Tribute To J. Robert Duncan, Part II

Posted by Kate Dolan on Thu, Apr 28, 2016 @ 10:37 AM

DonaldDuncan_RobertDuncan.jpgAs mentioned in Part I, Robert’s father, Donald Duncan, founded Duncan Aviation in 1956 and this year, Duncan Aviation celebrates 60 years. Now read the rest of the story of how Robert’s vision transitioned the small, family business from its modest beginnings into a company with a respected presence around the world.

Parts Consignment

Don Fiedler, now Manager of New Business Development for Components, joined the 10-year-old company in 1966 as the fourth member of the very new avionics team. The team repaired and installed avionics equipment on Bonanzas, Barons, and King Airs, and they also did some work on Harry’s helicopters.

As the industry started shifting from primarily piston engines to turbines, Robert saw the surplus parts for the older prop planes just sitting on shelves, and he surmised that there were probably FBOs around the country that had similar investments in unmoving parts. He envisioned a program where companies would send Duncan Aviation their surplus parts and, based on very new, barely known computer networking—a precursor of today’s Internet—Duncan Aviation would create an inventory of the parts and sell them on consignment.  This vision became AVPAC (Parts & Rotables today) in the early 1980s.

1985AVPAC.jpg“I've had the opportunity to work with all four generations. Donald in the early days, then Robert, and now Todd and his sons,” says Project Manager Howard Nitzel. “Robert always had good people to run the day-to-day operations for him. He would be looking at the future, always four or five years out, and willing to try new things. AVPAC is a classic example—a parts support services. It was kind of a pipe dream, and it really took off into a whole industry. Robert was a true visionary, made the company grow, and took care of everyone and their families. He’s a true businessman in every sense of the word.”

Don Fiedler explains that Robert’s vision was to establish a network, collect the parts, set fair prices, and ship them out to buyers the day they ordered.

“He wanted to make it easy to find parts and to get a fair price for them,” says Don. “And he wanted to make sure the inventory was meticulously maintained so we never claimed to have parts we didn’t. ‘First in, first out,’ was Robert’s rule.”

Robert  met with Bob McCammon (now manager of Aircraft Sales), Bob Tooker (Senior Sales Rep/Quality Control for Parts & Rotables Sales), Larry Stewart (former Senior Rotables Manager who retired in January after 43 years with Duncan Aviation), and Don Fiedler and explained his idea to get Duncan Aviation into the parts consignment business.

“It was a wonderful thing to work for that man,” says Don. “I’ve always looked up to Robert. I genuinely know him and really respect and like him. The word I most associate with Robert is ‘visionary.’ He surrounded himself with people who could take his ideas and run with them. And, to his credit, although the ideas were his, he always gave us free rein to make his dreams a reality.”

The Satellite Network

Once AVPAC was up and running, Robert again approached Don with an idea. This time, Robert told Rick Whitesell and Don of an experience he and his wife Karen had at a Lincoln’s Hovland-Swanson department store.

“Karen was trying on shoes, and as I waited, I talked to the manager of the shoe department,” says Robert.  “He told me he worked for a national shoe company. He said, ‘We specialize in shoes; we just lease this space.’ This got me thinking, ‘How could Duncan Aviation, with our expertise in avionics, expand that around the country?’”

Sat-History_03.jpgOne of Duncan Aviation’s greatest assets has always been its employees. Robert knew there were talented, experienced, knowledgeable technicians in Lincoln, hundreds if not thousands of miles away from where the avionics were that needed servicing.

“We joke that the avionics satellites are Robert’s five-minute idea that exploded,” says Don. “He said, ‘How ‘bout this idea? We lease space at established, respected FBOs around the country and put in two-man avionics shops. We keep it simple—do simple stuff in the field and continue to have the complex stuff sent to Lincoln. And we offer free loaners and free tech support.’ That was it!”

As a result of Robert’s “five-minute idea,” Duncan Aviation now has more than 20 avionics satellite shops located at busy airports around the country. Not only do our customers drop into these facilities for quick repairs, but also they can schedule complex installations, including upgrades to avionics that satisfy the NextGen mandates.

