Everyone else brings technology to aviation.
We bring aviation into technology.
Every feature and workflow comes from someone who's done the job for 25 years. We don't guess what a mechanic needs — we build what we've needed a thousand times.
We don't show up to extract. We show up to build together. The best solutions come from people who actually do the work having a seat at the table.
Every repair is documented. Every decision is data-driven. Every project is managed with precision. No surprises, no hidden costs, no gaps in the record.
We leverage modern tracking systems and digital workflows to provide better visibility, more accurate records, and data-driven insights for every aircraft we touch.
We build at the speed of right — not the speed of shortcuts. Marine Corps discipline applied to every inspection, every repair, every sign-off.

OnChain Aviation was founded by Mike Brown — a 25-year aviation maintenance veteran, USMC combat vet, and large-cabin Gulfstream specialist who's had his hands inside every model from the G450 through the G700.
"Autograph your work with excellence."
From F/A-18 Hornets at MCAS Beaufort and Iraq to two decades at Gulfstream Aerospace in Savannah — Mike recognized a gap in the market. Gulfstream operators needed more than technical expertise. They needed a maintenance partner who understood operational discipline, digital-first documentation, and the future of where this industry is headed.
The name "OnChain" represents a commitment to accountability, traceability, and reliability at every link in the maintenance chain. From initial diagnosis to final documentation — rigorous standards and transparent communication on every engagement.
While we deliver exceptional Gulfstream maintenance today, we're pioneering the future of aviation operations — blockchain-verified records, AI-powered diagnostics, and digital aircraft identities.
Immutable, tamper-proof maintenance records that eliminate the trust gap. Every inspection, every part, every compliance action — cryptographically verified and permanently recorded.
Capturing decades of tribal knowledge in AI tools that compress the learning curve. Senior expertise that doesn't retire — it multiplies across the next generation.
Decentralized identity systems for aircraft that create auditable chains of custody. Counterfeit-proof part tracking and interoperable data layers for the entire maintenance ecosystem.
Every repair done right. Every diagnosis thorough. Every recommendation grounded in deep technical knowledge and 25 years of pattern recognition.
Clear timelines. Transparent budgets. Proactive communication. Detailed documentation. Marine Corps–grade rigor on every engagement.
Your operational needs drive our approach. We're not just maintaining aircraft — we're supporting your mission, whether it's business, personal, or charter.
