Aircraft Landing Gear Repair & Overhaul Is Not a Commodity Service

Posted by Diane Heiserman on Wed, Dec 07, 2016 @ 08:00 AM

An aircraft can't go anywhere without its legs. Landing gear are an integral part of the whole operation, yet their overhaul and inspections are more often viewed as something that is taken care of behind-the-scenes; scheduled alongside, but taking a backseat to, a major airframe inspection. Yet, it can have a huge impact on the entire project's schedule if the restoration runs into major squawks.

So who’s taking care of your aircraft’s legs?

landing-gear_blog.jpgAlthough landing gear overhaul and repair services are not available from everyone from coast-to-coast, it has a bit of a reputation of being a commodity in the business aviation industry. There are almost too many choices on where to send your gear when it comes time for inspection.

It is fair to think with FAA regulations, Chapter 5 requirements, and access to the same maintenance manuals, that all facilities are equal. You would be wrong.

In reality, landing gear overhauls are not created equal, and there are often many differences among the maintenance facilities and the quality of work performed, and out-the-door price.

So how do you decide? Let’s begin with what’s most important to you.

Landing-gear-shop-full.jpgAsk nearly every aviation service sales person what the top deciding factor is for their customers when choosing an MRO for service and they will tell you Downtime.

No one looks forward to having their aircraft down for inspection. Time is money and your aircraft needs to be available at all times. That is why your time requirement is one of our requirements.

At Duncan Aviation, we continually examine our processes to find more efficient avenues to deliver landing gear faster. However, we will never sacrifice quality or safety for the sake of time.

In 2015, our landing gear shop met quoted turn times a near perfect 98% of the time on scheduled, complete landing gear sets. In 2016, we are on track to improve that number even further thanks to a more efficient process and interactive calendar.


When it comes to overhauling, inspecting, and repairing landing gear assemblies and subassemblies, we’ve been doing it since 1978. The shop started out modestly as a bench at the back of our main hangar but has since grown to a 6,000-square-foot facility equipped with an overhead crane, dedicated paint booth, and cure room.

Are we the largest landing gear shop in the industry? Possibly not, but to the nearly 500 operators who rely upon us each year, we are big enough.

With capabilities on more than 50 different make/model aircraft and 3,143 unique landing gear parts, we’re confident we’re big enough for you, too.

By the very definition, a warranty is a promise of continued support and service even after the project is over. We believe so highly in our own work, that our warranties cover everything. Parts, labor, and not just our work, but the work of others...covered.

I know what you’re thinking! How can Duncan Aviation possibly offer a warranty on work they didn’t perform?

It’s simple. Through our experience, we’ve been able to identify high-failure parts and will take the extra time during overhaul to make sure those parts are able to last.

We think we’ve done a pretty good job at it because our warranty claim rate in 2015 was less than 1%, 0.6% to be exact.


Although price is likely not the most important factor in your buying decision, it still is an important one. That is why we offer three different pricing structures to fit your budget requirements.

Firm Fixed. Before your gear gets to Duncan Aviation, you will know what you are paying. Firm Fixed guarantees one price with no bill-back, regardless of the condition of the gear. We have heard from several operators who chose a lower-cost provider that with additional billing based on the gear’s condition, their final invoice was higher than our Firm Fixed quote.

NTE (Not To Exceed). With NTE, we will provide you with the maximum quote. Your final bill will not exceed that quote. It could even be less. There will be no additional billing that will drive the invoice over the NTE maximum price.

There could be some exceptions to the above pricing structures of which you will need to be aware. These include additional customer requests, optional Service Bulletins, missing or abused parts, and replacement of life-limited parts and engineering fees, if required.

Standard Pricing. Standard Pricing includes all labor required to perform the normal inspection or overhaul, and required parts. Any discrepancies found during the inspection that may require additional parts and labor, will be quoted over and above.

Each pricing structure has its advantages. We will work with you to identify which makes sense for you.

We realize that you have a lot of choices when it comes to servicing your landing gear. We know you want more than the minimum required.

  • You expect your downtime requirements to be respected
  • You require quality and experience
  • You demand a guarantee of a job well done
  • You want flexible pricing options to meet your budget,

Seems like an easy decision really. Duncan Aviation.

