Worldwide Business Aircraft Operators Tell It Like It Is

Posted by Diane Heiserman on Tue, May 27, 2014 @ 12:59 PM

We have customers who fly from Europe to have maintenance completed at one of Duncan Aviation's United States locations. The fact that they're willing to make that trip tells us we're doing something right; their words tell us exactly what we're doing that makes the flight worth it.

Duncan Aviation Updates its Popular “Straight Talk About FANS” Ebook

Posted by Duncan Download Blog on Wed, Mar 12, 2014 @ 10:43 AM

Straight Talk About FANS

Duncan Aviation recently released an update to its “Straight Talk About FANS” ebook, which gives operators a closer look at the Future Air Navigation Systems involved with the FAA’s NextGen initiative.

Duncan Aviation’s team of experts compiled information to explain FANS 1/A, including what equipment is needed and how it functions, the benefits of the enhanced communications systems and the applicable regulations and certification in an easy-to-read ebook.

Justin Vena, Duncan Aviation Avionics Installations Sales Rep in Battle Creek and others at Duncan Aviation know there are many operators wondering what each of the FAA’s NextGen systems are and how they are used, the costs of implementation and whether there is a datalink system for their aircraft.

“Although there are no easy answers in the retrofit market, our Straight Talk About FANS is meant to help clarify the FANS protocol and how the mandates affect communication systems in various aircraft,” Vena says.

Vena explains that there is no one datalink system that will fit every aircraft, and often it takes a variety of avionics equipment to comply with the new guidelines and mandates. “Our, avionics experts have done the research and can assist customers with any questions regarding FANS,” he says.

To download a copy of Straight Talk About FANS, visit

In addition to this publication about FANS 1/A, Duncan Aviation avionics experts have developed Straight Talk booklets for NextGen and other systems including Reduced Vertical Separation Minimums (RVSM) and Automatic Dependent Surveillance-Broadcast (ADS-B).

For more information, stop by booth #604 this week at the Aircraft Electronics Association (AEA) 57th Annual International Convention and Trade Show in Nashville, Tennessee.

Navigating A Business Aircraft Import While Overseas

Posted by Diane Heiserman on Fri, Dec 20, 2013 @ 10:43 AM

Dan Moody

No two business aircraft import and exports are exactly alike. That's when decades of experience come in handy while navigating the process. That’s where Dan Moody steps in.

Dan Moody, MRA project coordinator, spent four extra days overseas working diligently to complete the U.S. import and inspection of a Swiss aircraft as well as issue a Standard Airworthiness Certificate. 

Because the aircraft was registered in Switzerland and was required to be de-registered there, Dan had to inspect the Falcon 7X in country, so he flew overseas to Geneva to serve as the customer’s consultant.

After the aircraft was de-registered and placed on U.S. Registry, Dan needed to obtain a special flight authorization to get the aircraft within the United States to complete the import process.

“I contacted the nearest FAA office in Frankfurt, hoping to simply send the necessary paperwork their way, and they informed me I needed to hire a Designated Airworthiness Representative (DAR) to come inspect the Falcon and approve the authorization,” says Dan.

Facing an unknown delay based on the DAR’s availability, Dan approached the customer with two options: wait for the DAR to arrive and hopefully approve the flight authorization or Dan could stay a few extra days and complete the entire import process, negating the need for the authorization.

“Experience is the only thing that can prepare you for something like this,” says Dan.

Dan was able to complete the import on foreign soil and issue the Standard Airworthiness Certificate during the extra days he was in Switzerland.

“The customer was overjoyed. In fact, He asked Duncan Aviation to paint the aircraft at its Battle Creek, Michigan, location,” says Dan.

Crossing Borders: Importing and Exporting Aircraft

During the last several years, the business aircraft industry has seen increased numbers of new and preowned business aircraft being sold overseas. As a result, aircraft buyers, sellers and service facilities are increasingly involved in cross-border transactions. Read more about how Duncan Aviation navigates this complicated process in the 2013 Fall Issue of the Duncan Debrief.

