No, blockchain still doesn't fit, because there's no reason to allow random keypairs to write to the network. The condition for writing to the database is whether your key is on a list of real vendors; the whole hashing/longest chain dance is superfluous.

Merkel trees with restricted access are probably the more applicable notion here. E.g., what most Free Software development uses.

I like how OP jumps from “highly regulated world of aircraft” to a solution with zero regulation. Imagine being on a sinking ship and the captain is all; don’t worry, if we tie this life jacket to the handrail, it’ll stop the descent by floating on top of the water. IT has been taken over by the rent seeking industrial complex. Peddling hallucination to prop up book sales and conference travel.

  I dont know why we are even bringing IT into the A&P world other than dissemination of maintenance data. Aircraft maintenance has been well documented for almost a century now. The issue is incorporating other entities before they are vetted for corruption. This is a sad state of affairs. Edit: thinking about that, planes crash all the time but it is rare, but non-zero, due to maintenance

Blockchains can be public or private (i.e. restricted access). In this case, the latter would be appropriate. There are also ways of signing records to establish that a known company produced them. The idea behind using blockchain for tracking provenance is that you can check if a widget with unique serial number number X has been produced, who currently possesses it, and whether it has already been used. It would also be possible for each manufacturer to maintain their own record, so blockchain is not the only solution, but it is a fairly good fit to this particular problem. As with manufacturers maintaining ownership records, it cannot absolutely prevent a counterfeit part being used, but since the part would have to come from the company who was the last holder of record for a specific genuine part, and the record for that genuine part would be marked as "consumed", normally there would be no financial motive to supply a counterfeit. (Supply to Russia might be a an exception).