A Customer's Simple Act Speaks Louder Than Words of Praise

Posted by Diane Heiserman on Tue, Nov 22, 2016 @ 08:00 AM

Earlier this year at our Lincoln, Nebraska, facility, we re-installed three Honeywell TFE731-60 engines fresh from their initial 3,000 hour MPI on their Falcon 900EX, that delivered on-time from its major C-inspection. The aircraft’s first scheduled flight back in rotation was a trip to Europe.

With decades of honed turbine engine skills, we experience very few surprises when it comes to Honeywell TFE731 engines and MPIs. However flying that far right after a major inspection is significant.

According to Jeff Schwebke, Duncan Aviation Engine Project Manager, most operators fly locally around their home base after MPIs are performed to make sure there are no minor squawks to work through. “This simple action by a long-time Duncan Aviation customer says more about their trust in our work than glowing words of praise,” he says.

With an average of 192 MPIs a year for the last 15 years, experience has told us which parts should be ordered in advance, what components need a closer look, and how to put together a team of trained turbine engine technicians ready to get to work for every customer.

9-engine1 - Copy.jpg9-engine3 - Copy.jpg9-engine2 - Copy.jpg9-engine4 - Copy.jpg

With the triple MPIs completed, engines re-installed, and post-MPI performance runs, the customer’s aircraft departed with better engine performance than it had when it arrived.

Watch this time-lapse video and follow along as the engines make their way through the Duncan Aviation turbine engine shop for this triple MPI event.

35+ years

Duncan Aviation began servicing the first generation TFE731-2 engines in the early 1970s. In 1981, we received two major level authorizations to work on the Honeywell (then AiResearch) TPE331 and TFE731 engines. Over the years, as Honeywell added different TFE731 model engines, each was added to our capabilities.

Duncan Aviation's Honeywell Engine Authorizations, include: 

  • Heavy Authorization on TFE731-2,-3,-4,-5,-20,-40,-50,-60 engines
  • Minor Authorization on Honeywell AS907 (HTF 7000) Series 
  • Line Authorization on CFE738 Engines, GTCP36-100/150, RE100 series and RE220 series APUs.
Here’s to another 35 years of dedicated Honeywell service!

Everyday is Recycling Day at Duncan Aviation

Posted by Kaela Paseka on Tue, Nov 15, 2016 @ 08:00 AM

Duncan Aviation is not only the world leader in business aviation tip-to-tail support; it is also an industry leader in reducing the use of hazardous chemicals. In the past 10 years Duncan Aviation has reduced emissions of hazardous air pollutants by 50%.

At Duncan Aviation we have voluntarily chosen to apply the most stringent approach to controlling hazardous air emissions, applying maximum achievable control technology to our operations. And, our environmental staff is always looking for safer choices as they review chemical processes, protecting the environment and making Duncan Aviation a safer workplace.  

Duncan Aviation has a solid environmental compliance record. In June, our Lincoln facility received an unannounced EPA Hazardous Waste inspection. Employee training records, hazardous waste profiles, and storage areas were reviewed by the EPA. The company and its employees were credited for having no violations and the EPA inspector praised Duncan Aviation’s work in his review.

“We actively support our communities and respect the environment, and we encourage our team members to be mindful to minimize waste and recycle,” said Jeff Lake, the company’s Chief Operating Officer.

On November 2, 2016, we were chosen as the 2016 Lincoln, Nebraska, and Lancaster County Environmental Leadership Award recipient in the Business and Industry category, recognizing our efforts to improve the environment and protect public health.

Currently, Duncan Aviation is striving to have zero cardboard waste. Cardboard, it’s easy to identify and unlike plastic and glass, there is a steady demand to recycle it. It’s simple, recycle more and our trash service expenses will decrease, not to mention our future city taxes. Together we can postpone our communities needing to generate new landfills.

Here is a list of additional green initiatives Duncan Aviation is taking:

  • Foam Recycling since the beginning of 2015: 11,709.4 pounds (equaling 70 dumpsters) of foam from going to our local landfill
  • Adopt-a-Highway: twice a year in Lincoln and three times a year in Battle Creek, MI.
  • Winter Coat Drive for local homeless shelters
  • Annual Clothing Drives
  • Pallet Competition (companywide competition amongst employees)

Citation Sovereign: Want Winglets With That?

