Reduced Gravity Modification of 737-73W Aircraft

The contract pertains to the sole-source modification of a Boeing 737-73W aircraft to serve as a reduced gravity test bed in support of NASA’s Artemis program, specifically for validating space suit performance under simulated microgravity conditions. The work scope includes a feasibility assessment, cabin modifications, overdue maintenance, airworthiness restoration, and exterior repainting, all required to be completed within a tight performance period from June 1, 2026, to October 1, 2026. The contract is awarded to Denmar Technical Services, Inc. under FAR 6.103-1, citing 10 U.S.C. § 3204(a)(1), as the only responsible source with unique, classified knowledge of the specific aircraft’s configuration due to its prior involvement in U.S. Air Force modification efforts. NASA lacks the “need to know” for the classified details of the aircraft’s current status, and no other vendor possesses the technical expertise or access to perform the work without risk to national security or schedule integrity. Market research confirmed no viable alternatives, and while one other offeror, Reduced Gravity Solutions Inc., responded, it was deemed incapable due to lack of experience with this exact airframe. The performance location is in Ardmore, Oklahoma, where the aircraft is currently housed under USAF custody, and final acceptance is expected at NASA Armstrong Flight Research Center in Edwards, California. The contract is firm-fixed-price, with pricing determined through analysis under FAR 15.404-1, though the exact value is not disclosed in the justification documentation. No formal evaluation factors, line-item pricing, or detailed inspection criteria are provided, as competition is precluded by the unique qualifications of the contractor. The acquisition’s justification underscores a critical dependency on Denmar’s proprietary knowledge and the necessity for seamless transition from USAF to NASA custody to meet programmatic deadlines for Artemis mission readiness, with no mitigations for the inherent organizational conflict of interest being feasible or required.
