Duncan Aviation’s Astra History

Posted by Kate Dolan on Thu, Mar 26, 2015 @ 09:53 AM

TimGarityTim Garity, a longtime Tech Rep with Duncan Aviation, loves aviation, but he also enjoys the people he has met along the way.

Like many 18-year-olds, he joined the military so he could see the world. Originally from Erie, Pennsylvania, Tim was thrilled to be stationed on a naval aviation base in Hawaii and rotate from there to bases in Thailand, the Philippines and Japan. His stint in the Navy did more than offer travel opportunities; through it, he found his calling in life.

In 1977, Tim began working in the business aviation industry. In the intervening years, industry changes have been numerous and momentous, and he has enjoyed being on the forefront of aviation technology and mechanics.

However, what he values most are the ongoing, long-term relationships he’s established with Duncan Aviation customers over the years – particularly those who own Astra aircraft.

“I’ve enjoyed working on the Astra because I know the aircraft pretty well, and I’ve always thought the Astra is a well-built, easily maintained plane,” says Tim.

Tim first learned about the Astra in 1985, the year they were type-certificated. And in his Tech Rep position at Duncan Aviation, he began working on the newly certified Israel Aircraft Industries’ Astra in 1986.

“Astras have a niche in the industry where the pilots and mechanics both really like the aircraft,” says Tim.  “Owners who have bought one tend to buy them again and again.”

It’s All About Relationships

Phil Carrell, Director of Maintenance at Cin-Air, shares Tim’s long history with the Astra. Phil went to A&P school at the Somerset State Vocational Tech school in Somerset, Kentucky, and the opportunity for hands-on experience is what drew him to aviation in the first place.

“When I was growing up in Bloomington, Indiana, my next door neighbor built airplanes in his garage,” says Phil. “It intrigued me that someone could build an airplane out of nothing.”

In the late 1980s, Cin-Air managed a fleet that included a Citation II, a Westwind and a King Air, and looking to replace the Westwind, Phil’s boss began researching the Astra. They had worked with Duncan Aviation in the past, so when they decided to add to their fleet, they contacted Rene Cardona, a member of Duncan Aviation’s Aircraft Sales and Acquisition team.

“We had worked with Rene in the past and trusted his recommendations,” says Phil. “Our boss believed that the Astra would be a good fit for our company, and when Rene confirmed it, we decided to fly over to the UK and take a look at one.”

In 1990, Phil and Tim traveled to Manchester, England, to look at an Astra SP. Based on that assessment and the market information Rene had provided them, Cin-Air bought the Astra.

Extending the Family

“We liked the economics of the Astra and appreciated its operational capabilities; it was a high-speed, long-range aircraft with a stand-up cabin, and it had all of the latest comforts,” says Phil. “The Astra was a great airplane, and I loved to fly it. It was reliable, and I got to know it well over the years.”

In 2000, Cin-Air added another SP to its fleet because they were so pleased with the aircraft’s reliability. Cin-Air kept the first Astra SP for about 14 years, and in 2004, traded it in for an SPX. Last year, they traded both Astra aircraft for a G200.

“We like the G200 quite well; it was the second in our fleet,” says Phil. “We got our first G200 brand new in 2006. Because we know and like this airplane, and it’s in the same family of aircraft, we bought a third, so now our fleet consists of three G200s.”

Despite changing the composition of the fleet, one thing has remained fairly constant in the last two and a half decades: Cin-Air has turned to Duncan Aviation to service its fleet and provide sales assistance on many occasions.

“When we need refurbishments or paint, I always call Tim Klenke,” says Phil. “My company and I have always valued our relationship with Duncan Aviation because of the honesty and integrity of everyone at the company. Honesty is paramount in our business. We will absolutely continue to do business with Duncan Aviation, and we’ve started taking our aircraft to the Battle Creek, Michigan, facility because it’s so much closer for us.”

Multi-Shop, Multi-Site Embraer 144-Month Success Story

Posted by Diane Heiserman on Tue, Jan 06, 2015 @ 08:00 AM


Submitted By Jeff Schipper, Project Manager PVU

Duncan Aviation’s Provo, Utah, facility both gave and received an early Christmas present this year in the guise of an Embraer Legacy 144-month (L24) inspection. During this inspection, we restored the landing gear and installed an Aircell ATG5000 cabin Wi-Fi system, among many other smaller items.