Posted by Diane Heiserman on Wed, Nov 02, 2016 @ 11:03 AM

Do you want to go further faster in your Citation Sovereign? We can help with that.

WingletPhoto.jpgFor much of 2016 we have been collaborating with Winglet Technology, LLC on an STC (Supplemental Type Certificate) to certify their Transitional Winglet design for the Citation Sovereign aircraft.

During this process, we installed the wing reinforcement, the winglet attach structure and the Transitional Winglets. Flight testing was completed in late August. The STC will be completed by the end of 2016, with FAA approval during the first quarter of 2017.

Any Sovereign operators, who desire greater operational flexibility and performance benefits, such as increased speed at altitude, increased range/payload, improved time-to-climb, and more, need to consider the Transitional Winglet upgrade.

Oh, and don’t forget that winglets just simply look cool. It is a ramp presence that is certain to turn heads. 

When it comes to winglets, we know what we’re doing. We are already authorized by Winglet Technology to install the Transitional Winglet STC on the Citation X.

Want to talk about it more?

Visit us in booth #3126 today at NBAA, or contact your Duncan Aviation Citation Service Sales Reps now.

Duncan Aviation and Rockwell Collins Show Off CJ3 Fusion Flight Deck Upgrade at NBAA

Posted by Lori Johnson on Tue, Nov 01, 2016 @ 08:47 AM

At last year’s NBAA Show, Duncan Aviation and Rockwell Collins announced that they would be collaborating on the CJ3 Fusion Flight Deck upgrade. At this year’s NBAA, the launch aircraft was flown to Orlando to display the future of CJ3 flight. Monday evening, the companies hosted a reception at the Orlando Executive Airport for CJ3 operators who have committed to or are considering the upgrade.

IMG_20161031_172437934_HDR.jpgThe new flight deck provides operators with an ADS-B mandate solution while enhancing their ownership and flying experience. The Pro Line Fusion upgrade replaces the factory-installed portrait displays with larger 14.1-inch landscape touchscreen primary flight displays. The new system includes intuitive, touch-interactive maps, and easy-to-use icons, giving the pilot the ability to control items on the screen through touch.  Also, it eliminates the need for Flight Management System (FMS) control display units originally installed in the pedestal.

According to the test pilots, who were available to answer questions Monday evening, the aircraft is a joy to fly. 

The Pro Line Fusion flight deck upgrade has been met with much enthusiasm from CJ3 operators and the early adopters who have committed to the technology and will soon be scheduling their upgrades.

“The collaboration, effort and professionalism shown between the Rockwell Collins and Duncan Aviation teams have been impressive and are the reasons the program has successfully reached this point,” says Steve Gade, Duncan Aviation’s Vice President of Business Development, Aircraft Sales and Marketing. “Certification will be complete in a few months and we are excited to begin transforming the CJ3 fleet with this exceptional avionics option.”

Did You Hear? Duncan Aviation Made a Heavy Announcement!

Posted by Sharon Klose on Mon, Oct 31, 2016 @ 02:00 PM

phone.jpgWithin 24 hours of Duncan Aviation’s Honeywell Heavy Maintenance Authorization announcement, my cell phone and email blew up with messages of congratulations from friends, colleagues, and industry contacts.

They were all happy for us!

“Great news!”


“Excellent news.”

Most were not surprised.

“Congratulations on the Heavy Maintenance! It has been a long time coming.”

“Congrats to Duncan Aviation getting the heavy ticket, I knew it was just a matter of time.”

“About time, Duncan Aviation.”

“Congratulations. This will be great for Duncan Aviation, Honeywell and the CUSTOMER!”

“This is a game-changer!”

“Wonderful news! When can I send my engines for a Core Zone Inspection? I want to be the first engine in the door!”

TFE-Shop.gifI’ve been in this industry for a LOT of years and talked to even more people. But it never gets old to hear appreciation from your peers. It’s having friends and business associates like these that continued to drive us towards expanding Duncan Aviation Turbine Engine Services knowing full well that if "we build it" they may come.

Speaking of building things, did you hear our other Minor announcement?

Our MRO in Lincoln, Nebraska, is now a Honeywell AS907 (HTF 7000) Series Minor Maintenance facility.
