End AOG Delays: Modern Procurement Strategies for Aviation Maintenance Teams

For aviation maintenance teams, few challenges prove to be more disruptive or costly than an Aircraft on Ground (AOG) situation. When an aircraft is grounded as a result of a critical component failure or outstanding issue, every passing hour translates into lost revenue, operational setbacks, and potential strain on customer trust. Therefore, in an industry where reliability and punctuality define success, effective AOG management goes beyond being a goal, becoming an absolute necessity for success.

Today, maintenance organizations are increasingly turning to advanced procurement strategies and digital tools to eliminate inefficiencies and improve sourcing speed, the utmost goal being to prevent AOG events from occurring in the first place. To help you in your own initiatives and operations, read on as we discuss the most common causes of AOG delays and outline key strategies maintenance teams can adopt to minimize downtime.

The Most Common Causes of AOG Situations

While not common, AOG events may arise from a range of issues across component health and maintenance practices. Generally speaking, the following are the most common causes that operators face.

• Unexpected Component Failure: Even with strict adherence to regular inspections and proper care, the sudden malfunction or failure of various parts can lead to a plane being grounded for servicing.
• Insufficient Inventory: Lacking critical spare parts or having limited access to more niche components may prolong repair times.
• Procurement Inefficiencies: Delayed supplier responses, limited part traceability, and mismanaged sourcing workflows can all hinder timely resolution.
• Supply Chain Disruptions: Global shortages, customs delays, and transportation bottlenecks are all becoming increasingly common across the globe, potentially extending lead times unexpectedly.
• Regulatory and Certification Challenges: Operators may face delays if they are unable to secure certified and compliant parts for re-entry into service.
  

While it is impossible to eliminate every risk factor, modernizing and adapting one’s aviation procurement strategies can offer a means to drastically reduce AOG frequency and duration.

Proactive and Predictive Maintenance Practices to Prevent AOG Events

Proactive maintenance planning is a key element of preventing downtime, as it allows teams to replace components before they fail. A major element of proactive practices is optimizing predictive maintenance, which is the approach of using real-time data analytics to identify early signs of component degradation.

Common Predictive Measures

• Data-Driven Monitoring: Leveraging advanced sensors and maintenance tracking software, technicians can collect and analyze performance data to determine when servicing is necessary.
• Scheduled Part Replacements: It is always recommended to follow OEM-published replacement intervals for time-sensitive parts like actuators, filters, and avionics modules.
• Failure Trend Analysis: Be sure to track the lifespan and performance of important assembly items to identify potential patterns that indicate failure risks.
  

By integrating predictive systems into maintenance workflows, operators can schedule repairs during planned maintenance checks, rather than reacting to failures during operations.

Prioritizing Inventory Management for Critical Parts

Maintaining a well-structured inventory is central to avoiding AOG situations, though it is important that one does not fall into the trap of tying up capital in excessive stock or facing delays as a result of insufficient inventory. With this in mind, the goal is to find a balance of needs by identifying the most critical components for continuous readiness.

Important Elements of Modern Strategies

• Establish Tiered Part Categorization: As you create a strategy, try to classify inventory based on criticality, usage frequency, and average lead time.
• Focus on High-Turnover Components: Stock essentials like filters, hardware and fasteners, actuators, and sensors that are frequently replaced across multiple aircraft types, preventing the risk of a delay.
• Regularly Audit and Cycle Count: Periodic reviews can help in identifying obsolete stock and promote more accurate inventory tracking.
  

Build a Dedicated AOG Response Team

Beyond identifying parts of need, the difference between a short delay and a prolonged outage also comes down to response capability. As such, a dedicated AOG response team is important to promote efficient coordination and logistics.

The Core Elements of an Effective AOG Team

• 24/7 Support: With around-the-clock support, global operations can be safeguarded with immediate responses to AOG situations.
• Direct Supplier Communication: Establish fast access to distributors with immediate stock and logistical support to hasten fulfillment.
• Integrated Logistics Management: Create and train teams that are capable of coordinating courier services, customs clearance, regulatory documentation, and other needs.
  

These teams are critical, as they act as the bridge between maintenance crews, procurement specialists, and supply chain partners to expedite recovery.

Strengthening Partnerships for Reliable Fulfillment

Working with experienced distributors and suppliers can make the difference in one’s AOG-prevention strategies, facilitating consistent access to common and specialized civil aviation parts that may be required for rapid repair operations.

The Importance of Strong Industry Relationships

• Access to Verified Inventory: Partnering with a reputable distributor will better guarantee that any purchased components meet industry standards and regulations.
• Reduced Lead Times: Those with large, strategically located warehouses or extensive inventory offerings can often fulfill urgent orders quickly.
• Traceability and Certification: Reliable distributors will provide documentation as necessary with every shipment to ensure regulatory compliance and airworthiness.
• Scalability for Different Needs: Whether sourcing a single bolt or a complete avionics system, strong partnerships will allow more flexibility across orders.
