Aircraft on Ground (AOG): Delivering Critical Turbine Spares in Under 6 Hours
Executive Summary

Key Takeaways

  • An Aircraft on Ground (AOG) event costs airlines between $100,000 and $250,000 per hour in passenger compensation and gate fees.
  • Dedicated AOG desks maintain 24/7 direct tarmac access, emergency customs pre-clearance, and 90-minute charter mobilization SLAs.
  • On-Board Couriers (OBC) carry critical avionics components as hand-carry baggage on immediate commercial passenger departures.
  • Custom shock-absorbing crating and certified air-ride logistics protect delicate turbine blades and radar guidance systems from vibration damage.

The High-Pressure Economics of Aerospace Grounding

When a wide-body commercial airliner experiences an unexpected technical fault at an international airport, every single minute required to source and deliver a replacement component carries massive financial implications.
