Managed Repairs Program

Managed Repairs Programs manage all aspects of aircraft parts repairs so you can focus on other important things.

An Aircraft Parts Managed Repairs Program helps operators to better manage their aircraft parts repair maintenance projects by streamlining the quote process, cutting through red tape and consolidating unit shipping. The program manages all aspects of aircraft parts repairs from quote to delivery, giving operators the freedom to focus on other important aspects of operating their aircraft.

Before you continue to ship multiple aircraft units to different locations, explore the advantages of an Aircraft Parts Managed Repairs Program. 

One Point of Contact

A Managed Repairs Program contacts all vendors and consolidates quotes into one proposal. No matter how many units you ship for repair, you only review and approve one contract. The program will manage all vendor warranties for each unit.

Advanced Customs Clearance

Providing part and serial numbers to program administrators in advance of shipping the units can save you as much as two weeks shipping time and high import fees. A Managed Repairs Program can assist with pre-clearance through U.S. Customs for all units sent into the U.S.for maintenance.

Consolidated Freight Charges

Operators utilizing an Aircraft Parts Managed Repairs program may ship all units scheduled for repair to one location, eliminating the hassle of managing multiple addresses and contacts.  After overhaul or repair, all units are returned in one shipment or according to operator’s requirements.

Advanced Shipping Notice & Control

As an operator, you are free to determine how and when your units are returned.

No Hidden Terms

With a Managed Repairs Program there are no hidden terms or fees. All payment terms are determined up front, prior to return shipment.

Duncan Aviation offers an Aircraft Parts Managed Repairs program, free to all operators who want to reduce paperwork, minimize freight costs and get faster results. They provided extensive repair and overhaul services—including exchanges—for business aircraft parts, avionics, instruments, accessories and propellers. We maintain a large inventory of business aircraft parts for sale. We also hold more than 70 manufacturer authorizations for avionics, instruments, accessories and propeller units.

Five Reasons to Pursue a Degree in Avionics

Posted by Diane Heiserman on Wed, Aug 17, 2011 @ 11:08 AM

Contributed by guest blogger Philip J Reed, Redstone College

Falcon 2000 Cockpit Panel

With a degree in avionics, the most advanced aviation avionics technology is at your fingertips. Literally.

Aviation has a long history, and it’s a field that has only grown more sophisticated with time. If you catch yourself looking up every time an aircraft flies overhead and are fascinated with how fast technology is changing, it may be time to combine your passions and seek a career in aviation avionics. Here are some reasons people find the profession appealing.

Science & Technology Excite You

Aviation avionics technicians work with the most advanced and sophisticated technology today. Avionics systems aboard an aircraft include aircraft navigation and radio communications, weather radar systems and other instruments and computers that control flight, engine and other primary functions. The training to become a qualified in this field encompasses several subjects. In school, students will study radio communication theory, avionics systems line maintenance, and avionics system integration. Avionics students also benefit from an intensive study of math, physics, computer science, electronics, mechanical drawing and other similar disciplines because aircraft are complex machines.

You Thrive on Responsibility

Avionics technicians keep the world's aircraft flying safely and efficiently. Avionics systems are an integral part of aircraft design and newer technologies are continually integrated to increase an aircraft’s capability and safety. The expertise and training of an avionics technician keeps thousands of travelers safe in the air on a daily basis. Students completing electronics/avionics courses receive a Federal Aviation Administration (FAA) certification.

Quality Schools Available

The 2010–2011 edition of the Occupational Outlook Handbook notes that there are approximately 170 FAA-certified schools in the United States, and about one-third offer degrees in avionics, aviation maintenance management, or aviation technology. By law, certified mechanic schools must provide students with at least 1,900 class hours, which usually takes between one and two years to complete and also includes instruction in how to use tools relevant to the job.

Improving Your Job Prospects

While some avionics technicians are able to learn their skills through on-the-job training, most will find that they require formal avionics training to develop the skills necessary to be successful in their work. Technological advances have changed the face of avionics, and it’s important that new avionics professionals have relevant training to meet these demands.