Space constraints presented the Provo crew with unique challenges, but with the requested outdate in mind, our teams worked together and creatively resolved those challenges. We aggressively dealt with the turntimes on the landing gear in order to meet our customer's limited downtime. The landing gear team at our Lincoln, Nebraska, facility finished the overhaul and shipped the landing gear back to Provo within a day of the requested return date.

Another challenge resulted from a missing aircraft Electrical Load Analysis (ELA) document. The ELA is comparable to the aircraft Weight and Balance Manual—only it’s for the aircraft electrical system. Our avionics install team worked with our Embraer contacts and procured a manual for this serial number in time for our team to perform the final calculations and produce the appropriate paperwork on our end for delivery.

To limit yet maximize downtime for this popular charter aircraft, our interior team worked with the customer on which repairs we could accomplish after the interior was removed for the inspection. The team ended up finishing several high-profile pieces of woodwork and had everything looking like new by the time installation day rolled around.

As often happens, a couple of gremlins dogged the final day—a landing light burned out and a flow pack gave up just before delivery. Troubleshooting and procuring parts ended up pushing delivery back a day, but the aircraft arrived at its home on Tuesday, December 23.

Once home in Scottsdale, the delivery gremlins reappeared; this time, an APU issue sent our Scottsdale Rapid Response team into action and they resolved the issue by early the following morning. 

One of the things that really shined through to our customer with this project was the way Duncan Aviation as a team banded together to support them no matter what facility they were in. This aircraft was worked on in our Provo facility, the landing gear was completed at our Lincoln location and when the aircraft needed after-delivery support in Scottsdale, our Rapid Response team there was quick to respond. This inspection was a true multi-shop, multi-site success story.

Since becoming a Legacy Authorized Service Center, we’ve completed several types of inspections, including L1, L2, L4, and this most recent L24.

Jeff Schipper is a Project Manager at Duncan Aviation's Provo, Utah, facility serving as the central point of contact for his customers' projects ensuring overall project quality and timely aircraft delivery. His aviation career began in 1987.

Aviation Nondestructive Testing

Posted by Duncan Download Blog on Thu, Jul 10, 2014 @ 11:09 AM


Fluorescent magnetic particle inspection on a generator dampener plate.

Nondestructive testing, or NDT, is a method of testing for defects in materials without destruction of the materials.

There is some form of NDT testing on nearly every aircraft inspection. It is often required to test aircraft parts, assemblies and other materials to determine if useful life remains or if cracks or corrosion hide below the surfaces.

Eddy current, dye penetrant, ultrasonic and magnetic particle inspections are all NDT methods used for required NDT testing. For major structural inspections on several aircraft models, NDT x-rays are required.

Duncan Aviation has one of the highest skilled in-house non-destructive testing teams in the industry. All technicians are trained and certified for basic Falcon NDT and several certified for advanced Falcon NDT testing. 

It is what they do full-time every day, day in and day out. They do not divide their time with other areas and work NDT part-time. 

The team currently has 8 certified NDT technicians, but to meet increasing demands, both internal and external, more certified NDT technicians are being added. 

Capabilities in Lincoln, Nebraska, are being expanded to include Bombardier Global and Embraer aircraft. And an NDT lab will open soon in Provo Utah. 

Duncan Aviation believes that being prepared to meet the smallest needs of every customer has the biggest impact and has invested millions of dollars in tools, equipment and talent to quickly and efficiently provide for required aviation maintenance services.

Don't Forget The Pre-Buy 6

Posted by Duncan Download Blog on Wed, Jul 02, 2014 @ 02:42 PM

When buying or selling an aircraft, nothing can be more stressful than the "moment of truth"–that point in the transaction where the buyer and seller are presented with the aircraft squawk list and it is time for them to negotiate and finalize. Partnering with a service provider who knows how to clearly present its findings and communicate well with all parties involved can allow the key players to breathe a bit easier.

"Pre-purchase evaluations are complex, there’s no way around it," says Tim Klenke, an airframe service sales representative with Duncan Aviation. "Stress can be tempered somewhat, though, when the pre-buy evaluation occurs at a facility with a good reputation, excellent communication and integrity."

Pre-purchase events and aircraft purchases are uncharted territory for many operators. There are a lot of people involved, lots of choices to make and usually some surprises along the way.  

Here are Tim's suggestions on what to look for when selecting a service provider for a pre-buy evaluation.

