Behind AEI’s success are not coincidences. It’s the people.

​

Behind AEI’s success are no coincidences. There are people. Read our interview with AEI’s Chief Operating Officer, Ľuboš Záborský, and Chief Technical Officer, Matej Pecek.

In this interview, you’ll learn:

• How Matej and Ľuboš built their careers over more than a decade at AEI.
• Why maintenance is at the heart of AEI’s success.
• Which innovations are changing aircraft maintenance today.
• How AEI handled one of the most challenging periods in aviation.
• What makes a strong team and why shared values matter.

You have both been with AEI for more than 10 years. What has your professional journey looked like from the day you joined until your current position?

Matej: I joined AEI in November 2011 as a Station Manager. It was a combined role – I was responsible for the operation of our station in Timișoara while also working as a non-certified aircraft mechanic.

When this position was being phased out, Branislav offered me a role at the head office, where I became Chief Technical Officer (CTO). Later, I joined the Bratislava Operations (BTS OPS) team while continuing to serve as CTO.

Around 2017, following several organizational changes, I moved to the Quality Department, first as Deputy Quality Manager and later as Head of Quality. In 2023, I returned to the role of CTO. This year marks my 14th year with the company. Yes, there have been many changes, but they have always happened naturally and as part of the company’s growth.

Ľuboš: I joined AEI at the end of August 2012 as a PPC Officer, working a seven-days-on, seven-days-off shift pattern.

When PPC operations transitioned to 24/7 coverage, the Bratislava Operations Department was established, and Matej and I both became part of it. Over time, my responsibilities expanded, and I eventually became Chief Operating Officer (COO). Besides overseeing operations, I gradually took on customer communication, invoicing, and contract negotiations.

Together with Matej, we’re among the company’s “old hands.” We’ve worked across most of AEI’s stations and have seen how the company has evolved from the ground up.

How would you describe the role of the Maintenance Department within AEI’s overall operations?

Matej: Maintenance is the cornerstone of our company. Without it, most of our other departments wouldn’t be needed, and many of the additional services we provide would be much more difficult to deliver.

Branislav likes to joke that 95% of all problems come from the Technical Department. But that’s perfectly understandable because the Technical Department deals with almost everything that matters – from customers to mechanics.

Ľuboš: And now, seriously. Our department’s responsibility is to ensure we have the right people, the right tools, the right materials, and the right contracts with both customers and suppliers. My role is to connect all these pieces and make sure they work together efficiently.

Which technological or process innovations in aircraft maintenance are currently the most interesting to you?

Matej: Anything that genuinely helps us move forward. When I joined the company, we relied mainly on emails and Excel spreadsheets stored in Dropbox. Over time, we introduced our own intranet and various internal systems. I believe new technologies should always deliver real efficiency and save people time.

Ľuboš: I’m particularly interested in the use of artificial intelligence for searching technical documentation. If AI can help mechanics find the right procedures faster, it makes their work much easier.

Another major topic in our industry is tool tracking, making sure every tool returns exactly where it belongs after the job is done.

Matej: We’ve also experimented with drones for aircraft damage inspections. The idea is promising, but there are still many practical challenges. As a company, we see ourselves more as implementers than developers, so we prefer adopting proven technologies and putting them into practice.

What has been the biggest challenge you’ve had to deal with?

Matej: It’s difficult to choose just one. Whatever challenge we’re facing at the moment always feels like the biggest one. But they all have one thing in common: making sure the customer is satisfied.

Ľuboš: For me, it was definitely the COVID-19 pandemic.

At that time, most of our operations were based in Romania, while the majority of our employees came from Slovakia and the Czech Republic. Travel restrictions made everything much more complicated, but the aircraft still had to remain airworthy. Some of our colleagues stayed at the base for as long as three months without rotation. Besides staffing, we also had to manage the complex logistics of transporting tools and materials.

What do you consider the key moments that have shaped your career at AEI?

Matej: Definitely my first meeting with Branislav. It was open, honest, and straightforward. Beyond that, every major challenge we’ve faced has helped me grow professionally.

Ľuboš: From the very beginning, I appreciated that the company had clearly defined values — Passion, Discipline, and Working Together — and, more importantly, that it genuinely lives by them.

What do you enjoy most about your work?

Matej: Seeing processes work better than they did before. Sometimes the improvements are small, but together they make a significant difference.

