About the company
SAM Kantimathi, doing business as Fatigue Concepts, is a sole proprietorship minority-owned and self-certified small disadvantaged business that operates as a prime contractor delivering specialized aviation safety and maintenance training to the Federal Aviation Administration, competing on a full-and-open basis without set-aside designations. Based in El Dorado Hills, California, Fatigue Concepts holds three single-award Indefinite Delivery Contracts with FAA Headquarters valued at $311,124, $198,962, and $127,007 respectively, and has generated approximately $2.7 million in combined potential value across 57 prime awards since 2001, with $1.1 million obligated to date.
Fatigue Concepts specializes in three core technical training programs for FAA personnel: Aircraft Structures for Inspectors (covering structural design, fasteners, repair methods, and inspection techniques), Reliability and Probability training (focused on probabilistic risk assessment, damage tolerance analysis, and fatigue management), and Maintenance Steering Group (MSG-3) training addressing aircraft maintenance program development and analysis. All instruction is delivered at the vendor's El Dorado Hills facility and targets FAA aviation safety inspectors and maintenance personnel. Representative recent awards include a $198,962 delivery order (fourth option year) for reliability and probability training running through September 2026, a $311,124 single-award IDC for aircraft structures training through February 2027, and multiple $11,500 to $25,378 delivery orders for MSG-3 and aircraft structures courses executed across 2024 and 2025.
Customer concentration is extreme and single-agency dependent: the Department of Transportation Federal Aviation Administration Headquarters accounts for 46 awards and $2.3 million (85% of combined potential value), with the FAA Aeronautical Center placing an additional 5 awards valued at $329 thousand. Nominal exposure to NASA and Department of Defense customers (one or two awards each) does not materially broaden the customer base. The vendor operates exclusively under three FAA single-award IDVs — contract 6973GH-21-D-00058 for reliability and probability (10 task orders, $550 thousand), contract 6973GH-19-D-00064 for MSG-3 training (15 task orders, $173 thousand), and contract 6973GH-21-D-00060 for aircraft structures (5 task orders, $122 thousand) — generating consistent recurring task order flow. Activity peaked in 2022 with eleven awards and has declined to one award in 2026 year-to-date, though this reflects a narrow snapshot; the recompete cliff shows three awards ($236 thousand combined potential value) completing within the next twenty-four months. The vendor holds no subcontract work — the entire footprint is prime contractor delivery of training services classified primarily under NAICS 811211 (Other Technical and Trade Schools).
