P/N: 1159GSE50575-255 FUEL QUANTITY TEST BOX Qty 1/ea

NASA's Shared Services Center has issued a Special Notice for the procurement of one unit of part number 1159GSE50575-255, a Fuel Quantity Test Box required for aircraft maintenance operations. This is a sole source procurement, meaning the government has determined that only one contractor can fulfill this requirement. The procuring agency is the National Aeronautics and Space Administration Shared Services Center, acting on behalf of NASA Armstrong Flight Research Center located in Edwards, California. The part falls under NAICS Code 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and PSC Code 1680 (Miscellaneous Aircraft Accessories And Components). The notice was posted on March 10, 2026, and represents a commercial item acquisition under FAR Parts 12 and 13.

The fuel quantity test box is required to verify that the Gulfstream V aircraft's fuel systems are functioning correctly in accordance with maintenance manuals, with delivery required within 15 days of contract award to NASA Armstrong Flight Research Center's warehouse in Building 4876. The government currently intends to award the sole source contract to Alberth Aviation, Ltd., located in Magnolia, Texas, under the authority of FAR 13.106-1(b)(1)(i), based on a determination that this firm is the sole provider of the specific part. Interested organizations may challenge the sole source determination by submitting written capabilities and qualifications statements by March 12, 2026, at 7 a.m. Central Standard Time; however, oral communications are not acceptable and will not be considered. The evaluation of any capability statements will determine only whether the government should conduct a competitive procurement instead, with the final decision remaining solely within the government's discretion. Inquiries should be directed to Shanna Patterson, Procurement Specialist, at Shanna.l.Patterson@nasa.gov, and NASA Clause 1852.215-84 (Ombudsman) applies to this acquisition.
