What to Look for in a Maintenance Partner During an AOG Event
A true professional maintenance shop proves itself during an Aircraft On Ground (AOG) event. The right partner responds with urgency, communicates clearly, and understands that downtime is not just a mechanical issue, but an operational one. The best shops will respond to an AOG event within 1 hour.

An AOG event will tell you very quickly whether you are working with the right shop or not. What separates a true professional shop from an average one often shows up the moment an airplane goes down unexpectedly.
If the shop has a real sense of urgency, communicates well, and keeps the right parts on the shelf, that is who you want to work with. If, on the other hand, you are calling to get help and it takes hours just to hear back, then another day or two goes by before anyone really looks at the airplane, and then more delay happens because they are waiting to source parts or waiting on approvals, that usually tells a lot about how that shop operates.
Those delays are often not just about maintenance skill. A lot of the time they come from weak systems, weak communication, and a lack of experience operating in a high-production environment. That is one of the reasons AOG events are so revealing. AOG is where weak systems get exposed, and weak shops do too.
"A true professional maintenance shop proves itself during an AOG event. The right shop responds with urgency, communicates clearly, keeps common failure parts on hand, and understands that downtime is not just a mechanical issue. It is an operational issue that affects scheduling, customer experience, and revenue."
Chris Schoensee, Owner & President, Paragon Flight TrainingMany maintenance providers are used to dealing with private owners who may fly once or twice a month. In that world, the urgency often feels lower. The airplane is down, but it may not be disrupting ten flights a day, a student’s only lesson that week, a club member’s reservation, or an operator’s customer experience.
Flight schools, rental operators, and clubs live in a different environment. For them, downtime is not just an inconvenience. It affects dispatch reliability, training momentum, customer satisfaction, and revenue. That is why the right maintenance partner needs to understand more than the repair itself. They need to understand the operational consequences of the airplane being down.
Why Paragon Flight MX is Different
Another issue is that many larger shops are naturally drawn toward bigger aircraft and bigger jobs. Bigger aircraft often mean bigger repair orders and more revenue. So if a piston single like a Cessna, Piper, Cirrus, Bonanza, or Baron comes in with an AOG issue, it may not get the same attention if the shop is triaging its workload around larger or more lucrative jobs. That is reality in a lot of places.
The result is that the smaller piston airplane can end up sitting, not because the problem is especially difficult, but because it is not at the top of the shop’s priority list.
At Paragon, we think about that differently because we are a flight school ourselves. We understand uptime. We understand what a grounded airplane does to the day. We understand that one maintenance delay can ripple into canceled lessons, frustrated customers, broken schedules, and lost opportunity.
That mindset is why we put such a strong focus on being prepared for AOG events. One of the biggest ways we do that is through inventory. We keep a lot of common AOG parts on the shelf. If you are operating common piston aircraft like a Piper Archer or a Cessna 172S, there is a good chance we already have many of the higher-failure items sitting here ready to go. Things like batteries, starters, alternators, and other common components are already on the shelf because we use them in our own fleets.
That means when an AOG happens, we are not starting from zero. We are not first realizing what failed, then calling around, then waiting on shipping for basic parts that should have been anticipated in the first place. Prepared shops move faster because they reduce delays before the wrench even turns. That is one of the biggest differences between a shop that handles AOG well and one that struggles with it.
Another thing we do for repeat customers is stock parts specifically for them when the relationship makes sense. If a customer is working with us consistently and we know what their fleet or aircraft commonly needs, we are willing to invest in that relationship by keeping the right items on hand for them as well. That is not an added cost to them. It is part of how we support the relationship. As trust builds both ways, we are willing to invest in helping them stay up and running because that is what a real maintenance partnership should look like.
At the end of the day, AOG support is not just about fixing airplanes. It is about urgency. It is about communication. It is about preparation. It is about having the right parts, the right mindset, and the right systems in place to minimize unnecessary downtime. That is where you find out whether a shop is really built to support operators who depend on their airplanes.
Key Takeaways for AOG Maintenance
- **Urgency is Paramount:** A professional shop responds quickly, ideally within 1 hour, to an AOG event.
- **Clear Communication:** The best partners provide transparent updates and manage expectations effectively.
- **Prepared Systems:** Look for shops with robust internal processes and a strong inventory of common failure parts.
- **Operational Understanding:** The ideal partner recognizes that downtime impacts scheduling, revenue, and customer experience, not just the aircraft.
- **Piston Aircraft Priority:** Ensure the shop prioritizes AOG events for common piston aircraft over larger, more lucrative jobs.
- **Proactive Parts Support:** A strong maintenance relationship includes the shop's willingness to stock specific parts for repeat customers.
Common Questions About AOG Maintenance
A professional maintenance shop should respond to an AOG event with urgency, ideally within 1 hour, to assess the situation and begin communication. Delays in initial response can indicate weak systems or a lack of understanding of operational impact.
An AOG-ready shop, especially one supporting common piston aircraft like Cessna 172s or Piper Archers, should keep a significant inventory of high-failure items on hand. This includes parts like batteries, starters, alternators, and other common components to minimize delays in repair.
For flight schools, rental operators, and clubs, aircraft downtime is not just a mechanical issue; it's an operational one that affects dispatch reliability, training momentum, customer satisfaction, and revenue. A good maintenance partner understands these consequences and prioritizes minimizing downtime.
Proactive AOG support includes maintaining a robust inventory of common parts and, for repeat customers, stocking specific parts tailored to their fleet's needs. This investment in the relationship helps reduce delays before a wrench even turns, ensuring aircraft stay operational.
No, many larger shops are naturally drawn toward bigger aircraft and more lucrative jobs. This can mean that AOG issues for smaller piston singles like Cessnas or Pipers may not receive the same immediate attention, leading to longer downtimes for operators of these aircraft.
A true professional maintenance shop during an AOG event is defined by its urgency, clear communication, preparedness (especially with parts inventory), and a deep understanding of the operational impact of downtime on its clients. They prioritize minimizing delays and getting aircraft back in the air swiftly.
