Threshold Aviation

What Threshold Aviation does

Threshold Aviation Group is a privately held, DiLullo-family-owned full-service aviation services company operating since 1985 with two fixed-base operator (FBO) locations at Chino Airport (KCNO) in Southern California and Auburn Municipal Airport (KAUN) in Northern California. The business is structured around a unified platform spanning FBO services, aircraft maintenance, charter, management, sales, storage, cargo handling, asset recovery, and interior completions, targeting enterprise and mid-market business jet owners/operators with a one-stop-shop go-to-market model. Customer concentration sits in general aviation with long-tenured relationships (multiple customers of 10-25+ years), supported by direct field sales across divisions and a lower-priced inland cost structure positioned against coastal competitors.

Core technical capabilities center on Aviation Maintenance Group (AMG), an FAA Part 145 Approved Repair Station (Certificate VUXR007X) equipped with machine shops, upholstery, and wood shops enabling heavy maintenance and major repairs on large and small business jets (Gulfstream, Challenger, Falcon, Lear Jet, Citation). Companion units include TAG Global charter (ARG/US Gold Certified, operating a Gulfstream G550/V fleet), Jet Park commercial aircraft storage (capacity for 100-150 aircraft), and Cielo Blu (Tecnam aircraft sales/maintenance JV). Infrastructure spans approximately 250,000 sq ft of hangar, office, and shop space and 500,000 sq ft of ramps at Chino, with 40,000- and 36,000-gallon fuel farms at KCNO and KAUN respectively.

The revenue model is multi-stream and predominantly services-based: transactional fuel sales (1M+ gallons/year at KCNO), professional services (maintenance labor, parts, interior completions, asset recovery), managed services (aircraft management fees), transaction fees (charter hourly, aircraft brokerage - 50+ aircraft flipped over 15 years), and subscription/recurring storage fees (Jet Park). Pricing is transparent for fuel (unit pricing per gallon, posted on website), while maintenance and charter follow industry-standard hourly/contractual models. The only disclosed revenue point is ~$12M gross annual sales in 2016 (with a stated 10% growth expectation); no subsequent financials are publicly available.