Falcon 900B: On a Clear Path to Meet Upcoming Mandates

Posted by Diane Heiserman on Thu, Oct 17, 2013 @ 07:00 AM

Submitted by Gary Harpster, senior avionics installation sales rep

Right now there are approximately 20 to 25 Falcon 900Bs on the market available for sale. In talking with these owners, I’ve learned the majority of these aircraft were placed up for sale over the concern there was no upgrade path to meet the upcoming mandates and essentially rendering the aircraft as domestic use only.

I totally get it. Who wants an aircraft capable of Mach .84 - .87 that can travel 4,600 miles and only be able to fly it in the 48 contiguous states? 

Universal EFI-890

On the Falcon 900B, the engines, airframe and accessories are still highly supported. Therefore, the weak link in this analysis becomes the avionics. However I am hear to tell you, when it comes to meeting the needs of the mandates for both the U.S and abroad, there is a clear path.

With the installation of the Universal EFI-890 solution, a Falcon 900B gains many of the same capabilities of new production aircraft and in some cases, even more. Charts, weather, synthetic vision, electronic engine gauges, camera input, new LED displays, WAAS FMS with LPV and the necessary accuracy to fly in Minimum Navigation Performance Specifications (MNPS) airspace.

Want to fly to Europe and fly in the most favorable tracks doing so? This is the solution.

Want to jump up into the airspace over Europe on the bosses schedule and not when air traffic allows you to depart? This is your solution.

Add winglets, new custom interior and paint, a state of the art entertainment system and you have yourself one heck of an aircraft that will meet the needs of the future for the next 10 years.

Or as an option you could buy a used aircraft with these capabilities for more than seven and a half times what this upgrade would cost you.  Keeping in mind that if you wanted the custom paint, interior and entertainment – that would all be additional.

On Display at NBAA

Why just read about it when you can come see it. During NBAA at static display #140 on the Henderson Executive Airport in Las Vegas, I personally invite you to walk through and see a Falcon 900B with the first EFI-890R cockpit retrofit upgrade. I will be on-hand to answer any of your questions, as well as representatives from Universal Avionics.

Also featured on this aircraft is a newly designed interior, new paint and new cabin/management/entertainment system; all completed by Duncan Aviation. 

How weak is that link now?

Duncan Aviation at EBACE

Duncan Aviation representatives stayed busy during EBACE 2013.


A week ago the 2013 European Business Aviation Convention and Exhibition (EBACE) in Geneva, Switzerland, got underway with 460 exhibitors lining the halls of the Palexpo ready to meet and greet all the delegates attending the show. Duncan Aviation, in Stand #327, was among them.

According to Arjen Groeneveld, Duncan Aviation’s Regional Manager for Europe and Russia, because EBACE is the biggest show in Europe, it is very important that Duncan Aviation be at the show and have representatives on-site available to talk with customers. “Every year Duncan Aviation’s name recognition in the European business aviation market is more well-known than the year before. This is because, as a company, Duncan Aviation works hard to make the connections, offer the best value in aircraft maintenance and then follows through with the highest quality of work promised.”

Arjen goes on to say, “because the European business aviation market is so small, everyone knows and talks to others and passes along their opinions and critiques of who and where they did business, both good and bad.” Duncan Aviation has a good reputation in Europe and many customers have let us know how much they enjoy working with us.

Arjen had specific goals during the show to establish and strengthen relationships with European customers and business aircraft management companies by introducing them to Duncan Aviation’s representatives in attendance from from Battle Creek, Michigan, and Lincoln, Nebraska.

Interior Craftsmanship in Action

During EBACE, Duncan Aviation was pleased to provide attendees with the opportunity to see some of the company’s interior craftsmanship and capabilities as Bombardier Aerospace unwrapped their Challenger 350, an upgraded Challenger 300 with a new wing, more powerful engines, larger windows and redesigned interior. The Challenger 350 aircraft mockup was completed by Duncan Aviation and was on display in Bombardier’s stand.

“Collaborating with Bombardier for the mockup display of its Challenger 350 aircraft was an honor,” says Mark Cote, Duncan Aviation’s Vice President of Completions and Modifications. “The aircraft promises to be an astounding addition to the Bombardier business aircraft line-up and we are pleased that we could help them share their vision with this beautifully completed interior mockup.”

Customer Letters: International Pre-Purchase Evaluation Done Right!

