Duncan Aviation Tech Rep Recommendations: Aircraft Radar Operation

  
  
  
  

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.

(Video)DGS-65 Directional Gyro: Importance of the Encoder Flex Card

  
  
  
  

The DGS 65 Gyro contains a Gyro encoder flex card (flex card) mounted inside the gyro capsule at the top of the internal assembly. This flex card is the information collector for the unit and transmits information to the microprocessor.

There are two sets of LEDs and photo transmitters built into the flex card which must operate properly. By monitoring the sequence in which these transmitters turn on and off, the microprocessor determines the direction that the aircraft’s turn.

In recent years, we have determined that older flex cards are reaching their effective life limits and are now experiencing higher failure rates.

There are two primary ways this unit can fail. First if one or both output channels of the flex card fail, the heading change information will not get to the microprocessor and the unit will no detect heading changes. This will result in a heading freeze on the HSI display. This type of failure may also be intermittent.

Second there is a circuit in the unit which monitors the electric current that is being supplied to the LEDs. If the current is interrupted this monitoring circuit with cause the unit to send a flag signal to the HSI display and the red flag will drop in view.

As with the output channel failure, the heading output will freeze. There is no type of temporary repair, bypass or jumper approved by the OEM and doing so is in violation of FAA regulations.

We recommend following the OEM repair manual procedures for repairing or overhauling the DGS 65 Gyro and only using Rockwell Collins Gyro Encoder Flexcard P/N 6342252001.

Gyro Overhaul

Duncan Aviation is an authorized Rockwell Collins Service Center and is able to overhaul most Rockwell Collins gyroscopes. If you ship your gyro directly to Duncan aviation for overhaul, you could receive your gyro back in 3 to 5 days using Duncan's Aviation's AOG service.

Don't Ignore Your Aircraft's Radar System During The Winter

Aircraft Radar Preventive Maintenance

Typically, the winter months are the time of year that your radar system gets little use. You may be asking yourself, is it necessary for me to run my radar system during the winter season?

Yes!

Our experience at Duncan Aviation has shown that running your radar system during the off season does not shorten its life but may actually extend it and that of the magnetron. There is a higher instance of spoking and intermittent transmitters for customers who have not run their radar systems during the winter months.

We recommend you turn your system on every few weeks over the winter. This simple preventative measure will ensure your radar is functioning properly when you need it and hopefully extend its life.

Duncan Aviation Certifies Several STCs Under ODA Designation

  
  
  
  

Duncan Aviation

In 2013, Duncan Aviation’s Engineering and Certification departments worked diligently to complete a number of new Supplemental Type Certificates (STCs). The company’s status as an Organization Designation Authorization (ODA), along with its stringent processes and working relationship with the FAA,  allows Duncan Aviation to administer many of the aspects of the STC process that are usually controlled by the Federal Aviation Administration (FAA).

“The ultimate value of this delegated authority to our customers, both internal and external, is time, and this is an industry where time is money,” says Shawn Carraher, Certification Programs & Alterations Planning Manager for Duncan Aviation.

“Because the FAA has limited involvement in the ODA STC process, we don’t wait on them so our customers don’t have to wait, either,” he says. “That gives us flexibility with our schedules and hangar space so we can easily accommodate our customers’ long- and short-term needs. An additional benefit of this flexibility that translates directly into savings is that our customers experience shorter downtimes than they would taking their aircraft to repair stations that lack this delegated authority,” he continues.

“Delays equal dollars,” Carraher says. “Our delegated authority gives us more control over costs. We’re not waiting to turn aircraft, and our customers aren’t waiting for certification. This allows Duncan Aviation to be more efficient in completing projects and delivering aircraft as promised.”

Among many STCs that Engineering and Certification completed and issued in 2013 are the following:

  • SA01710WI   GH-3900 ESIS and Securaplane Instruments Battery Backup for Falcon 2000 & 2000EX
  • SA01717WI   High Speed Internet with Wireless Local Area Network System for Cessna 525A
  • ST01735WI   Universal Avionics EFI-890 Flight Dec Retrofit Falcon 900
  • ST01736WI   Datalink Communications System with provisions for FANS Falcon 900

SA01710WI gives Falcon 2000 and 2000EX aircraft a steady source of back-up power if the instruments lose power. SA01717WI allows for high-speed Internet so passengers in the cabin of a Cessna 525A may send and receive in-air email or stream movies from an onboard storage device.

ST01735WI and ST01736WI apply to Falcon 900s from serial numbers 001 through 178.

Additionally, the following amendment was added to an STC:

  • ST01615WI-D  Honeywell FMZ-2000 upgrade to Version 6.1 -03040

This amendment allows for a software upgrade to the Honeywell FMZ 2000 Flight Management System on Falcon 900B, Hawker 800/A/XP, and other makes. The upgrade to the Wide Area Augmentation System (WAAS)/Localizer Performance with Vertical Guidance (LVP) components let pilots navigate routes more accurately and allow for lower minimums (200 feet) for instrument landings.

ODA

The Organization Designation Authorization(ODA) held by Duncan Aviation is an appointment by the FAA authorizing the Duncan Aviation organization to perform approved functions on behalf of the FAA. On-staff and consultant engineers, flight test pilots, and manufacturing and airworthiness inspectors are qualified under the ODA to perform the authorized functions.

