About
Paper logbooks have a failure mode.
We fixed it.
Paper logbooks go missing during aircraft sales. Unsigned entries become legal disputes. Binders fill up with entries in six different handwriting styles. None of this is usually malicious — the system just has no guardrails.
FAR 43.9 is specific about what a maintenance record must contain. It's not a suggestion. But nothing in the regulation required those records to be tamper-evident, verifiable, or auditable after the fact. Paper is easy to alter and impossible to prove unaltered.
myAviationTools is built to close that gap. Append-only records with SHA-256 chain integrity. Mechanic signatures that carry the mechanic's certificate number, which anyone can look up on the FAA Airmen Inquiry. Maintenance history that is hash-sealed today, with anchoring to a public blockchain (Ethereum Sepolia testnet first) rolling out — not because it's trendy, but because it means anyone with a block explorer will be able to verify the chain without trusting us.
Mission
Make tamper-evident maintenance records the default for general aviation — not a feature only Part 145 stations with six-figure software budgets can afford. Every owner-operator, every independent A&P, every small shop should have the same audit trail as the majors.