Posted by Diane Heiserman on Mon, Dec 31, 2012 @ 07:42 AM

International Pre-Purchase Evaluation

When purchasing a business aircraft with a foreign registration, select a pre-purchase facility that knows what they are doing.

Our customers have come to expect a higher standard of service from us when it comes to the maintenance and care of their business aircraft. And although we can say that we do it better than any other major repair and overhaul service (MRO) provider in business aviation, our customers say it best. Below is a customer letter written and sent to Monte Reeves, Duncan Aviation’s Manager of Customer Service located in Lincoln, Nebraska, explaining his recent international pre-purchase experience with Duncan Aviation. All customer information has been removed at their request.


I wanted to write you to express my thanks, as well as appreciation, for the recent work Duncan Aviation and your team provided on the pre-purchase and paint of our Falcon 2000 EASy. In order to give you the proper perspective of our experience, here is a little background.

Previous Pre-Purchase Experience

Sixteen months ago, we purchased a German-based Citation Sovereign. Although we have purchased a number of business aircraft over the past 20 years, this was our first experience acquiring one registered in a foreign country. The experience was difficult, tedious and took much longer than we had expected. The process of de-registration and re-registration was cumbersome, as was the pre-purchase inspection that was accomplished in Germany, at the seller’s insistence.

Shortly after taking ownership, we made the decision to have extensive airframe and paint work accomplished and took the Sovereign to one of your competitors where we were told the paint work would take five to six weeks and in actuality took over seven. In the end, the quality of the work and new paint were fine, but the experience was much longer (over six months) and more difficult than we anticipated.

Our Duncan Aviation Experience

When we began the process of acquiring a Falcon 2000, we were very leery about purchasing another foreign-registered aircraft, due to the previous bad experience. However, we found the right aircraft for us based in Belgium and decided to proceed with the purchase. Our only stipulation was to accomplish the pre-purchase inspection in the United States. The seller agreed.

After consulting with several people in the industry, we contacted Duncan Aviation and brought the aircraft to Lincoln, NE. Even though we have been in the aviation business for some time, this would be our first experience with Duncan.

We, like every other operator purchasing a new aircraft, wanted to get it in right away. Our Director of Maintenance talked with Tim Klenke, Falcon Airframe Service Sales Rep, and explained our needs, including bringing the aircraft into the country under foreign registration, performing the pre-purchase inspection, de-registering, re-registering, etc. With this instruction, Tim coordinated everything with your production teams and Duncan Aviation was able to accommodate our tight schedule. I was able to talk with Dan Moody, MRA Project Coordinator, personally and got a good comfort level of how the registration process would happen.

When we arrived, we were met and greeted at our aircraft by our Project Manager Steve Ballard. The next morning we had a briefing with a representative from every department that would be involved in our project. I was impressed that there was not only airframe and engine representatives present, but also interior, documentation and engineering. We were able to review each of the items on the pre-purchase, as well as extra items that we wanted done at our request outside the scope of the pre -purchase. Each one in that meeting was not only knowledgeable, but professional and friendly.

As we took a tour of Duncan’s Lincoln facility, the first thing that surprised me was how busy everyone was. Over the next several weeks, we not only saw a great work ethic, but your people were genuinely friendly and extremely knowledgeable. If we had questions or concerns about the project or our aircraft, they responded quickly and followed up when necessary.

Half-way through the pre-purchase, we decided to add a new paint job to the workscope. Due to scheduling constraints of your very busy paint shop and registration issues, there was some doubt that our request could be accommodated. However, Steve, together with many production people, came together and worked out a plan that included a new paint and kept the project very close to the original schedule.

Exceeding Expectations

The paint process was split into two phases. Dan Moody assured me the new plan would have no impact on his process and the interior shop assured us they could get their work done around the schedule changes. At this point, I should also mention when I first talked to the people in Duncan's paint and design department, I was told the aircraft paint project would be completed in three weeks. Now if I hadn’t already known of Duncan Aviation's reputation for quality aircraft paint work, I would have been very suspicious since we just watched our Sovereign take seven weeks somewhere else.  