Robert credits Don for the success of the program. “It was my concept, but Don ran with it, and now Matt is managing all of them,” says Robert.

Matt is Matt Nelson, Manager of Satellite Operations. He started at Duncan Aviation in 1987 when he was 18 years old, and it was his first full-time job.

“It was summertime, and Todd Duncan and I were in the warehouse washing cars and airplanes,” laughs Matt. “We were about the same age, and we worked hard.”

As someone who has worked at Duncan Aviation for 29 years, Matt is a member of an exclusive club called Silver Wings.

Silver Wings

Silver Wings is a club that Robert created to celebrate employees who have worked at Duncan Aviation for 25 years or more. Because silver commemorates a 25th anniversary, the group that worked with Robert to establish the club chose Silver Wings as its name.

“It’s a way to recognize all of the many contributions our steadfast, loyal, dedicated employees have made in their tenure here. Many of them have been here far longer than 25 years, too, including Don Fiedler. This year, he’ll celebrate his 50th year with the company,” says Robert. “The Silver Wings employees, about 300 of them now, are the core of what Duncan Aviation is about, and they’re the reason so many of our customers can call Duncan Aviation and talk to the same person they’ve dealt with for 25 years or more. It means so much in our industry, and it means so much to us as a company, too.”

SilverWings2014_2.gifThose employees say the same thing about Robert Duncan and Duncan Aviation

“This company has been my life, mostly because of how the Duncan family has always cared for their employees,” says Don. “It’s a company built on integrity, and I’ve always felt privileged to be a part of something so special. It was such an adventure to get hired on at such a young, exciting place, and I’ve been here to see it grow and become the respected company it is today.”

Todd Duncan, too, is a member of the Silver Wings club, as he has been working at Duncan Aviation for 28 years.

Robert’s Son, Todd Duncan

Robert_Todd.jpgTodd has been Chairman of Duncan Aviation since 2007, and he’s seen the company ride the waves, the highs and lows, of the business aviation industry.

“One thing I’ve always admired my Dad for is what he brought to the business every single day, regardless of what we were facing, and that’s his optimistic spirit. He’s always able to look to and find brighter days,” says Todd. “He’s a tremendously forward-looking man, and he’s always so positive. He cares deeply about our employees and our customers. He’s the kind of man who inspires others to do their best, too.”

Todd agrees with what Robert calls the immeasurable value of the employees at Duncan Aviation. Father and son are keenly aware of the network of support they have created and developed at Duncan Aviation.

13100833_10153785619453999_2127267970112683311_n.pngYesterday, at the annual AEA convention in Orlando, Florida, Robert was given a life-time achievement award, recognizing his contributions to the aviation industry and acknowledging everything he’s done at Duncan Aviation in the last 60 years.

 “I couldn’t have done it alone. Everybody out there is doing the work every day—turning the wrenches, fixing the avionics, selling something, or providing support in accounting,” says Robert. “It takes everyone to make this company succeed.”

Duncan Aviation's R&D Has Had a Ripple Effect Throughout the Industry

Posted by Diane Heiserman on Tue, Dec 22, 2015 @ 04:24 PM

With only $30,000 and 90 days, Ed Gilmore, then Duncan Aviation Avionics Bench Tech was challenged to design and develop a working prototype to replace the Collins 980L autopilot test set.

He did it. That was 1981 and only the beginning.

1994Don-Reeves_RichTeel_Ed-Gilmore.gifOriginal R&D Team circa 1984 

With the help of a local community college instructor and another former Duncan Aviation team member, Ed designed and built the DATE 1 (Duncan Aviation Test Equipment).

It was probably the first-ever computer controlled test set in General Aviation. It used an Apple II-E computer with whopping 64K of memory. It was functional and remained in service for many years.

This test set laid the innovative foundation for what would eventually become Duncan Aviation’s Research and Development (R&D) team. Established in 1984, the R&D department was initially created to support Duncan Aviation’s Avionics Satellite network.

