VIDEO Falcon 900: Everything and the Galley Sink

The best laid plans often go awry. Business aviation maintenance is no exception. Most maintenance directors will tell you it’s almost impossible to plan for everything that might pop up during a large inspection that is coupled with a variety of updates and upgrades.

So how can Duncan Aviation guarantee turntimes? The answer is really pretty simple but often overlooked by those who don’t have the right people and the right processes.“We plan ahead and work hard,” says Finish Team Leader Tony Houk. “We still encounter hurdles, but we work together as a team to overcome them.”

Business jets are incredible assets. When they’re in our hangars for months, we recognize the owners are missing a valuable resource, so we do our best to meet turntimes and set efficient schedules to get customers in, out and safely on their way.

When an 18-year-old Falcon 900 was added to the schedule at Duncan Aviation’s Lincoln, Nebraska, location, promising a finite out date seemed far-fetched—because it was. A laundry list of inspections, avionics, interior upgrades and new paint packed the to-do list.

During the inspection, a handful of corrosion squawks required extra hours, making serious teamwork mandatory in order to adhere to a tight schedule. With some teams needing access to the same areas at the same times, schedules were changed to second or third shifts so progressing could be maintained at the same rate.

Everyone realized they needed to make it happen, even if that meant working in hourly blocks, or changing shifts and working weekends.

And all that teamwork paid off. The aircraft delivered, the customers were ecstatic and Duncan Aviation was able to add another success story to the books.

Watch this video and witness firsthand, how all the teams (airframe, paint, interior and avionics install) accommodated each another to do what was right for our customer.

Making a 14 Year Old Falcon 900 New Again

Posted by Diane Heiserman on Tue, Jul 14, 2015 @ 08:00 AM

It was a massive amount of work completed in a short amount of time. However, it still delivered on time and squawk-free with a transformation nothing short of spectacular. 

When this Falcon 900B arrived at Duncan Aviation, the interior workscope completely changed at the last minute, allowing very little time to preplan the changes and nearly nothing for material lead time.

We think we nailed it. What do you think?

Duncan Aviation representatives are on hand to answer questions and give tours of this beautifully transformed aircraft.

Avionics Transformation

Duncan Aviation and Universal Avionics partnered to transform a Dassault Falcon 900B by installing Universal’s EFI-890 glass box cockpit. This cockpit upgrade replaced 25 older instruments, significantly improving reliability and situational awareness, and offers advanced capabilities like WAAS-LPV and FANS 1/A.

“If you want an aircraft that’s predictable to operate, properly supported and can hold its value this newly retrofitted aircraft is the way to go,” says Gary Harpster, senior avionics installation sales rep for Duncan Aviation.

Additional avionics installed include Rockwell Collin’s Venue Cabin Management System that allows passengers to watch movies on demand on high-definition displays and conduct business, seamlessly. With Collin’s new Skybox cabin sharing, passengers can securely share movies, TV shows and music wirelessly between the on-board Apple iTunes library, Apple iOS devices and the cabin displays.

Interior Transformation

In addition to the avionics installations, Duncan Aviation completed several interior upgrades, including complete soft good refurbishment, new cabinet veneer, Duncan Design Collection PSU overlay panels, EMTEQ LED lighting and much more.

You still have time to visit and walk through this Falcon 900B today and Thursday. The aircraft is currently at NBAA static display #140 at the Henderson Executive Airport in Las Vegas, Nevada. Gary Harpster and Duncan Aviation’s Avionics Tech Rep, Chris Christenson, will be on-site for a personal tour and demonstration.

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

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

Submitted by Gary Harpster, senior avionics installation sales rep

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

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

Universal EFI-890

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

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

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

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

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

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

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

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

How weak is that link now?

Duncan Aviation Custom Solution for Dassault Falcon Lav, Storage Swap

Posted by Diane Heiserman on Fri, Aug 02, 2013 @ 11:12 AM

Falcon Lav

Duncan Aviation’s design and engineering teams collaborated to craft a custom cabinet to replace the forward lavatory in Falcon aircraft so customers could choose from a variety of dedicated storage options or a preparation station instead of struggling to utilize it as a provisional closet.

Interior engineers often need to think outside the box to come up with one-of-a-kind solutions for customers, and one of those solutions—a forward lavatory conversion to a storage space in two Dassault Falcon models—has caught on among Duncan Aviation customers.

A portion of Falcon 900 and 2000 aircraft have two lavatories. In those aircraft, the front lavatory often remains unused for its intended purpose and is transformed into a makeshift storage compartment. Duncan Aviation’s design and engineering teams collaborated to craft a custom cabinet to replace the forward lavatory in both Falcon aircraft so customers could choose from a variety of dedicated storage options or a preparation station instead of struggling to utilize it as a provisional closet.

“The problem is a lot like your closet at home. If you just stack and throw things in there, an avalanche of belongings is always looming,” says Jeff Beaudette, engineering team leader.

