JSSI – An Independent Voice on the Owner’s Side

• October 30, 2026

Keeping an aircraft flying depends on an entire industry of maintenance facilities, parts suppliers, manufacturers, and technicians, and most of them have their own interests to look after. So among everyone involved, who is working in yours?

In the October 2026 issue of Business Jet Traveler, Neil Book, our Chairman, President and CEO, answers with the case for independence: why JSSI was built on the owner's side in 1989, and what that puts to work for you today. More than 500 maintenance facilities, and the freedom to recommend the best one anywhere. A technical team whose engine specialists each see 40 to 60 off-wing events a year, where a director of maintenance might see five in a career. Funds held in an independent trust, earmarked for your aircraft. And a shift worth noting: roughly one in five new midsize and larger jets now enrolls with JSSI at delivery.

The point underneath all of it: when owners have a real choice, service standards rise, pricing stays competitive, and everybody wins. Read the full article on Business Jet Traveler.

The value of private aviation is freedom: your time answers to you and no one else. Everyone who keeps your aircraft flying is someone you trust: your chief pilot, your director of maintenance, your flight department or management company.

But no team controls availability alone. Keeping an aircraft in the air depends on an entire industry of maintenance facilities, parts suppliers, manufacturers, and technicians. Your people manage it all proactively, but inside a system that was not designed around you. Therefore, a question worth asking: among everyone else involved, who is working in your interest rather than their own?

Why JSSI Exists

Manufacturers set the maintenance requirements, the service network grew up around them, and no one was aligned with the operator. So, in 1989, JSSI's founders built an organization on the owners' side, offering maintenance programs coupled with deep technical expertise. Today, JSSI is the largest independent provider of maintenance support and financial tools to the business aviation industry, supporting more than 6,500 aircraft globally across its suite of solutions, over 30 percent of the world's business jets.

"If we were an airline, we would be the world's largest. At JSSI, we focus exclusively on business aviation, and advocating for our clients is at the center of everything we do. It's why we're here," says Neil Book, Chairman, President and CEO.

Built for Business Aviation

Commercial airlines fly identical aircraft thousands of hours a year on fixed schedules, backed by a robust and standardized supply chain. Business aviation is the opposite and requires a different service model: dozens of manufacturers, hundreds of makes, models, and engine types, flying on demand a few hundred hours a year. How an aircraft is flown shapes how it must be supported, and JSSI was built for this world.

Each JSSI engine technical specialist sees 40 to 60 off-wing events a year; a director of maintenance might see five in a career. Because business jets fly everywhere, JSSI is everywhere: nearly 100 technical advisors stationed around the world.

What Independence Gives You

JSSI answers to no manufacturer or maintenance facility; we answer to you. Our job is to create competitive tension to ensure you're getting the highest quality, best pricing, and most efficient turn times. Our position lets us put the entire market to work on your behalf: more than 500 maintenance facilities worldwide, from manufacturer-owned shops to independent MROs and in-house teams.

When your aircraft needs work or a part, we are free to recommend the best option anywhere, manage the event from start to finish, and make sure the work done is the work needed, at a fair price. We do not turn wrenches or compete with those who do. We are an extension of your team, working alongside your flight department or management company, never in place of them.

And your money stays yours. The funds you pay in are held in an independent trust, earmarked strictly for your aircraft's maintenance, with transparency.

What Independence Gives You

If you last evaluated JSSI years ago, you evaluated a different company. Maintenance programs remain at our core, but the capabilities around them now span the full lifecycle of ownership.

Over the past 10 years, organically and through acquisition, JSSI has expanded into 4 complementary verticals. Conklin supplies trusted, objective cost and performance benchmarking data for all business jets; JSSI Aviation Capital offers flexible asset-based financing; Traxxall is a leading maintenance tracking software solution; and JSSI Parts & Engines has become the largest independent provider of all-OEM parts and rental engines.

The value of JSSI becomes clear when it matters most: when your aircraft is down, a part is on back order, and MRO slots are full. At that point, how many options can your provider access? We are not confined to OEM inventory or shops. We can pull from our own parts inventory and rental engine pool, or leverage vendor relationships built over decades, focused on getting you flying again in days, not weeks. Your priority is ours.

Support from Day One

Some believe independent programs exist mainly to support older aircraft, while factory-new jets belong on a manufacturer's program. That is no longer true. Today, roughly one in five new midsize and larger business jets enrolls on JSSI's 100% coverage program at new aircraft delivery; on certain models, as many as one in three.

The most demanding, expensive maintenance events come with age, not in an aircraft's first years. An organization that has spent decades solving the hardest problems on in-service aircraft is, by definition, prepared to support one from its first flight hour. Enrolling at delivery means those events, most arriving after warranty coverage ends, are funded from day one, while JSSI's technical team manages warranty claims and the program covers the gaps a warranty leaves behind.

"Our reputation was built on solving hard problems: the unexpected AOG, the engine event far from home, the part no one else can find," says Francisco Zozaya, Chief Commercial Officer. "That service mindset, and the technical depth behind it, is exactly what new aircraft deserve. Enrolling at delivery is often the smart way to begin ownership: budget certainty from the first hour flown, specialists working alongside your team, and a program that supports the aircraft's value long-term."

The program also travels with the aircraft, supporting resale value. And owners who upgrade, typically every five to seven years, can even transfer accrued funds to a different model with JSSI.

Still on the Owner's Side

For most business aircraft, from engines to airframes to APUs, maintenance coverage comes down to two options: the manufacturer's program, or JSSI. Bringing JSSI into the conversation gives you the power to choose. It also keeps the market honest: service standards rise, pricing stays competitive, and every owner is better served.

Before your next acquisition, or your next program decision, ask your team to speak with JSSI. You will be better off with two options on the table, whichever you choose. Start at jetsupport.com.

For most business aircraft there are two options for maintenance coverage, JSSI or the manufacturer, and whichever you choose, you are better off with both on the table before you sign. Everybody wins when owners have a choice: service standards rise, pricing stays competitive, and the market works harder for you.

If you have a Q4 closing or a 2027 delivery on the calendar, see how the programs compare on coverage, service, and how each travels with the aircraft.