The initial Avionics Satellite shops opened up across the country with the first generation DA test equipment that consisted of large panels taking up a lot of space. In order to grow, the equipment needed to shrink. R&D’s task was to develop test equipment that integrated the current equipment into smaller boxes with increased testing capabilities. But another important requirement was for the equipment to look high-tech and “cool”.

softset.gif
Photo of an original Softset developed by the Duncan Aviation R&D department. 

By 1985 the team began the development of equipment that used software rather than hardware called SoftSet. SoftSet was able to test 80 percent of the avionics units that arrived at Duncan Aviation for repair or overhaul.

By 1990 DATE 1 was upgraded to DATE 1A, converted to run on a Macintosh computer and included the addition of Artificial Intelligence (AI). AI assisted in troubleshooting units and offered solutions based on repair history. The equipment got smarter with each test and became more accurate with repair recommendations.

By the mid-90s, both SoftSet and DATE 1 were advanced further with the ability to handle an advanced number of capabilities with a significantly smaller footprint…and they looked “cool”.

DATE 1B became fully automated in 1996 significantly reducing test times. For example the 4.5 hour test of a 562A-5M5 Collins A/P was reduced to 50 minutes and the eigh hour test of the CA-200 Sperry A/P was able to produce results in only three hours. This freed the technicians to do other things and get the units returned to customers quicker.

For the last 30 years, Duncan Aviation’s R&D has provided far more than just support for the Avionics Satellites. The lion share of their projects are smaller dedicated circuits, mockups, test boxes, modules, and mechanical jigs for the rest of the company.

These projects have helped facilitate Duncan Aviation to hold and grow in the avionics repair market, by providing quality test equipment, support documentation and assistance with certification.

Chris Hogg, R&D Tech, says that this innovation is a partnership between R&D and the technician on the floor. “When the technician sees an opportunity to make how they do their job better, faster or more efficient, they get us involved. We work together to provide services that bring the idea to reality, which is very gratifying. We have had more than a thousand such projects, each a story unto itself.

Other R&D Designed Projects

The Falcon Flight Control Force Tool measures the force required by the pilot to move the control wheel and rudder pedals on Falcon 2000, 900 and 50 series aircraft. It has been recently granted ‘tool equivalency’ status by the FAA after an extensive comparison to the original factory tool.

The R&D also crafted Tail Stand Alarms that notify the mechanics prior to the aircraft making contact with the tail stands.

R&D utilizes 3D printing technology to reduce fabrication time and project costs. It has also been used to provide mockups of in-house developed antenna mounts for aircraft.

DATE 1C upgrade is in development and will replace the current Mac computers used in the Duncan Automated autopilot/flight director Test Equipment with PCs.


The development of this software and equipment is one of the many examples demonstrating how Duncan Aviation employees strive to stay at the front of business aviation, providing innovative, responsive and revolutionary customer service.

Innovative technology has a ripple effect that doesn’t end when a project is over. Today’s fresh new ideas become the foundation and infrastructure for tomorrow’s next big thing. This natural evolution allows those who are willing, the ability to think creatively and find the next step.

Duncan Aviation and Aviation Alphabet Associations: AEA

Posted by Diane Heiserman on Thu, Aug 13, 2015 @ 09:38 AM

Ron-Hall-phone-call

"As we grow, our issues are not just our issues, but issues we share with others. By becoming active members of our industry associations, we have an opportunity to be side-by-side with our industry peers, competitors and customers, to learn their concerns and needs so that we can come alongside them and help them exactly when they need us. It is only through the conversations and relationships we gain by being active in these associations that we move our industry forward."  

Todd Duncan, Duncan Aviation chairman

Duncan Aviation has been a member of the Aviation Electronics Association (AEA) since 1970 after Ron Hall (above), a retired Duncan Aviation avionics sales rep, attended his first AEA convention in Kansas City.

According to Ron, those early conventions were small, with only about 150 people and booths consisting of little more than cardboard structures with a table.

In those early days, AEA drew companies together to discuss their frustrations and share their ideas and successes with the latest technical information. Even though many were competitors, they shared anyway in order to make the industry better. Ron says it was this collaboration that helped Duncan Aviation to grow from a small radio and instrument shop into an experienced facility with technicians specializing in the maintenance, repair and installation of the latest in avionics technology.

