Remaking A Gulfstream IV-SP Corporate Shuttle


Duncan Aviation recently worked with a longtime customer to refurbish a Gulfstream IV-SP to better operate as a corporate shuttle for up to 14 passengers.

This longtime Duncan Aviation client uses a fleet of GIV-SPs that operate as vital corporate shuttles, often flying 12-to-14 people on long international trips, says Austin Chambers, Airframe Service Sales Rep for Duncan Aviation. One of their aircraft had a 96-month inspection due, which required that the interior be removed and replaced. It sported a configuration that did not have divans designed for their mission requirements, nor were they the client’s preferred seating option for three adults. Duncan Aviation and the customer decided an extensive cabin reconfiguration along with the inspection was the best option for the aircraft’s mission.

“This was a great opportunity to show what Duncan Aviation can do, offering something truly custom for a client’s specific needs. Whenever we get the opportunity to work large, multi-shop projects like this, it’s exciting. This is where Duncan Aviation really shines,” Austin says.

Meeting Interior Needs

The interior design was lead by Kristen Cotugno, Senior Lead Designer with Duncan Aviation in Battle Creek. Kristen knew she was up to a unique challenge after listening to the customer’s needs. She concluded that the interior needed to be durable enough to hold up to constant use while displaying subtle masculine features and providing comfort to all 14 passengers. She and our internal design team got to work with the support of Duncan Aviation’s engineering department and built renderings to review with the customer.


The Gulfstream GIV-SP delivered earlier this year with a completely refurbished and reconfigured interior featuring 14 individual cabin seats in walnut brown leather. The unique configuration has all of the seats facing straight ahead toward the cockpit, similar to typical airline seating. Many of the seats feature rotating bases, allowing them to pivot 180 degrees when needed, which gives the seats the flexibility to function more like seats do in a standard corporate configuration. In the end, countless hours of planning and execution all came together for a truly beautiful and versatile finished product and another satisfied customer.

“Our clients had specific mission requirements and although what they were asking us to complete was difficult, we embraced the challenge and delivered a product that substantially surpassed their expectations, all while staying within their budget,” says George Bajo, Completions and Modifications Manager.

Other Completed Work

In addition to the inspection and the refurbishment, the aircraft’s workscope included a 5000 landing inspection, including replacement of the failed cap angle, and a full custom paint scheme. The company’s other two GIV-SPs also came in for heavy airframe maintenance events, full paint refurbishments, 5000 landing inspections and cap angle replacements.