Top 6 Things When Selecting a Pre-Buy Provider

  1. Reputation. How is the facility viewed within the industry?
  2. Experience. How many pre-buys does a facility perform? Do the buyer and seller feel comfortable with the provider and have confidence in the provider’s ability to understand and execute the pre-buy according to the terms and conditions of the buyer/seller agreement?
  3. Post pre-buy capabilities. Can the facility perform interior work, exterior paint, avionics upgrades and larger inspections?
  4. Import/export proficiency. Does the facility have these services if the airplane is coming from or going overseas?
  5. Communication. This skill is critical in pre-buys; everything must be crystal clear and understandable for all parties – buyers, sellers, brokers, lawyers and the service facility.
  6. Technical support. Does the facility offer in-house Technical Representatives for each model airplane who can engage quickly with OEMs and teams to resolve unexpected issues without disruption in schedule?

Pre-Buy 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.

Duncan Aviation's New Hangar Goes Green

Posted by Duncan Download Blog on Wed, Jun 04, 2014 @ 12:29 PM

Duncan Aviation new business aircraft maintenance hangarThis summer, Duncan Aviation will complete the largest expansion project its Lincoln, Nebraska, campus has ever seen. The 175,000-square-foot facility will be comprised of two 40,000-square-foot maintenance hangars and a 95,000-square-foot office and shop space.

As the industry continued to trend toward larger business aircraft, Duncan Aviation recognized their current hangars would soon be unable to accommodate the volume of maintenance, modifications and completions work their customers requested and required. This industry shift is fueled by technological advances and increased globalization

Chief Operating Officer, Jeff Lake said the company decided to build now because the size and number of aircraft they are working on and will continue to work on simply did not fit well in the current hangar space.  

“We anticipated this trend, which is why we invested in the new 45,000-square-foot aircraft paint facility two years ago. Now it was time to support the maintenance side,” Lake said.

Duncan Aviation already boasts a row of hangars that dot the runway at Lincoln’s Municipal airport. Now as the expansion is nearing completion, they will add two more.

Going Green

When Duncan Aviation’s Senior Team decided it was time to invest in a new, larger hangar facility, they wanted to ensure it was of the highest quality, just like the aircraft services provided inside. That priority also aligned well with the company’s desire to make “green” decisions whenever possible.

“Things that are good for the environment are good for our employees, and that translates into an excellent experience for customers as well,” Lake said.

Kyle Link, Tectonic Management Group, Inc.’s designer/builder senior project manager for the expansion said the materials and design elements chosen are a new concept in hangar environment. From the LED lighting that senses daylight and automatically dims itself to the radiant floor heating, it’s top of the line.

“You can’t cost effectively dim fluorescent lights. You would have to shut off individual bulbs. But LED lights can be dimmed gradually, saving energy and making it less apparent to team members,” Link said. That combined with the skylights and windows, makes the hangar brighter with all the lights off than any of the other hangars with every bulb lit.

During construction, Duncan Aviation made deliberate decisions to go above and beyond the energy code and choose more cost and energy-saving options such as skylights, sidewall daylight panels and radiant floor heat.

“It was really an easy decision to invest a bit more up front and do what’s right for our environment, especially if it means we’ll save money in the long run,” Lake said. “With as quickly as technology changes, we need to be a bit ahead of the game.”

Duncan Aviation in 2014: New Year…New Hangar…More Space

Posted by Diane Heiserman on Thu, Jan 09, 2014 @ 08:00 AM

Duncan Aviation's new maitenance hangar Duncan Aviation's new maitenance hangar

Can you think of a better way to begin the new year than to open the doors to a brand new aircraft maintenance hangar? Neither can we.  And on Monday, that’s exactly what we did. The clean and freshly coated floors of Duncan Aviation’s newest 40,000 square-foot maintenance hangar were christened as four business jets, including one Falcon 7X were ushered in during near-record low temperatures and blowing winds, two weeks ahead of schedule!

And we’re not done!

Although this new hangar is large enough to hold the largest model business jets in operation, this is only phase one. Another 40,000-square-foot maintenance hangar and a 95,000-square-foot office and shop space, will be completed and ready for use in June of this year. Altogether, this maintenance structure is the largest expansion project Duncan Aviation’s Lincoln campus has ever seen.

