Federated PMA part library
A federation of approved manufacturers, MRO shops, airlines, and independent engineering firms could build a shared evidence layer for alternative aircraft replacement parts. The system would not bypass FAA approval; it would make the search, provenance, test evidence, eligibility, and service history of approved alternatives easier to audit and reuse.
Thesis
Bitcoin / decentralization role
Coordination mechanism
Verification / trust model
Failure modes
- • Airlines may prefer incumbent OEM-style supply relationships over lower-cost alternatives when aircraft downtime or liability risk is material.
- • A registry can improve discovery and evidence sharing, but it cannot eliminate the engineering cost of proving equivalency for complex or flight-critical parts.
Adoption path
- • Start with low-criticality, high-price replacement parts where PMA alternatives already exist or can be approved with bounded engineering evidence.
- • Expand into a multi-party eligibility and provenance network used by MRO procurement teams, insurers, and approved manufacturers.