Career Options

Because avionics is involved in everything aboard an aircraft, including engines and flight controls, the aviation industry needs skilled individuals with aircraft avionics training. Avionics technicians may find themselves involved in testing, calibrating, troubleshooting and repairing avionics instruments. Avionics jobs may also require candidates to inspect and maintain electrical systems as well as set up and perform bench tests, repairs and replace defective components such as tachometers, temperature gauges and altimeters, as well as read electrical wiring diagrams. Graduate and post-graduate degrees generally aren’t available in avionics, but some people choose to move on to earn an engineering degree.

If you’re a thorough person with the self-motivation and work ethic required to have a good career, you could be a good fit for work in avionics. Study hard, and keep learning to give yourself the best prospects possible.

16 Important Aircraft Parts Sales & Core Exchange Terms

Posted by Diane Heiserman on Tue, Aug 02, 2011 @ 10:58 AM

Contributed by Jewell Chambers, International Sales Representative

alphabet soup

The acronyms and terms used in aviation are an alphabet soup. It can be very confusing and seem like a foreign language.

Entering into an agreement without fully understanding the language in an aircraft parts sales or exchange quote can cause confusion, delays and customer frustration. Never enter into an agreement to purchase or exchange aircraft parts, before fully understanding the terms and conditions of the contract.

Below are 16 aviation acronyms and terms typically used in aviation parts sales and exchange quotes.

ARO —After Receipt of Order

Part order must be placed prior to part being shipped. An ARO quote is good for a limited time only.

AOG—Aircraft On Ground

AR—As Removed

The part is being sold in the condition it was in when removed from the aircraft.

Consignment Inventory

Parts are being sold on behalf of someone else. Consignment Inventory parts may not have traceability.

C—Core

Unit or part being returned from an exchange sale.

ETA— Estimated Time of Arrival

Estimated time when a part will arrive.

Exchange

A unit or part sold to a customer in exchange for the same core unit in return.

Late Fees

Additional charges for core returns being returned late. Most vendors give 14 or 21 days to return core units, after which, extended use fees, late fees and even outright billing may apply.

LT—Lead Time

Amount of time until the unit or part is available for shipment.

OEM—Original Equipment Manufacturer

Outright Sale

No core return is expected from the customer (i.e. not an exchange unit).

OHC—Overhauled

A unit or part repaired per an overhaul manual.

SVC—Serviceable

A unit repaired to satisfy a declared squawk only. It is not an overhauled unit.

Squawk

Explanation or description of why a unit has failed.

WOR—Work Out of Repair

Unit needs repair attention before available for sale.

Duncan Aviation provides extensive repair and overhaul services—including loaners and exchanges—for business aircraft parts, avionics, instruments, accessories and propellers. We maintain a large inventory of business aircraft parts for sale. We also hold more than 70 manufacturer authorizations for avionics, instruments, accessories and propeller units.

With more than 370,000 line items, including tens of millions of dollars in rotables, and a huge inventory of avionics, instruments, propellers, parts, components and consumables of all kinds, we can usually handle your aviation parts or core exchange needs from our current stock.

How ITAR Could Delay International Aircraft Parts Shipments

Posted by Diane Heiserman on Thu, Jul 28, 2011 @ 01:27 PM

Contributed by Don Heinlein, Domestic & International Parts Team Leader

parts shipment

Proper documentation will get aircraft parts more easily approved by the U.S. Dept. of State to pass through U.S. Customs without delay.

Operators are sometimes unaware that parts or units listed on the United States Munitions List (military items) must meet specific requirements to be shipped to the U.S. Without proper authorization, shipments can be delayed at the border for months. Here’s what you need to know to avoid delays.

The United States Government has International Traffic in Arms Regulations (ITAR) pertaining to the import and export of parts or units on the United States Munitions List.

ITAR items shipped to theU.S.are not allowed into the country unless the company or person shipping the item (shipper) has registered with the U.S. Department of State (DOS) and has obtained an import license, or that the shipment qualifies for a license exemption.

If items are shipped to the U.S.without this prior-authorization, they maybe held at the border for up to 60 days while the DOS decides whether to approve their admittance into the U.S. 