Duncan Aviation Avionics Sales Rep Ron Hal was an AEA board member for 20 years.

Shortly after his first convention, Ron joined the AEA Board of Directors and stayed for 20 years. During those two decades, Duncan Aviation hosted three regional meetings in Lincoln, Nebraska.

In 1985, Ron was named the AEA Member of the Year. And because of his dedication and continued involvement in AEA during his entire career, he received the AEA Lifetime Achievement Award in 2011—the highest honor bestowed on an AEA member.Robert-quote

Duncan Aviation's AEA involvement and influence didn't end with Ron's retirement. Gary Harpster, avionics installation sales rep, stepped up and actively participated at several regional and national AEA events. As a well-known expert in the industry on NextGen technology, he has presented educational sessions to operators around the world.

Gary was an active board member, serving as vice chairman and chairman of the board for several years. He also served on the AEA Trusteeship Committee and was named 2008 AEA Member of the Year.

Another chapter in Duncan Aviation's AEA history unfolded in 2014, when Mike Minchow, manager of completions and avionics sales, was among the newly elected directors selected by the members of AEA.

Today, AEA boasts nearly 1,300 member companies in 43 countries.

In The Trenches

Business aviation association governing boards work to benefit our industry as a whole, bringing about long-term changes and future growth. But oftentimes, it’s in the trenches of the subcommittees and regional events where the day-to-day issues that impact business aviation are addressed. Many of Duncan Aviation’s tech reps, department leaders, regional managers and sales representatives meet many times a year in these industry subcommittees.

An Aircraft Gyro Reminder That Will Save You Thousands of Dollars

Posted by Duncan Download Blog on Wed, Apr 22, 2015 @ 10:25 AM

handlelikeeggsSubmitted by Curt Campbell, avionics tech rep

There have been many articles and videos in the Duncan Intelligence over the years, written and produced by tech reps and technicians at Duncan Aviation about the proper care and maintenance of an aircraft gyro. 

However, it wasn't long ago that I got a call from an operator who was having precession errors and failures to erect on his gyro. It didn't take long for me to figure out that the cause of his issue was the result of the gyro not being allowed enough time (20 minutes) to spool-down before the aircraft was moved.

He stated his crew wasn't aware of this required spool-down time. This oversight unfortunately required a complete overhaul of the gyro, costing several thousand dollars.


Time for another reminder..

Duncan Aviation's AEA Highlights

Posted by Diane Heiserman on Wed, Apr 15, 2015 @ 01:34 PM

booth-from-aboveThe Aircraft Electronics Association (AEA) declared the 58th annual AEA International Convention & Trade Show a success with record 1,897 attendees. According to reports about the traffic in Duncan Aviation’s booth from our team members who were at the show, most of the attendees must have stopped by.

By and large, the best part of AEA was the face-to-face connections made with customers and vendors, both old and new.

Here are some photos and personal highlights from several of Duncan Aviation team members who were in Dallas, Texas, at AEA 2015.

Larry Troyer, avionics instruments tech rep

The biggest highlight for me was meeting face-to-face with some customers I have worked with on the phone. It was good to establish those relationships and renew old ones.

Scott McKenzie, avionics instrument tech rep

My highlight for this conference would be the same as all of the others that I have attended in the past. That is the opportunity to meet the customer's face-to-face that I communicate with on a regular basis, either on the phone or email. The personal interaction seems to go a long way in helping build not only a good working relationship, but in many cases true friendships as well.

I found a lot of good information about upcoming requirements, such as ADS-B available.  

Vince Cruickshank, rotable sales manager

I enjoyed being able to connect with so many long-time and new customer vendors in one venue. We spoke about the new growth between our companies and how we can better serve each other’s needs.

Mike Morgan, avionics sales rep

I always enjoy being able to connect with our vendors and build on those relationships, as well as, connect with potential new vendors and new products coming to market. Also during the convention this year I was able to get a better perspective of the state of the business aviation industry.

Michael Meyer, avionics team leader

There were more learning opportunities than I could possibly take advantage of. I was happy with the educational sessions I was able to attend. The main themes were ADS-B and connectivity. And the message I got is that the ADS-B mandate will not change and we have a lot of work to do by the end of 2019.

