About the company
Jet Support Services, Inc. (doing business as JSSI), headquartered in Chicago, Illinois, operates as a prime contractor (93% of recent awards) providing aircraft maintenance, repair, and overhaul services—particularly for CF34 series jet engines, PT6A engines, and Bombardier Challenger 600 series airframes—exclusively to the Federal Aviation Administration under single-award indefinite-delivery contracts. JSSI competes in full-and-open procurements with no set-aside designations; the company is a for-profit corporate entity and parent to subsidiary Conklin & Dedecker Associates, Inc.
Customer concentration is absolute. JSSI serves three distinct federal agencies, but the Department of Transportation Federal Aviation Administration Headquarters accounts for 24 of 27 awards (88.9%) worth $148.9 million in combined potential value; the remaining two awards come from the Department of the Air Force Materiel Command Aeronautical Systems Center, and a single $103 thousand award from FAA Franchise Acquisition Services. JSSI holds no GWAC, BPA, or government-wide vehicle seats; all work flows through four primary FAA single-award IDIQs. The largest is the Bombardier Challenger 600 Series Aircraft Maintenance IDC (6973GH-25-D-00057), awarded September 11, 2025, with a $63.6 million ceiling through September 14, 2030, covering scheduled and unscheduled maintenance, aircraft-on-ground response, technical services, engineering support, and parts and tools rental. Two subsequent delivery orders under this IDC total $29.9 million (base year $19.3 million awarded September 12, 2025, and option year one $10.6 million awarded September 3, 2026, with performance through September 14, 2027). A second major vehicle, the CF34-3A1 Engine Overhaul IDC (6973GH-22-D-00096), carries $2.3 million and runs through March 14, 2025, with four task orders valued at $14.9 million for engine overhaul services. Two older IDCs (6973GH-19-D-00037 and 6973GH-20-D-00001) support cost-per-hour engine maintenance and produce six and five task orders respectively.
JSSI's recent award trajectory shows volatile activity: six awards in 2022, declining to three in 2023, recovering to five in 2024, then dropping to three in 2025 and one in 2026. Only one award ($10.6 million potential value) reaches ultimate completion within the next twenty-four months, presenting minimal recompete exposure in that window. The combined potential value across all 27 awards stands at $149 million, with $70.6 million obligated to date (47% drawn). Representative work includes a $10.6 million firm fixed-price delivery order for Challenger 600 maintenance (option year I, September 2026–September 2027), a $1.3 million purchase order for Challenger 605 landing gear overhaul (September 2025), and a $5.1 million labor-hour delivery order for CF34 engine overhaul (August 2024). Primary work location is Oklahoma City, Oklahoma, with secondary sites in Chicago, Illinois, Fort Worth, Texas, and subsidiary operations supporting the FAA's fleet of business jets and regulatory aircraft.
JSSI subcontracts to prime contractors in the defense supply chain. Two recent sub-awards, both dated November 21, 2024, place JSSI under Northrop Grumman Systems Corporation for Battlefield Airborne Communications Node (BACN) platform maintenance (classified as aircraft part and auxiliary equipment manufacturing). This marks JSSI's only material defense exposure; the sub-awards carry no dollar values in the source. Across its prime and sub portfolios, JSSI specializes in CF34 series turbofan engine maintenance and overhaul—the primary powerplant on the FAA's fleet of Bombardier Challenger business jets used for agency operations, technical missions, and emergency response.