To prevent days and weeks of delays, I highly recommend you notify your U.S.aircraft parts service provider prior to shipping any aircraft parts for repairs or exchange cores. They should be able to identify if the part is ITAR controlled and provide the proper language required for the commercial shipping invoice.

If your chosen aviation parts service provider is not knowledgeable of U.S. ITAR, is not capable of pre-clearing your shipment or is not able to provide the necessary language and paperwork for your shipment to enter the U.S., stop and find one that is.

Duncan Aviation screens all incoming shipments for ITAR-controlled items and provides our broker with the proper information for U.S. Customs so the parts are easily approved by the DOS and pass through U.S. Customs without delay. We monitor all shipments as they go through this process and will swiftly deal with any delays in a timely manor.

To ship parts to Duncan Aviation, please complete a shipping notice form.

Duncan Aviation provides extensive repair and overhaul services—including loaners and exchanges—for business aircraft parts, avionics, instruments, accessories and propellers. We maintain a large inventory of aircraft parts for sale. We also hold more than 70 manufacturer authorizations for avionics, instruments, accessories and propeller units.

How Not To Ship Business Aviation Core Returns

Posted by Diane Heiserman on Thu, Jul 07, 2011 @ 02:07 PM

Contributed by Stephen Narciso, International Parts Sales Rep.

I shake my head in amazement every time a box arrives at Duncan Aviation returning units from a core exchange with no thought or care taken to ensure the units are not damaged during shipping. Aviation core returns are often worth tens of thousands of dollars and extra steps are necessary to carefully pack them for shipping.

Any damage sustained during the shipping process due to poor packing is not paid for by the shipping companies or insurance. This expense is the responsibility of the customer.

Below are photos of a recent shipment received by Duncan Aviation and an excellent example of how not to ship aviation parts.

bad core exchange packing

Too small

This small box is barely large enough for just the parts and doesn’t leave any room for padding.

poor core return packaging

Too weak

Weak boxes provide no protection for units inside. This one might as well have been shipped in a paper sack.

poor core return packing

Too much

Packing all these units into this small box cost this customer more money than it would have if he would have shipped them separately.

crushed indicators

Crushed

Cellophane wrapping does NOT provide protective padding. Both indicators have been crushed.

cracked cabin indicator

Cracked

Three units were wedged together in one box resulting in the front glass bezel of this Cabin Indicator to be cracked.

starter generator shipping damage

KO’d

This starter generator has taken a brutal beating. The rear housing, rear-end piece, studs and vent tube are severely dented, crushed or bent. In addition, several pieces of the terminal block have broken off. 

This customer could have avoided the estimated $15,000 replacement cost with a little more time and effort put into making sure these units were securely protected for shipment. Unbelievable, isn’t it? However, this happens more often than you might imagine.

It is pretty simple to avoid these types of shipping problems.

  • Use boxes large enough
  • Use boxes strong enough
  • Always use plenty of the right type of packing material
  • NEVER ship heavy items and fragile items in the same box

Aircraft Parts: Exchange or Repair?

Posted by Diane Heiserman on Thu, Jun 16, 2011 @ 09:47 AM

Contributed by Vince Cruickshank, Parts Inventory Manager

Balancing time and money

Deciding to exchange or repair aircraft parts boils down to time and money. And how much you have of each.

Your aircraft’s main landing gear is in need of service. Do you exchange it or have it repaired?

This question is always on the minds of aircraft owners, operators and Director of Maintenance and applies to any aircraft part, avionics, instrument, accessory or propeller unit in need of service. 

There are several issues that may cause you to lean one way or the other. But it basically boils down to two key factors: time and money and how much you have of each.

1. Is a longer downtime acceptable?

The more cost-effective way to have your unit serviced is to send it in to a qualified avionics, instruments, accessory or propeller repair facility to have the maintenance performed. It will require a longer downtime, but the unit will be returned in serviceable condition.

2. Is the part needed as soon as possible?

If time is not on your side and you need to meet a tight flight schedule, you will want to consider exchanging your unit for one already in serviceable or overhauled condition. Although this option will cost you a little more, the exchange unit can be shipped the same day to get your aircraft back in the air with minimum downtime. One additional advantage is that a door to door carrier service can usually get the exchange unit to you the same day you order it.

