In Case of Emergency


In Case of Emergency

The very definition of “emergency” is a serious, unexpected, and often dangerous situation requiring immediate action. Emergencies are not planned and most often are very unwelcomed. In aviation, the dreaded Aircraft On Ground (AOG) is one such emergency situation.

Any maintenance problem that occurs in or away from the hangar that keeps an aircraft on the ground, thus inaccessible to those who need it, requires immediate attention and quick response. Duncan Aviation has the processes and the tools to ensure quick response when you’re dealing with an AOG.

AOG “One-Call” Service

One call to 877.522.0111 makes all of Duncan Aviation’s services available to you 24 hours a day, seven days a week. With airframe and engine factory authorizations from the major OEMs, we are able to service most AOG situations in the field so that you can get back in the air and back on schedule. A crew can be on the road or in flight headed to your destination within hours of your call.


Strategically located across the United States are eight specialized Rapid Response teams. They are called upon daily to assist operators who land at airports with little to no capacity for service, but need a quick response for getting back in the air if a problem arises. These teams have authorizations on all major OEM engines and APUs including: Honeywell, Pratt & Whitney, GE and Williams. Capabilities in-thefield include troubleshooting, repair, line replaceable unit (LRU) and engine changes.


Engines are not the only aircraft system that may require emergency service while the aircraft is away from home base. Airframe issues often arise. AOG airframe issues are serviced out of Duncan Aviation’s major repair facilities located in Battle Creek, Michigan; Lincoln, Nebraska; and Provo, Utah. With factory authorizations from all the major business aviation OEMS, qualified technicians are available to be dispatched anywhere in the world.

Avionics Installation

Duncan Aviation also has a highly mobile network of avionics satellite locations positioned at more than 25 of the busiest business airports across the United States. They are specialized in AOG situations and can get to just about anywhere you happen to land, live or hangar your aircraft to diagnose your avionics system squawk and get you flying again. Our capabilities include the latest in test equipment for fast and accurate squawk analysis and repair of avionics malfunctions on board the aircraft.


Not every AOG situation requires the dispatching of a team. Sometimes, operators need a quick response for an exchange, loaner, repair or overhaul. One call to 800.228.1836, also gets you instant emergency parts service. Duncan Aviation maintains a large and growing inventory of exchange and rotable units (more than $45 million) available 24/7/365.

AOG “Anywhere” Services

Duncan Aviation may be based in the United States, but we offer global service, touching nearly every continent. Technicians have serviced Challengers in Egypt, Falcons in Europe and Learjets in Brazil. We’ve performed maintenance on engines in Japan, Venezuela and Canada; and we have sent emergency exchange parts to Newfoundland, New Zealand and Hong Kong, among many other locations.

AOG Technical Support

Sometimes an AOG situation can be solved with a phone call to the right individual who is trained to ask the right questions. Duncan Aviation has 24 highly skilled and specialized technical representatives available for one-on-one phone calls to help you get to the bottom of what is keeping your aircraft on the ground. They are experienced and respected as industry experts and they are called upon to troubleshoot problems in all areas surrounding business aircraft ownership. Many have been invited by OEMs to participate in setting industry standards.

AOG Mobile Application

Duncan Aviation has launched a new AOG Service app that makes it easy for AOG operators to find the Duncan Aviation location that is nearest to their current position. It lists all 24/7 emergency phone numbers and technical representative contact information. This app is currently available for Apple® devices, and an Android version is planned for later this year. Visit www.DuncanAviation.aero/apps for more information.

At Duncan Aviation, we address your needs so you can operate your aircraft specific to your situation. It is not unusual for us to dispatch our own aircraft to expedite AOG repairs, ferry parts and, if necessary, transport passengers to their next destination. Duncan Aviation is truly a one-stop shop. When you are AOG, all you need to remember is Duncan Aviation will find a way to solve your problem.
