinuities ranging from cracks to disbonds by using sound. Ultrasonic test sets can be used on almost any material to locate dicontinities from large disbonds, down to the smallest defects. It can also be used to measure overall thickness of a material, and the specific depth of a defect. The part requires little or no preparation; however, knowledge of the internal geometry of a part is critical to interpretation of any defect signal. This test set is used on aircraft structures and engine components to inspect for cracking, bonding, and corrosion.

The Metal Flaw Detector is also a type of NDT, referred to as eddy current, that is utilized to detect dicontinuities in parts that are conductors of electricity. The detector generates an alternating current that is designed to go through a coil of copper wire that has been placed in a holder called a ″probe.″ This results in the coil producing an alternating magnetic field that when placed near a conductor, generates electrical currents within the conductor. When the detector encounters an obstacle such as a crack, the normal path and strength of the currents is changed and this change is detected, processed and then displayed on the instrument display. This flaw detector is used on airfract structures and engine components to inspect for cracking around and in fastener holes or engine rotating components.