The expansion comes in response to customer requests and changing customer needs. The business aviation industry continues to shift toward larger business aircraft, a trend fueled by technological advances and increased globalization.

There has been considerable buzz and anticipation for Duncan Aviation’s expansion in Lincoln, Nebraska. At last check (only moments ago), all available space is occupied and 18 more large-body aircraft are scheduled for multi-week maintenance events during the first quarter. With nearly 20 more waiting to be placed on the schedule for hangar floor space through the middle of the year.

If you are wanting to get your business jet on the schedule and in this new hangar for the coming year, don't hesitate. Space is limited and it is filling up fast. Contact a Duncan Aviation sales rep today.

We are excited about this expansion and want to share it with you. Let me personally invite you to come visit Duncan Aviation and see firsthand our commitment to our customers, our team members and business aviation.

Taking Advantage of Downtime While at Duncan Aviation in Provo, Utah

Posted by Diane Heiserman on Mon, Dec 23, 2013 @ 11:20 AM

Utah Adventures

Panorama of southern Utah Lake.

Don’t know what to do while your aircraft is at Duncan Aviation for a multi-shop inspection for several weeks? Here is a detailed travelogue from Mariusz Wieczorek, a Duncan Aviation customer from Poland who spent several weeks downtime at Duncan Aviation for an 8C inspection. 

Read about his firsthand account on what to do, where to go and who to talk to when on the ground at Duncan Aviation in Provo, Utah.

Maybe it’s because I come from a country where summer time usually looks like Scotland’s fall. Maybe it’s because I’ve never left my continent before, but one this is for sure–after spending time in Provo, I can definitely say or rather shout: “I love Utah!”

I knew nothing about Provo or Utah before it was decided we were going to have Duncan Aviation perform an 8C check on our business aircraft at their facility located there. Though I’d heard about places like Salt Flats, Salt Lake, Bryce Canyon and Zion’s National Park, I was eager to do some exploring on my own. The entire state offers a vast and beautiful, sometimes dangerous landscapes where you can hide for days having only bear, wolves and mountain cats as company. You may even find a deer blocking your car in the parking lot.

After you’ve landed at Duncan Aviation in Provo, Utah, (PVU) and conducted business setting up maintenance and repair schedules, leave your aircraft in their capable hands. Let them do their job. They know what they’re doing.

Hiking, Biking, Flying and More!

There is no need to travel far to see the beauty of the state. If you like hiking, Mt. Timpanogos (elev. 11,752 ft.) is the highest peak within a few miles of Provo to scramble on. Go north through beautiful Provo Canyon on your way to the Aspen Grove Trailhead. Make sure to stop at the Sundance Resort along the Alpine Loop Scenic Byway for a decent meal, because you’re going to need it! During this 8-10 hour scenic hike, you will cross beautiful waterfalls, stand at the edge of Emerald Lake with its glacier and see curious mountain goats or possibly a moose or two before you reach the summit. The 360 degree view is astonishing and will make all the effort worth it.

Mt. Nebo (elev. 11,928 ft.), is another nearby peak 20 miles to the south. The Mt. Nebo Loop is a scenic serpentine on your way to the trail head. This hike is not for the faint of heart. Prepare yourself for a real cardio workout, especially the last mile when the trees stop and birds find no reason to fly there. After you summit, return down the same trail or if you feel up for more physical challenges, continue on through the middle and south Nebo peaks for your descent.

For the most extreme climbing experience, visit Little Cottonwood Canyon north from Provo. You’ll find nice boulders and unique climbing roads cut in the granite walls of the canyon.

Talk to Jason Kinnan, Duncan Aviation’s Parts Specialist in Provo. He is a local Search and Rescue member and knows everything about mountains and climbing.

If you are a biker rather than hiker, there are plenty of roads that lead to some special places. Most of the mountain roads are easily accessible and paved with race cyclists riding all over the place. If you prefer endurance cycling, visit Park City, Utah. Canyon Resort and Sundance Resort are nearby with various trails from easy to hardcore. Rent a downhill bike and have a blast. Remember to wear a helmet and crash pads!

Talk to Glenn Lewman or Shawn Mortensen, two of Duncan Aviation’s airframe mechanics in Provo. They will take you to unique trails in the wilderness far away from bike parks.

Need to get back in the air? Rent a glider, airplane or instructor at Heber City Airport, then fly the very same mountains you just hiked or biked. This is the easiest way to summit. You will experience thermal and ridge lift and possibly even wave activity when in the air. It’s all there.

