Airlines pooled spare parts instead of each stocking them twice
The IATP lets 111 airlines share 9,088 aircraft parts, so a member rents a spare for $27k a year instead of buying it for ~$450k.

the move
Airlines keep ~$1.6 million of parts per aircraft to avoid a grounded plane, yet much of that inventory sits idle. In the days of regulation, carriers treated each other as rivals and hoarded spares.
Airlines began sharing in 1948, and the IATP grew into a non-profit that organizes parts into pools by aircraft type. It now has 111 members sharing 9,088 parts valued at over $265 million, facilitated by ~29 associate members who hold, maintain and deliver the parts.
The payoff is turning a $450k purchase into a ~$27k annual fee. Members still need civil-aviation approval and audited procedures, so the pool runs on trust plus process, not on a handshake.
why it works
- A shared reserve is far smaller than the sum of individual reserves.
- Renting a rare part beats buying it to use once a year.
- The pool only works if members follow inspection and record-keeping rules.
what transfers
When a few parties all keep reserve capacity for the same rare event, they can share one pool rather than each paying for idleness.
what came after
Industry and regulatory shifts made pooling normal; the IATP broadened from parts into line maintenance, ground equipment and aircraft-recovery kits. As supply chains tightened after 2020, pooling and load-sharing solutions grew again as a way to quickly resolve aircraft-on-ground situations.