Duncan Aviation provides extensive repair and overhaul services—including loaners and exchanges—for business aircraft parts, avionics, instruments, accessories and propellers. We maintain a large inventory of business aircraft parts and consumables of all kinds. Find the part you are looking for by searching Duncan Aviation’s Inventory of parts and capabilities

3 Things to Look for in a Business Aircraft Autopilot Support Team

Posted by Diane Heiserman on Fri, Apr 22, 2011 @ 02:44 PM

Contributed by Kevin Miesbach, Avionics and Instruments Shop Manager

computer wifi troubleshooting

Duncan Aviation's Avionics Tech Reps, Curt Campbell and Larry Troyer help operators troubleshoot squawks and coordinate autopilot repairs.

The autopilot is a vital component on an aircraft. When it isn’t functioning properly, there can be all kinds of problems. There aren’t many places where operators can find the autopilot knowledge, experience and technical expertise all in one place.

What if operators could create their own autopilot team? They would be able to troubleshoot the system in the aircraft more efficiently, ensure the right box or boxes are removed for repair, access autopilot loaners while equipment is in for repair and schedule appropriate turn times.

Here are three criteria to look for when selecting an autopilot support center.

1. Autopilot Technical Experts

Sometimes an experienced technical representative can ask questions to walk an operator through a series of troubleshooting steps over the phone. However, being able to troubleshoot an autopilot squawk over the phone requires an intimate knowledge of the system and how it works on all airframe models. Qualified autopilot tech reps are able to troubleshoot and isolate autopilot problems on aircraft over the phone and by utilizing test flights for the more intermittent glitches.

2. Autopilot Customer Account Support

Customer service is very important when an autopilot needs to be repaired. Account reps should be intimately familiar with scheduling and turn times associated with different types of autopilot equipment. They should also maintain good communication with avionics teams, and be knowledgeable about which technicians are most experienced with the autopilot specific to an operator’s aircraft. If the need arises, they should also be able to connect an operator directly to the avionics tech to clarify squawk information or quote options.

3. Skilled Autopilot Leaders

Managing a team of autopilot technicians, coordinating test equipment and ensuring downtimes are met has its challenges. Verifying a squawk for a simple function check can exceed eight hours on some a/p computers. A skilled autopilot team leader can use their resources effectively to repair and return an autopilot on time and on budget.

Duncan Aviation’s Component Solutions team includes autopilot technical experts with the expertise and capabilities to work on many aircraft models, including Learjet, Citation, Falcon, Challenger, Hawker, Westwind/Astra, King Air, Piper Cheyenne and Rockwell Commander. Search our aircraft parts and capabilities list to verify our expertise on your autopilot. For more information please call Duncan Aviation's Avionics Customer Account Reps or Technical Representatives.

2 Questions to Save Downtime, Costs for Aircraft Avionics Repair

Posted by Diane Heiserman on Thu, Mar 31, 2011 @ 05:08 PM

Contributed by Don Fiedler, Manager of Component Solutions Business Development

Avionics Directional Indicator Repair

Being aware of the circumstances surrounding any avionics component or system failure will save you time and expense.

Having the right information about the circumstances surrounding a squawk can save your avionics tech many hours of troubleshooting time (and yourself a considerable amount of money) for an avionics repair.

When a unit arrives at the shop for repair, sometimes the squawk is obvious; however, there are many times when it is not. Before sending in your unit for repair, be prepared with the answers to these two questions.

1. When does the squawk occur?

  • Does the unit get too cold on the ramp (wintertime) or at altitude?
  • Does the unit get too hot (summertime) or after the unit has been in operation for a while?
  • Does the squawk occur intermittently?

2. What happens at the time of the squawk or its resolution?

  • Is there vibration? Some aircraft produce more vibration than others.
  • Is it overheating after long operation?
  • Is there poor or no cooling to the unit?
  • If the unit gets too cold at altitude and is located outside the cabin, what does the OAT indicate?
  • Does the squawk occur in precipitation?