Just three short miles from Duncan Aviation in Provo, head for Utah Lake State Park. There you can rent a motorboat, ski jet, catamaran, and sailboat. Float down the Provo River in a canoe, take a kite surfing lesson or just lounge on the warm sand and relax.

Are you a golfer? Good. Nearly half of the Duncan Aviation team in Provo is too. They know the best courses.

If you’re visiting in winter time, the skiing and snowboarding couldn’t be any better. Utah Mountains hold the best snows in the world. Jeff Schipper, Duncan Aviation Project Manager knows the best ski areas and equipment.

If you’re a gearhead visiting in August be sure to visit the Bonneville Salt Flats Race Track to see the Speed Week event. This is the place to be for automobile fans. You’ll see speed record machines from motorcycles, cars, hot rods, trucks and many more; speeding around at speeds up to 400 mph. Ward Cranor, Duncan's Lead Structures Mechanic in Provo, is a motor head and will surely take you on a tour.

Night Life and Long Weekends

After all the adventure you can take, find a pub to cool yourself down with various products of local breweries. As a matter of fact, Utah is one of leaders in producing beer in the country and a serious exporter as well. For more night live and social, cultural activities you don’t have to go far; everything is available 40 miles north in Salt Lake City. Or just visit Las Vegas, only about five and a half hours to the south. While there, the Hoover Dam is too close not to see and the south ridge of the Grand Canyon is within grasp.

On a long weekend, head south through Vermillion Cliffs to Zion National Park, climb Angels Landing trail or go for the famous Narrows. Visit Page City and take a refreshing bath at one of Lake Powel’s wild beaches. The water is both super-clear and warm. Then next time, head north and visit Yogi Bear at Yellowstone National Park—it’s only a six hour drive. Good advice: don’t overnight in your car inside the park. You’ll have a chat with the Ranger by the light of the moon.

If you are looking for a maintenance facility that knows how to take care of your aircraft, choose Duncan Aviation. If you want the time to go faster with some off road adventure, Provo, Utah, fits the bill. In addition to incredible service, you’ll have a lot of fun and many tale-worthy experiences you won’t soon forget.

Duncan Aviation Customer Letter of Appreciation

Posted by Diane Heiserman on Tue, Dec 10, 2013 @ 07:00 AM

In August of this year, Thriveni Earthmovers arrived with their aircraft at Duncan Aviation for a large multi-shop maintenance/upgrade event. Chris Neaves, Thriveni’s Director of Flight Operations, took the time to send the following letter to Andy Fernandes, Duncan Aviation Regional Manager to India, and Rich Jones, Duncan Aviation Project Manager, regarding their experience. We decided to share these remarks because although we can say we hold ourselves to a higher standard of service than other service providers in business aviation, nothing says it quite like our customers do.

Thrivani Earth Movers

Andy and Rich,

On behalf of Thriveni Earthmovers, I would like to thank you and the mechanics of Duncan Aviation for your work on our aircraft.

We appreciate that you were able to work with a moving input date and remain flexible enough to take us with just a week’s notice. As you know, we came out of a nightmare-like situation where we had to take the aircraft to the manufacturer’s facility for some upgrades only they could perform. After a four-week overrun on their time estimate and a higher bill than expected at the manufacturer, we were relieved when we arrived at the Duncan Aviation Battle Creek, Michigan facility.

Everything about the whole Duncan Aviation experience—from the moment we arrived on the doorstep to day of departure—was amazing. Nothing was too difficult, and everyone was pleasantly open and forthcoming with both good and bad news as we completed the B, C and D check, Export Certificate of Airworthiness, repaint, a gaggle of new avionics and interior refurbishment work.

Convenient doesn’t even come close to describing and the phone app. I was able to go to the other side of the planet while still communicating with everyone at Duncan Aviation, receive photographs and explanations of issues, as well as approve and deny work orders. The website was great at describing the current expenditure and the progress when we weren’t actually onsite.

Also, no matter who you are, how big or small your aircraft is, everyone is treated as if they are Duncan Aviation’s number one customer. Any issues that arise during the work are dealt with instantly, and the attention to detail is amazing.

