Why AOG drags
When an aircraft is on the ground it cannot fly until the failed part is sourced, fitted, and signed off. Long-lead castings and component obsolescence on aging fleets stretch the sourcing, not the wrench time, so the part finds the schedule, not the other way round.
See demand and obsolescence early
Turnaround time runs from shop induction to return to service, and aircraft-on-ground time is costed by the hour, which is what justifies safety stock on at-risk parts. Standard parts data under ATA Spec 2000 lets you find, order, and trace a replacement across the network without manual reconciliation.
Where the ERP closes the loop
On Hudace, maintenance and inventory share one view of part demand, stock, vendor lead times, and serialized history, so Xenon AI forecasts which components trend toward failure or obsolescence and recommends safety stock and last-time buys, pre-positioning long-lead items.
A planner or reliability engineer approves every buy. AI surfaces the demand signal and the obsolescence horizon; it does not commit spend.
The numbers to watch
The sourcing portion of turnaround is the part to attack.
Turnaround time
Induction to return-to-service. The headline MRO measure.
AOG hours
Hours an aircraft is grounded for parts. Costed by the hour.
Spares fill rate
Demands met from stock / total. Low fill drives expedites and downtime.
Obsolescence exposure
Parts trending to end-of-life without a compliant source. The future AOG risk.
