When an aircraft is grounded due to a technical failure, the impact is immediate: cancelled flights, affected passengers, rising costs, and regulatory pressure. In this context, AOG logistics is one of the most demanding operations in aviation—and DUX Logistics operates in this field as a core specialization, not an exception.
In this article, we explain what AOG is, how critical logistics works in these situations, and how DUX manages these operations on a global scale with immediate response and execution under pressure.
What is AOG in aviation?
AOG (Aircraft on Ground) is the condition in which an aircraft is unable to operate due to a technical failure, lack of a critical component, or regulatory non-compliance. It is classified as the highest operational priority in both commercial and business aviation.
Direct impact of an AOG event
An AOG event is not just a technical issue. It creates a cascading effect that includes:
- flight cancellations or rescheduling
- direct impact on passengers and crew
- costs related to maintenance, repositioning, and accommodation
- revenue loss due to aircraft downtime
- risk of regulatory non-compliance
For this reason, resolving an AOG situation is treated as the highest priority by operators, MROs, and airlines.
How AOG logistics works
AOG logistics operates under a completely different logic compared to conventional logistics. Time is the critical factor, and every step is designed to eliminate delays.
What makes AOG logistics different from traditional freight
- Lead times measured in hours, not days
- Priority and dedicated transport with guaranteed capacity
- Simultaneous coordination across multiple international agents
- 24/7 availability, regardless of business hours
- Cost as a secondary factor compared to aircraft availability
The goal is simple: deliver the right part in the shortest possible time, directly to where the aircraft is grounded.
How DUX Logistics executes AOG operations in practice
DUX Logistics handles AOG operations on a global scale, continuously managing critical shipments for the aviation sector. Hundreds of operations are executed for airlines, business aviation operators, MROs, and offshore helicopter operations, across multiple countries and time zones.
Types of aviation cargo handled
- Complete aircraft engines
- APUs (Auxiliary Power Units)
- Rotating components
- LRUs (Line Replaceable Units)
- Critical parts for corrective maintenance
- Reverse logistics of removed components
Transport modes used in AOG operations
- Next Flight Out (NFO): shipment on the first available flight with cargo space, regardless of airline
- Onboard Courier (Hand Carry): personal transport by a dedicated courier for small, high-criticality parts
- Dedicated charter: exclusive aircraft used when other options cannot meet required timelines
Each operation includes immediate pickup, priority transport, and direct delivery to airports, hangars, or maintenance facilities.
Technical and regulatory requirements in AOG logistics
AOG operations are not only about speed—they require full compliance with aviation technical, documentary, and customs regulations. Missing any of these elements can compromise the entire operation.
Aviation documentation and compliance
- Documentation aligned with FAA and EASA standards
- Validation according to operator and MRO requirements
- Full traceability and chain-of-custody control
- Component historical records
- Compliance with ANAC regulations
Emergency customs clearance in AOG operations
In AOG logistics, customs clearance is often the main time bottleneck. DUX Logistics is certified under Brazil’s OEA (Authorized Economic Operator) program, which enables simplified procedures and priority handling for imports. In emergency aviation scenarios, this provides a real operational advantage.
Applicable customs regimes include:
- Transit customs declaration (DTA)
- Temporary import regimes
- Specific frameworks for aviation components
Controlled storage for aviation components
Beyond transport, DUX Logistics also operates controlled storage solutions for aviation cargo, ensuring:
- physical integrity of components
- documentation preservation
- readiness for immediate re-shipment
- strict control of time and status
For high-value and highly critical parts, this level of control is essential—especially in multi-stage operations or when waiting for flight availability.
Who AOG logistics is designed for
DUX AOG services are intended for organizations where aircraft downtime creates immediate operational and financial impact:
- Commercial and regional airlines
- Business aviation operators
- Air taxi companies
- Offshore helicopter operations
- MROs and maintenance facilities
- High-criticality aviation operators
If a grounded aircraft generates direct losses, AOG requires specialized logistics—not standard freight forwarding.
24/7 AOG Desk: dedicated support for critical operations
AOG does not follow business hours. DUX Logistics operates a dedicated response team for critical situations, with immediate action, international coordination, and real-time tracking from dispatch to final delivery.
In AOG operations, silence costs money. Communication is continuous at every stage.

Frequently asked questions about AOG logistics
What does AOG mean in aviation?
AOG stands for Aircraft on Ground: a condition in which an aircraft is unable to operate due to technical failure, missing critical parts, or regulatory non-compliance. It is the highest operational priority in aviation.
How does AOG logistics work?
AOG logistics relies on priority transport, immediate response, and multi-agent coordination to deliver parts directly to the aircraft within hours. Common solutions include Next Flight Out (NFO), Onboard Courier (Hand Carry), and dedicated charters.
Who provides AOG logistics in Brazil?
Specialized critical logistics providers such as DUX Logistics perform full AOG operations in Brazil, including international transport, emergency customs clearance, and final delivery. DUX’s OEA certification provides a concrete advantage for urgent imports.
What is the difference between AOG logistics and conventional freight?
Conventional freight is schedule-driven and cost-focused. AOG logistics is time-critical, operates 24/7, and prioritizes aircraft availability over cost. The structure, methods, and teams involved are fundamentally different.
What is Next Flight Out (NFO)?
Next Flight Out (NFO) is a transport method where cargo is booked on the first available flight with capacity, regardless of airline. It is widely used in AOG due to its balance between speed and cost compared to charter flights.
What is an Onboard Courier (OBC)?
An Onboard Courier (OBC), or Hand Carry, is a dedicated courier who personally transports aviation parts as carry-on baggage. It is used for small, highly critical components when cargo space delays are not acceptable.