The end of the story is that our Falcon 2000 was delivered four days ahead of schedule. The work quality was excellent, including the paint and interior work. And the registration process was so smooth, it was almost a non-issue. All of the Duncan Aviation people on our project worked hard, but not at the expense of the customer relationship. We were always treated with respect and felt they understood how important our aircraft was to us, even though they must deal with the same relationship with every customer. They really did want to get it right.

As our Project Manager, Steve was on top of everything all the way. He and some of the department leaders handled a few difficult situations that arose early on in the project between the seller and buyer with courtesy, professionalism and knowledge; defusing some potentially rough spots in the process. On the occasions when we weren’t on-site at Duncan Aviation, kept us connected and made things understandable and easy.

Whatever You are Doing, Keep Doing It

I could try and list as many people by name as I could to say Thank You, but I know I would be leaving too many out. Whatever you are doing, keep doing it. Please make sure that everyone from Line Service to the Front Desk; Paint and Design  to Engineering, including Interior, Airframe, Engine, Detailing and any other department that touched our aircraft while at Duncan Aviation, knows what a great job they did and what an excellent experience we had.

You Get What You Pay For

Initially, I was concerned that your labor rate was high. However, it soon became obvious that for every hour of labor I bought, I actually got an hours worth of labor. The end cost was less than when you pay a lower hourly rate and only get part of an hour's work. Imagine that!

Pre-Purchase Services For Buyers & Sellers

Duncan Aviation's only focus during a pre-buy evaluation is to provide the most accurate assessment on the condition of an aircraft to the buyer and seller. Our comprehensive services allow us to correct most discrepancy repairs in-house.

New avionics systems, interiors and industry-leading paint can be updated during the process, providing buyers with a high-quality product with as little downtime as possible.

Business Aircraft Acquisition Services

Locating and purchasing a pre-owned business aircraft is incredibly complex and risky. The stakes are huge. A small oversight can cost hundreds of thousands of dollars. But a little insight can gain an equally large advantage. Talk to an experienced business aircraft acquisitions expert, to located the business aircraft that matches your needs. Duncan Aviation is the largest, family-owned maintenance, repair and overhaul (MRO) facility in the world providing complete acquisition sales and support services for business aircraft.

Mandate Speculations Surround TCAS 7.1 Upgrade

Posted by Diane Heiserman on Tue, Jul 17, 2012 @ 01:38 PM

Contributed by Matt Nelson, Duncan Avionics Satellite Operations Manager

The recent Traffic Collision Avoidance System (TCAS) 7.1 upgrade offers two major safety enhancements, which are significant enough to warrant mandates by more than one international organization. Additionally, an FAA statement has stirred speculation for the possibility of a future U.S. mandate.

As most of you surely know, TCAS involves communication between all aircraft equipped with an appropriate transponder. Each TCAS-equipped aircraft interrogates all other aircraft in a determined range about their position (via the 1030 MHz radio frequency), and all other aircraft reply to those interrogations (via 1090 MHz).

What you may not know is how the TCAS 7.1 upgrade affects aural warnings and TCAS reversals, and other minor enhancements that have caught the attention of international regulatory agencies.

Safety Enhancements

TCAS 7.1 is being offered as an upgrade by all of the major TCAS manufacturers and makes two important safety enhancements.

  1. Aural Warning Change – The current TCAS II aural warning will be changed from “Adjust Vertical Speed, Adjust” to “Level Off, Level Off”.
  2. TCAS Reversals – TCAS 7.1 corrects missed and late TCAS reversals. TCAS reversals were introduced in TCAS 7.0 to adapt to changing situations where the original sense had clearly become the wrong thing to do, in particular when a pilot decides not to follow the Resolution Advisory (RA), or is instructed by Air Traffic Control (ATC) to perform a particular maneuver. The solution in Change 7.1 introduces improvements to the current reversal logic that addresses the late issuance of reversal RAs and potential failures to initiate reversal RAs.

Other Minor Enhancements

  1. Corrects issue when descending through 1000 ft. AGL.
  2. Modifies the “Datalink Capability Report” (Status report sent by the TCAS processor to the Mode S transponder) to tell the systems that the TCAS processor is hybrid-surveillance-capable.
  3. Allows for the transmission of the TCAS processor part number and software level.
  4. Corrects TCAS multi-aircraft logic issues, which reduces the risk of “close-encounters” of multiple aircraft in RVSM airspace.