Our airframe work was suburb and your mechanics’ attention to detail was outstanding. Actually, every department at Duncan Aviation we worked with impressed us, including interior, paint shop and avionics. Having team members who are so skilled in their trades is quite an asset for both Duncan Aviation and aircraft owners. We experienced a significant savings when the scratches on the wood and the stains on the window shades were removed, leaving our aircraft looking nearly new. The full metallic exterior repaint of our aircraft turns heads. It is a perfect application without a single drip of paint. We are impressed with the aircraft’s overall appearance. The end result exceeded our wildest imagination. Also, your ability to modernize our entertainment system, integrating the new with the old means we now have a system where every cabin seat can listen or watch their own individual selection, or surf the internet, or both—something you never see in a jet this size.

Considering the scope of work, the timeframe we had available and the added full repaint, we were astonished that we came out a day early with a refund, not a bill.

Normally when you do this much work in a short span of time like we did, the last couple of days are a mad rush and it’s a flurry of paperwork to complete, bills to pay and a scramble to ensure nothing was missed, but not at Duncan Aviation. We encountered the simplest, smoothest experience at the end I have ever seen. It also helps that people at Duncan Aviation think ahead, treat the plane and work as if it’s their own aircraft and don’t leave anything to the last minute.

The quality of the Duncan Aviation workmanship was apparent when our aircraft was released for service just a couple of hours before our departure, and we were able to fly to the other side of the world without any faults or problems. Our aircraft performed flawlessly and flew like new, and it still does a month later.

We are starting the process for our next aircraft purchase and will not even consider looking anywhere else but Duncan Aviation for the work on it. With your new Indian DGCA maintenance approvals, we will also be bringing the aircraft back for future maintenance work.

Duncan Aviation offers Interior Cosmetic Detailing

Posted by Diane Heiserman on Fri, Jul 26, 2013 @ 11:18 AM

Submitted by Kristi Steward, Interior Modifications/Completions Manager


S.W.A.T., in military lingo stands for “special weapons and tactics.” At Duncan Aviation, it describes a special team putting their talents to work, addressing the most-requested cosmetic details in aircraft interiors.

Frequent customer requests led Duncan Aviation to create the SWAT service to ensure that the interior of every aircraft that comes to one of our facilities—even those scheduled for only maintenance or avionics installation—leaves looking better than when it arrived; the ultimate goal being to improve your aircraft with minor interior repairs.

Every aircraft that arrives at Duncan Aviation in Lincoln, Neb., and Battle Creek, Mich., is subjected to an “Interior SWAT Team Analysis.” Offered without cost or obligation, this in-depth examination is conducted and items that can be corrected, cleaned, updated or otherwise improved to beautify the aircraft interior are identified. The inspection, combined with flight crew interviews, reveals specific areas the SWAT Team can improve while the aircraft is down. On-the-spot quotes are created and, once approved, are incorporated into the existing scheduled work without extending downtime.

Duncan Aviation holds service center authorizations for several major airframe manufacturers, including: Bombardier, Dassault, Embraer and Cessna. We are also an Organization Designation Authorization (ODA) and an FAA/EASA approved Class 1-4 airframe rated repair station. Our interior project portfolio and capabilities fact sheets are available online.

Tips and Tricks

The SWAT teams offer the following advice to keep your aircraft interior in top-notch condition:
  • Perform regular cleaning and conditioning of all leather
    and wood surfaces with approved products.
  • Avoid cleaning products that will cause a build-up and give
    surfaces a cloudy appearance.
  • Clean any inadvertent ink marks immediately with Isopropyl alcohol and a cotton swab. Once set, an ink stain cannot be removed.
  • Always cover seats when bringing luggage through the cabin.
  • Close drawers and doors softly, without slamming.
  • Perform regular interior maintenance at least every other year during service center visits.

The Hit List

The most common items addressed by the SWAT teams are: carpet cleaning, leather chair re-dye, re-webbing seat belts and cabinetry hardware adjustments.


  • Seat adjustments
  • Seat cleaning and conditioning
  • Carpet cleaning
  • Leather re-dye
  • Cabinet touch-up
  • Install new-style vinyl carpet runner
  • Install new cork in cupholders
  • Re-web seatbelts
  • Cabinet and card table adjustments


  • Instrument panel touch-up
  • Pedestal touch-up
  • Install new sun visor assembly
  • Re-web seatbelts

Other Areas

  • Replace entry step tread
  • Replace baggage step tread
  • New baggage load covers
  • Requested touch-ups