Ľuboš: I enjoy seeing things come together — signing a good contract, successfully completing a complex aircraft repair, or welcoming back a customer after some time away. Those moments are always rewarding.

What do AEI’s values mean to you personally?

Matej: They make my professional life easier. I know what’s expected of me, and I know my colleagues approach their work with the same mindset.

Ľuboš: I believe every problem has at least one solution, and our values help us find it.

In your opinion, what is the secret of a well-functioning team?

Ľuboš: Having the right people who share the same vision. If every team member is working towards a different goal, the team simply won’t succeed.

If you had to describe what AEI means to you in one sentence, what would it be?

Matej: Bringing together people who share the same values and making aviation more efficient.

Ľuboš: A strong team united by one goal: always doing more for the customer.

How AEI Earned Lufthansa’s Trust and Secured Wizz Air (Part III.)

​

Even today, a few veterans at Bratislava Airport occasionally recall how, back in 2010, they helped their boss Branislav choose a proper coat. He was heading to Germany to personally present a young Slovak company to the renowned Lufthansa Technik Maintenance International. The goal was clear: to position the company as a provider of aircraft maintenance services on the international aviation market. And for that, one must dress accordingly.

They had already established contacts with the Germans. Branislav had written to Germany several times before, offering Slovak services to the company responsible for maintaining Lufthansa aircraft worldwide. It took time, but persistence paid off. Eventually, Hamburg responded and invited him to the headquarters. He must have made an impression, as he received a surprising offer: to provide line maintenance in Romania for a young, ambitious Hungarian low-cost carrier Wizz Air.

One Introduction That Changed AEI Forever

This rapidly growing ultra-low-cost airline had already been known to Lufthansa since late 2009, as Lufthansa had been providing Wizz Air with valuable advisory support. They knew Wizz Air was preparing to open routes from Romania and needed high-quality aircraft maintenance, yet lacked the capacity to build its own demanding maintenance base. Lufthansa therefore introduced the new Bratislava-based company, Aeroengineers International (AEI), to Wizz Air. The partnership proved successful for all parties. AEI guaranteed 24/7, fast, and reliable service. A mutually beneficial three-way cooperation was born.

In August 2010, AEI opened its first line maintenance base for Wizz Air in Timișoara, Romania, followed within weeks by Cluj. Craiova, Iași, Sibiu, and Bucharest Otopeni followed. When Wizz Air launched flights from Yerevan, Armenia in 2020, gradually connecting the city to sixteen European destinations, it once again entrusted maintenance to the Slovak team.

Wizz Air had attempted to launch a route from Bratislava to Rome in 2009 but was unsuccessful. In 2015, it began operating from Košice, and the following year it returned to Bratislava. From late 2025, it has been expanding significantly there, with seventeen routes planned from the Slovak capital by spring 2026. AEI won tenders to maintain Hungarian-based Airbus aircraft, and Ryanair entrusted the maintenance of three Boeing 737 aircraft based in Bratislava to AEI- a partnership that continues today.

In 2017, Wizz Air opened operations in Chișinău, the capital of Moldova, flying to thirty-six European destinations. Slovak passengers might wonder why the airline focuses on relatively less affluent regions of Southern and Eastern Europe, while withdrawing from markets such as Abu Dhabi, certain post-Soviet countries, Vienna, the Czech Republic, and several major Western European hubs. The answer lies in the low-cost model. Unlike traditional carriers targeting wealthier clientele with business-class comfort, prime-time frequencies, hub connections, and onboard services, low-cost airlines emerged strongly after the fall of the Iron Curtain. They connected smaller regional airports, enabled labor mobility from East to West, offered affordable travel for students, and provided low-cost holiday options. They are flexible, quick to open new routes—and equally quick to close those that prove unprofitable.

Today, AEI operates at six airports across five countries. While some Romanian bases were eventually closed, a new addition to the portfolio since late 2025 is Norwich Regional Airport in the United Kingdom.

The company now employs around one hundred people. Over its fifteen-year history, AEI has employed Slovaks, Czechs, French, Hungarians, Italians, Spaniards, Croatians—even an Icelander and a Filipino living in Ireland. In Armenia and Moldova, AEI has trained and developed local personnel, meaning Slovak staff no longer need to travel there – reducing travel, accommodation, and per diem costs. These efficiencies contribute to the company’s performance. Last year, AEI reached a turnover of EUR 19 million.