The collaboration resulted in a cabinet solution that completely replaced the lavatory while retaining the plumbing. Duncan Aviation has modified three aircraft since creating the solution.  

“We capped all the lines from the toilet and built a cabinet insert that molded around the old chute just in case the next owner wanted to reinstate the lavatory,” says Steve Rosenow, cabinet team leader.

The lavatory is nestled between the galley and the jump seat, and the space is anything but standard.

Steve says the initial Falcon 900 customer requested a large ice drawer in the bottom and a coat closet up top, but the space looks a bit like a soda bottle, so it took a bit of finagling to ensure they utilized every square inch.

“Customers just want the option—the opportunity to define that space when they sell the aircraft or if their needs change while they own the aircraft,” says Rosenow. “And that’s what we’re here to do. We create a custom solution that affords them countless options.”

As for the Falcon 2000, the modification was very similar to the previous 900 storage swap.

Duncan Aviation provided a cooled catering box storage, crew closet, upper storage and a lower drawer. The storage conversion was done in addition to a partial paint, left-hand forward crew closet modification, left-hand entertainment cabinet modification, removal of tray storage, removal of a microwave and the addition of a passenger coat closet.

Duncan Aviation will accommodate almost all requests and provides customers versatility in both design as well as engineering. The company requesting the modification owns another Falcon 2000 with significantly more storage and preferred those capabilities.

“All three of the modifications we completed are similar, but differ greatly in their final function. There is no such thing as a standard part or design. Many items may be very similar, but the customization for the customer is the key,” says Beaudette.

Duncan Aviation's custom interiors have come to be admired around the world not only for their beauty but also for their innovative style and durability. View Duncan Aviation's interior galleries here

Falcon: Special Commercial Program for F900EX S-Duct

Posted by Diane Heiserman on Fri, Jun 21, 2013 @ 12:12 PM

Contributed by Kevin Bornhorst, Airframe Tech Rep.

FSA900EX-54-10-02-R5

Dassault issued Falcon Service Advisory FSA900EX-54-10-02-R5 in 2009 after receiving reports from F900EX operators about a brown discoloration and in some cases a distortion of sections of the S-duct inner skin.

The suspected cause of the discoloration is the overheating of the S-duct due to sustained use of the anti-ice power in cruise above 30,000 feet. Dassault has issued the AFM Temporary Change No. 61 that modifies procedures regarding the use of the override mode for engine #2 and wing anti-ice. They also added a check of the rivet condition inside the S-duct to the basic inspection

The distortion of the inner skins of the S-duct was determined to be an overpressure due to an excessively open HP valve, combined with a high N1 setting. Dassault has modified the design of Section #1 of the S-Duct to correct the distortion. Since the introduction of this redesign, the number of distortion reports has significantly reduced. 

Special Commercial Program

I want to remind Falcon 900EX operators that Dassault Falcon has a Special Commercial Program for the Falcon Service Advisory FSA900EX-54-10-02-R5 that extends the warranty on materials and provides a discount program for parts if exchanged prior to failure.

Restrictions

This program is for F900EX S-duct Sections 1, 2 and 3 that are made of 2024 aluminum alloy and is limited only to the correction of the discoloration and distortion issues discussed above.

Warranty

  • Material warranty is extended from five to 10 years.
  • Labor warranty is extended from six months to 3 years.
  • No repair will be done on a part under warranty. Any section with cracks will be systematically exchanged with a new part.

Exchange

  • If your F900EX is six year old or less, you will get a 50% discount off the regular new part price.
  • If your F900EX is 12 years old or less, you will get a 25% discount off the regular new part price.

If you have any questions about this FSA, don’t hesitate to ask me or any of the other Duncan Aviation Falcon Tech Reps.

Falcon Aircraft Fuel Tank Management

Posted by Diane Heiserman on Wed, Apr 03, 2013 @ 08:00 AM

Contributed by Ron Grose, Airframe Tech Rep

There are two facts operators should be aware of when it comes to fuel:

contaminated fuel filter

Example of a contaminated fuel filter due to microbial growth.

  1. All hydrocarbon fuels have micro-organisms that live and grow in them and these bugs release sulphur-based by-products into the fuel.
  2. All hydrocarbon fuels have water in them which, when combined with the sulphur-based by-products, release sulphuric acid into the fuel.

To help eliminate the damage which can be inflicted into the fuel tanks by these bugs, operators need to perform a couple simple processes. 1) Sump the fuel tanks on a regular basis, weekly if necessary, to remove the water and debris left from the bugs and; 2) Perform the “Fuel Contamination Detection Test” (MP 28-00-00-280-801) at every “A” inspection or more often if needed, such as in a tropical environment.