While walking the convention floor, I was able to see some of the new equipment we will be using in the near future.

Two Most Common Failures of the APS-80 Autopilot System

Posted by Duncan Download Blog on Tue, Jul 15, 2014 @ 09:00 AM

APC---80

 

Larry  Troyer, Duncan Aviation Avionics Instrument Tech Rep, troublshoots the two most common causes of APS-80 Autopilot System failure. 

The autopilot / flight director system is a complicated system that is common in aircraft from light twins to corporate jets. 

  1. FGC-80- (Flight Director)
  2. APC-80
  3. APA-80

The FGC-80- (Flight Director) processes all lateral/vertical signal inputs depending on the selected mode. It controls the position of the command bars in the Flight Directory Indicator and sends commands to the APC-80. APC-80 receives and processes commands from the Flight Director computer and passes them on to the APA-80, which drives the individual servo motors to control aircraft flight.

Two Most Common Failures

1.   Autopilot intermittently disengages during flight

Most likely cause is the APC or APA. These computers have multiple internal dc power supplies that tend to get out of tolerance or fail completely. They can be temperature sensitive (hot or cold) failing at one specific temperature.

Troubleshooting:

  • If you are able to duplicate the discrepancy on the ground, it is possible to isolate the faulty computer by heating or cooling each box individually.
  • Engage the autopilot on the ground and manually override the controls in pitch or roll. If the autopilot disconnects, the most likely cause is in the APA due to faulty torque monitors.

2.   Autopilot will not engage

Troubleshooting:

When the autopilot won't engage, the APA and APC is still most likely the cause. However because of the extensive internal computer monitoring, there are many other things that could be contributing to the failure. When activating the lever to engage the autopilot, the system automatically initiates a self-test routine. During this self-test a dc voltage is sent to the two NAC-80 accelerometers that in turn generate a fixed signal back to the APA. A correct signal is required to successfully pass the self-test. The NAC-80s also put out a valid flag which is monitored in the APP-80 control head as a condition for engagement.

Other conditions required before the autopilot will engage:

  • Valid vertical gyro
  • Valid from the yaw damper computer
  • Correct part number status on both computers (APA & APC)
  • Continuity thru the yoke disconnect switch

If you have access to a breakout box or logic monitor it helps to isolate the problem down to a box or aircraft problem. Other wise the majority of the times engage problems are caused by either the APC-80 or the APA-80 computers.

Troubleshooting Aircraft Radar Spoking

Posted by Duncan Download Blog on Thu, Mar 20, 2014 @ 01:00 PM

Contributed by Dan Magnus, avionics instruments tech rep

Radar Spoking

Example indications of spoking.

Spoking is a general term used when a radar system fails. You can determine which part of the system is causing the problem based on what appears on the radar display.

The most common type of spoking is caused by the magnetron or local oscillator. This occurs when they lose lock and do not track with each other. This will typically appear on the radar display as a pie shaped patch and will only be present if there is weather to be shown. This would be a receiver transmitter problem.

Another type of spoking comes from the antenna and is caused by noise from the sweep resolver. This will normally show up on the radar display as a very thin line that will start at the apex of the screen and continue to the edges, no matter which range you are on. This will almost always appear in the same spot on the screen.

Intermittent connections on the antenna can also cause the antenna to pitch up or down causing spikes or humps within the return. This is a common problem for the Primus series of antennas.

Duncan Aviation Tech Rep Recommendations: Aircraft Radar Operation

Posted by Diane Heiserman on Fri, Mar 07, 2014 @ 02:45 PM

Duncan Aviation

Duncan Aviation radar technicians use the term “Radar Season” to describe the time of year when high winds and instability in the atmosphere whip up severe thunderstorms capable of producing tornadoes. At the beginning of Radar Season, when pilots rely heavily on their radar units to perform perfectly, is when many unexpected squawks may be encountered. 

Below are four Duncan Intelligence articles written by Duncan Aviation's Avionics Tech Reps with tips and recommendations about basic radar operation.