This designation authorizes Duncan Aviation to approve design data, analysis and test procedures, witness compliance testing, as well as make a finding of compliance to the regulations and issue Supplemental Type Certificates (STCs) for interior and airframe modifications and avionics systems and system upgrades. In addition, the ODA is authorized to issue airworthiness certificates, as well as domestic and export worthiness approvals.It has oversight from the FAA’s Wichita, Kansas, Aircraft Certification Office (ACO).

Duncan Aviation has ODA for the following:

  • Supplemental Type Certificates (STCs)
  • Major Repairs and Alterations (MRAs)
  • Parts Manufacturer Approvals (PMAs)

Duncan Aviation Unveils Double Take Design on Company Citation

  
  
  
  

Duncan Aviation's latest creative paint scheme of a Mustang.Chairman Emeritus Robert Duncan and his wife, Karen, surround themselves with the things they’re passionate about: aviation and art. So, when Duncan Aviation acquired a new Citation M2, they wanted the jet’s paint scheme to reflect the brush strokes of an artist, an abstract artist. They also simultaneously took the term “green plane” to another level with this lime green wonder.
“This is a flying billboard for Duncan Aviation’s paint department,” says Robert Duncan at the jet’s unveiling last week.

Painting an aircraft takes a significant amount of time and an incredible team. Enjoy this timelapse video of the M2's unique scheme as we celebrate another delivery from our impressive paint shop.

The paint scheme’s designer, Teri Nekuda, has 24 years of experience combining colors and materials to match a variety of customers’ needs and desires, and she used the same approach she does with all her customers when Robert and Karen asked to explore paint schemes at Duncan Aviation’s Lincoln, Nebraska, facility’s design center.

“It's enjoyable to create a paint scheme that people don't readily expect to see on an aircraft. The wow factor gets people to react, contemplate and dream of what possibilities lay on the horizon,” says Nekuda.

After more than 50 renderings, Nekuda and the Duncans had the paint scheme narrowed down to two options: a lime green or bright blue base with paint splatters dotting the fuselage. When asked to describe the final product in one word, Teri responds with “fun.”

“It’s fun on so many levels. I look at it and I start to recognize shapes and images. There’s a pair of Mickey Mouse ears over here and Woodstock there. It spurs this childlike sense of excitement and creativity. That’s a cool feeling to have at any age,” she says. 

Of course, there were several other ideas on the table before the final was approved. Robert initially wanted to explore the idea of a decal on the aircraft, allowing it to be easily changed after just a few years.

“It a great idea and I think we’ll end up using decals eventually, but this one looked a bit thick after the clear coat was applied. Also, the decal isn’t simply printed on a clear background, so any space outside the paint splotches would have to be lime green and match the paint perfectly, or have a black outline. In the end, this was too complicated of a paint scheme to try and implement decals for the first time.”

The Duncans also toyed with the idea of having graffiti on the M2, but the design team was concerned that even though the graffiti might be well-received and have a positive message in the United States, not all countries will view the symbol the same way. So when Paint Shop Manager Doug Bohac mentioned he had recently seen a motorcycle covered in paint splotches, the idea stuck.

“Robert makes me explore other ideas I might not normally gravitate toward because he gives me some direction, but not enough that he stifles my creativity with suggestions,” says Nekuda.

Even after all these changes and updates and scrapped ideas, Nekuda says it’s so rewarding to see how excited a customer gets when the project just—clicks.

“That’s when I know I’ve succeeded at something—when they can’t wipe that smile off their faces,” she says. “That’s a good feeling. That makes every minute worth it.”

Nekuda has also helped determine the paint scheme on several other Duncan Aviation aircraft.

“Robert and Karen Duncan want something unique. A lot of people like a simple aircraft, but I don’t see Robert as ever having a white airplane. We do things a little differently here,” she says.

Though the paint shop sees a lot of white jets, they didn’t bat an eye when they first received renderings of this complicated scheme. They treated the project just like it was any other customer, providing Duncan Aviation-level quality, delivered the aircraft early and celebrated another job well done.

Consequences of Vague Instructions: Sending Aircraft Units for Repair

  
  
  
  

Submitted by Jerry Cable, accessories tech rep

describe the image

Avoiding vague or incomplete instructions when sending in aircraft units in for repair and overhaul will save you hours of troubleshooting time and unnecessary expense.

Here. Fix This. 

This reminder may sound obvious, but it is amazing how many accessory units are sent into Duncan Aviation with no explanation or only very little instruction. Within the last year we’ve had a starter generator show up with no paperwork. Is it here for the 2,000 hour overhaul or 1,050 bearing change? What about the actuator with a note that simply said “repair.” Repair what? What is the squawk? When does it occur? 

When this happens we run a function test and hope the results identify the issue. However, this isn’t always a guarantee. Not all squawks can be duplicated on the bench. And many times the problem is related to other aspects of the flight or external conditions and may only fail on the bench when these conditions can be recreated. Taking note of the conditions when the component or system fails, is essential to the effective and timely resolution of the problem.

When removing any units from your aircraft, whether it’s an accessory, avionics, instrument, etc., that is to be sent in for repair or overhaul, always identify the squawk or inspection that needs attention. Having the right information about the circumstances surrounding a squawk can save your tech rep many hours of troubleshooting time and yourself a considerable amount of money.

Duncan Aviation provides accessory unit repairs and overhauls for most popular business aviation airframes. All accessory test equipment is calibrated using NIST certificate traceability. This includes three stab actuator test stands and several sets of test equipment unique to Duncan Aviation.