International Mandates

These enhancements are significant enough to warrant mandates by both the International Civil Aviation Organization (ICAO) and the European Aviation Safety Agency (EASA). ICAO has mandated TCAS 7.1 by January 1, 2014 for forward fit aircraft and January 1, 2017 for retrofit aircraft. By comparison, EASA required all forward fit aircraft to be mandated by March 1, 2012, with retrofit aircraft to follow by December 1, 2015.

The U.S. FAA is reportedly a “strong supporter” of TCAS 7.1 and has issued the following statement:

“The latest version of software for TCAS II is version 7.1. To ensure compatibility with international standards, the FAA encourages the installation of this software as soon as practical.”

This statement has stirred thoughts among the avionics manufacturing community that TCAS 7.1 may be mandated in the US.

The certification path for TCAS 7.1-modified units will be accomplished through a Supplemental Type Certificate (STC), Type Certificate (TC) or in some cases a Major Repair Alteration (MRA) project with a re-write of the Airplane Flight Manual Supplement (AFMS). To determine the certification path for your aircraft, please have a copy of your AFMS handy and call an avionics professional within the Duncan Avionics satellite network.

Straight Talk About ADS-B also includes a section on TCAS II Version 7.1, with discussion on how the two systems are linked.

FANS/ Link 2000+: What You Need to Know About Flying in EASA Airspace

Posted by Diane Heiserman on Thu, May 10, 2012 @ 06:00 AM

Contributed by Justin Vena, Avionics Installation Sales Rep

FMS 6100

Bottom Line: If you routinely fly in the world's oceanic routes, you want to be FANS and Link 2000+ compliant.

The Three major OEMS for business aircraft in operation within EASA airspace are exempt from the Link 2000+ mandate that takes affect after 2015 under Article 14. Basically, if you operate an out-of-production business aircraft in EASA airspace only and do not plan on traveling internationally, you are exempt from the Link 2000+ mandate. You will need to file an exemption request with EASA and obtain approval under Article 14. There are two articles of exemption, Article 1 aircraft are permanent exemptions and Article 2 are temporary exemptions.

Does my Business Aircraft have to comply with the Link 2000+ mandate to fly in EASA airspace after 2015?

The short answer is yes and no.

No. All non-production business aircraft in operation within EASA airspace are exempt from the Link 2000+ mandate that takes affect after 2015. Basically, if you operate an out-of-production business aircraft in EASA airspace only and do not plan on traveling internationally, you are exempt from the Link 2000+ mandate.

Yes. All current production model aircraft will have to comply with the Link 2000+ mandate after 2015.

Does my aircraft have to comply with the FANS mandate to fly in the North Atlantic Tracks after 2015?

Yes. The North Atlantic Tracks (NATs) are the fastest and most efficient routes between North America and EASA. After 2015, all aircraft flying the NAT must be FANS compliant.

Take note, the two center tracks of NAT will be closing to non-FANS compliant traffic by 2013.

International Travel Options

If you don’t want to pay the expense required to become FANS compliant, you are not totally without options. As stated above, by the end of 2013, ONLY the center two NAT tracks will become unavailable non-FANS aircraft. There are other routes available between North America and Europe. However, these routes are longer and have less than ideal conditions.

If you consistently fly these routes rather than the NAT, you will incur higher operating and maintenance costs associated with the added flight hours. Many aircraft will also require an aditional fuel stop for Atlantic crossings.

Best Equipped = Best Served

There are many oceanic routes around the world that, at the present time, do not require aircraft to be FANS compliant. However, they are beginning to adopt the “Best Equipped, Best Serviced” policy. It is not uncommon to hear of an aircraft having to sit on the runway waiting for clearance to take-off as other better-equipped aircraft are allowed to leave before them.

Duncan Aviation's team of avionic experts have compiled information to explain FANS 1/A, equipment, operational facts, benefits of the systems and regulation and certification in the easy-to-read ebook: Straight Talk About FANS. Download your copy here.

Justin will be attending European Business Aviation Convention and Exhibition (EBACE) in Geneva, Switzerland, from May 14 – 16. If you have any questions or want to talk about NextGen initiatives, schedule an appointment or stop by stand #456.
