AOG refers to an urgent situation where an aircraft is grounded due to technical issues and cannot return to service until the required parts or repairs are completed. Every minute an aircraft is grounded, airlines lose thousands in revenue and face reputational risks.
Aircraft on Ground (AOG) is a critical term in aviation maintenance that describes an urgent situation where an aircraft is grounded due to technical faults or part failures, rendering it unable to return to service until the necessary repairs or replacement parts are procured and installed. This scenario demands immediate attention because every minute an aircraft remains on the ground translates to significant operational and financial losses for airlines, as well as potential disruptions to flight schedules and passenger inconvenience.
When an aircraft is grounded, the consequences ripple across multiple facets of airline operations:
AOG logistics is a specialized branch within aviation supply chain management focused exclusively on minimizing downtime by expediting the delivery of critical spare parts and components. The complexity lies in:
Speed and Precision: Locating the exact required parts quickly, sometimes across continents, and ensuring their rapid delivery through the fastest possible routes (air freight, courier, etc.).
Coordination: Seamless communication and coordination between maintenance teams, suppliers, logistics providers, and airline operations control centers.
Global Network: Leveraging a network of certified vendors, warehouses, and transport services to source and deliver parts anywhere in the world, often on short notice.
Modern AOG logistics employ advanced tools and strategies to streamline the process:
Real-Time Inventory Management: Integrated IT systems track part availability and location globally, reducing search time.
Predictive Maintenance: Data analytics and IoT sensors help forecast failures, allowing proactive part stocking to avoid future AOG situations.
Dedicated AOG Teams: Specialized personnel handle AOG incidents 24/7 to coordinate rapid response.
Strategic Warehousing: Positioning critical parts in regional hubs close to major flight routes for quicker access.
Effective AOG logistics is vital for maintaining airline operational integrity, financial health, and customer satisfaction. By optimizing the supply chain and response mechanisms, airlines can drastically reduce aircraft downtime, ensuring that grounded planes return to the skies as swiftly and safely as possible.
