Back-to-birth parts ledger
Hypothetical. Not a client, not a result.
// The problem
An airline, its maintenance shop and a parts broker each hold part of a rotable component's history, and one missing release certificate in the chain can leave a serviceable part unusable.
// What we would build
A private permissioned ledger where the airline, the shop and approved suppliers record installations, removals, shop visits and the release certificate for each, such as a Transport Canada Form One or an FAA Form 8130-3, against the part's serial number. The history becomes one record no party can quietly change, and gaps show at once. If all the records sit with one company, its maintenance system already does this job.
// What is in it
- Each serialised part's installations, removals and shop visits recorded
- Release certificates attached at every shop visit
- Gaps in the history flagged before a part is installed
- Smaller suppliers and brokers write through a portal, with no software of their own to run
- Export of a part's full history for a buyer, a lessor or an inspector