If the “Fuel Contamination Detection Test” detects a high concentration of microbiological contamination, or if the operator suspects receiving a contaminated load of fuel, Dassault recommends treatment of the fuel with Biobor JF or Kathon FP 1.5 as directed by MP 28-00-00-910-803: “Treatment of Fuel System Contamination.” Dassault has revised this procedure by eliminating the “preventative treatment” option of these biocides. They only recommend the full “lethal dosage” treatment as directed by the MP.

Note: Fuel anti-icing products, such as Prist, are known to slow the development of micro-organisms but do not eliminate these bugs. This is the reason to use Biobor or Kathon only.

During the accomplishment of the “C” inspection, we recommend the removal of all of the fuel tank sump drain valves to inspect for corrosion of the valves/mating surface along with replacement of the seals in these drain valves. Since the fuel quantity probes are removed during this inspection, to perform the borescope inspection of the fuel tanks, this is a good time to inspect the probes and wire connections to them to ensure the connections are clean and installed properly to prevent future fuel quantity indication issues. Even though Dassault does not have a requirement to perform a calibration check of the fuel quantity system, Duncan Aviation recommends performing a capacitance, insulation, and calibration check at this inspection to ensure the quantity indication system is properly calibrated.

These recommendations will help operators maintain the fuel tanks correctly to eliminate costly repairs along with fuel quantity issues in the future.

Avoid Escalating Aircraft Maintenance Fees with Firm Fixed Pricing

Posted by Diane Heiserman on Tue, May 08, 2012 @ 06:00 AM

Contributed by Dale Hawkins, airframe service sales rep.

Business Aircraft Maintenance

Business aircraft budgets are tight. Firm Fixed Pricing gives more control over maintenance expenses.

When it comes to business aircraft maintenance costs, most operators are able to effectively budget what they want to spend on interior, paint, and avionics. But when it comes to airframe maintenance, there are many unknowns. Even a well-educated guess can still result in the Director of Maintenance (DOM) having to explain why the aircraft maintenance costs came in higher than expected. Firm Fixed Pricing offers business aviation customers a guaranteed labor price for scheduled inspection packages, giving more control over maintenance expenses.

How does Firm-Fix Pricing work?  

An MRO offering Firm Fixed Pricing agrees to perform scheduled inspections and all discrepancies noted as a result of these inspections at a predetermined fixed price. The price includes the inspection labor (often called flat rate), miscellaneous parts needed for the inspection, labor for discrepancies noted as a result of the inspection (unknowns) and all consumables. Due to continuous price fluctuations, major parts or outside vendor services are not included in Firm Fixed Pricing.

With all the unknowns, how is an MRO able to offer Firm Fixed Pricing?

Knowledge and experience is the only way a qualified MRO is able to offer Firm Fixed Pricing. Through years of performing the same airframe inspections over and over, innovations are discovered, efficiencies are gained and valuable historical data is collected; reducing the risk of a guaranteed labor rate.

Why aren’t more MROs offering Firm Fixed Pricing?

Simply put, the potential risk of losing profit margins is just too high. The majority of the reluctance stems from the unknown possibility of discovering major corrosion damage during an airframe inspection. A discovery of this type is not uncommon and can escalate the cost and extend the downtime of any airframe inspection.

Minor airframe corrosion is covered under the Firm Fixed Pricing program and corrosion that requires Engineering Services from the OEM are offered at an exceptionally discounted rate.

Firm Fixed Pricing for Falcon Airframe

Duncan Aviation has been offering Firm Fixed Pricing on Falcon airframes for six years. Since then many Duncan Aviation customers have taken advantage of the guaranteed labor rate. Here’s what a few have had to say.

Ken Peartree, Hewlett Packard DOM — “No other company was willing to use such a creative approach. It was great for us!"

Joe Sasser, DOM — "I challenged Duncan Aviation to create this program as I believe the industry is moving that direction. We performed two separate C inspections on our Falcon 50 and 900EX. We were very pleased with the team's performance and our accounting department loved knowing where we stood before performing the work."

Chuck Baker, Greenleaf DOM— "I have maintained this aircraft for many years, but never been to this level of an inspection. I really don't know what will be found. I do suspect there will be some S-duct cracking and possibly some tank corrosion. Given that, we believe Duncan's Firm Fixed is the way to go!”

Bottom line for us is simple. Duncan Aviation has a tremendous amount of history and expertise with all Dassault airframes that we are willing to take the risk for our customers.

Our relationships with our customers are very important to us. We continually look for ways to enhance and improve their Duncan Aviation experience and are challenging our other teams to pursue offers of Firm Fixed Pricing for other airframe types. Stay tuned.

Let's Talk Firm Fixed Pricing at EBACE

Dale is attending European Business Aviation Convention and Exhibition (EBACE) in Geneva, Switzerland, May 14 – 16. If you have any questions or want to talk about Firm Fixed Pricing for you next Falcon inspection, schedule an appointment with Dale or stop by Duncan Aviation’s stand #456.