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.

It’s also important to communicate this information when you ship the unit in for repair. It’s always a good idea to include a printed copy with the unit, and to follow-up a phone conversation with an e-mail of the critical details.

To find out more about Duncan Aviation's avionics repair services, contact an Avionics/Instruments Customer Service Representative.

The Five Most Exotic Duncan Aviation Road Trips of 2010

Posted by Diane Heiserman on Thu, Jan 06, 2011 @ 11:27 AM

Contributed by Erin Hart, Duncan Aviation Apprentice

Egypt road trip

After working with the Egyptian Air Force on engine training for their Falcon 20, Engine Tech Rep Shane Heier and his wife Katie took a few days to travel Egypt.

Duncan Aviation provides emergency AOG support to grounded aircraft nearly anywhere in the world, making hundreds of service trips a year. In 2010, team members traveled to some of the most exotic locales including such places as Puerto Vallarta, Mexico; Guayaquil, Ecuador; Merida, Mexico; Cairo, Egypt and St. George, Bermuda. While providing the most-needed AOG services to our customers at their location, team members also took in some local culture, food and sites.

Puerto Vallarta, Mexico

In the spring of 2010, avionics tech Gene Dannenberger flew from the Duncan Aviation avionics satellite shop in Sacramento, Cal., to Puerto Vallarta, Mexico, to install a Duncan Aviation repaired radar system in a Jetstar. While there, Gene took advantage of the wonderful weather to become a sightseer at many of the local tourist spots including downtown Puerto Vallarta, the marina and of course, the beach.

While performing this routine maintenance, he was entertained throughout the day with music playing in some nearby trees and was visited by a couple of armed airport guards who came out to watch the radar change.

Guayquil, Ecuador

A quick trip to Ecuador for one Duncan Aviation Engine Rapid Response Team (RRT) technician turned out to be more than expected one day in July. After arriving, Karl Johnson, Rapid Response Team Leader from Fort Lauderdale, Fla. went to work troubleshooting the squawk and quickly discovered a faulty oil pump. James Holmes, an engine tech also from the Fort Lauderdale RRT, hand-delivered the part in order to complete the project on time for the customer. Together they completed the maintenance and headed back to Florida, arriving at 6 a.m. the next morning.

In reflection, Karl admitted that the trip was too short and had he been able to stay longer would have visited a local establishment known for having great steaks.  

Merida, Mexico

Karl's trip to Central America didn’t end in Ecuador. He took three separate trips to Merida, Mexico in a span of about two months. What began as a fuel control change turned into troubleshooting for a compressor stall. Finally, the project came full circle with an engine change two weeks later.

This trip, even with the short time and busy schedule, Karl did find time to enjoy the nice people and good food of Merida, Mexico. “I didn’t have the extra time to learn about the area and culture, but I now know how to drink a Mexican beer the right way.”

If he ever gets the opportunity to return, Karl hopes to visit the Mayan Pyramids.

Cairo, Egypt

Shane Heier, an Engine Tech Rep out of Lincoln, Neb. traveled over 4,000 miles to Cairo, Egypt not once, but twice in 2010. For six days in the heart of the Arabian Desert, Shane’s first trip provided the Egyptian Air Force LRU training for the Honeywell TFE731-5BR engine on their Falcon 20.

Taking advantage of his time in Egypt, he and his wife Katie stayed an extra couple days traveling the region and exploring a land rich in history. Their adventures took them to the Pyramids of Giza, the Cairo Museum, a church in Coptic Cairo and a visit to the Alexandria Library of Alexandria located along the Mediterranean Sea.

A month later, Shane got the chance to visit Cairo again and was accompanied this time by Jeff Sikes, RRT engine tech from Scottsdale, Ariz. Duncan Aviation's Rapid Response Teams support AOG engine emergencies in addition to most scheduled and unscheduled events, including engine changes and that is exactly what brought the two to Cairo. They were dispatched to change an engine for a Dassault Falcon 20 aircraft onsite.

Shane’s time in Egypt was an experience he will not forget and remarks that he would visit again if given the chance.