Although the company primarily specializes in Boeing 737-800 Next Generation and MAX aircraft, as well as the Airbus A320 family – including the 239-seat A321neo – it also holds approval for hangar maintenance of Fokker 100 aircraft and Airbus A319 aircraft operated by the Aviation Unit of the Ministry of the Interior of the Slovak Republic, as well as their Leonardo AW189 helicopter. AEI is also authorized to maintain Embraer 170/190 aircraft and, in Bratislava, services 388-seat Airbus A330 aircraft operated by the Spanish airline World2Fly for winter charter flights to the Dominican Republic and Vietnam.

AEI continues to diversify its services strategically. It supplies airlines with certified spare parts and consumables, and together with partners, provides aircraft painting and post-maintenance weighing services. Weight control is critical in aviation – airports charge fees based on aircraft weight, and even paint selection or cabin configuration can influence overall mass. At Hradec Králové Airport in the Czech Republic, AEI established HeliBuddy, a company specializing in maintenance of Airbus Helicopters aircraft, aiming to become a strong partner for both civil and governmental helicopter operators in Central Europe.

When Good Intentions Aren’t Enough: The Turning Point That Shaped AEI  (Part II.)

​

“Robo saw an opportunity to invest, and I knew that without the right partner it wouldn’t work,” recalls Branislav Cifra, CEO and Accountable Manager of Aeroengineers International (AEI), as he reflects fifteen years later on the restart of their project. “We told ourselves we wanted to build something of our own, to work with people who put their heart into what they do, and to create an environment where quality is never a compromise and meaningful rules are respected.”

Róbert Piľa, Board of Directors & CEO, adds that they never wanted to build a “single-use company,” but something that would grow and outlive them. While military discipline is often criticised or mocked, he says they carried two essential lessons from their army years into business: the ability to work under pressure and a strong team spirit. In the military, they often substituted for specialists, and one mechanic was capable of working on multiple systems. That was standard with military aircraft types, but rather exceptional in civil aviation. This versatility later became one of their competitive advantages.

The journey was far from smooth. After just one year, the company again faced potential end. Branislav had to reflect deeply on why his first business had failed. He realised that he bore responsibility not only for the direction of the new company, but also for every failure along the way.

“Until then, I didn’t fully understand why things turned out the way they did. In both the first and the new company, we had good intentions, yet the outcomes were completely different from what we expected,” Branislav says. He came to understand that good intentions alone are not enough to lead and manage a company. A purely technical, aircraft-mechanic perspective is insufficient. Their partner Lufthansa  recognised this and raised a warning flag. Branislav was given three months to prepare a turnaround plan for the company, after which it would be decided whether cooperation with their client Wizz Air would make sense.

At AEI, they realised that technical excellence alone was not enough. Being outstanding in maintenance services must be supported by effective management and solid economic performance. Branislav began studying intensively. Among the literature he explored, he was significantly influenced by the respected American author Jim Collins. His bestseller Good to Great, published in more than three million copies worldwide, explains how a good company can become a great one.

At AEI, they agreed that passion for work, discipline to stay on course, and working together that makes individuals part of something bigger are the pillars on which to build their team. Over time, they realised that the principles on which any company should stand are relatively simple. What truly matters is implementation – an ongoing process of learning, testing, and sometimes making mistakes. Success, however, eventually follows.

Both co-owners emphasise character when selecting new colleagues. “No course can teach that. Expertise can be learned, but mindset and values cannot. That’s why we are glad to have people with different educational backgrounds on our team, united by shared values and inner alignment. That is often more important than education alone.”

Their vision is to be a reliable and respected partner in the industry – combining expertise with a human approach, heart and reason, and even a touch of playfulness. Because that, too, belongs in business.

“We would like to leave behind something meaningful – not just a ‘company,’ but a community of people who know that what they do brings value to customers, employees and society as a whole,” explains Branislav. “We want the know-how, the team, and the way of working that functions as a system creating added value to remain. We don’t want the company to disappear simply because the two of us are no longer here. Some people ask why we care about what happens after we’re gone. But if companies founded a century ago had not thought that way, their successors today would not enjoy the quality of life they do. Perhaps it sounds naïve, but we are both rather emotional people and we act according to what we believe is right.”

Last year, during AEI’s fifteenth anniversary, they were asked how they differentiate themselves from other players in the market. According to Branislav, through flexibility and persistence in overcoming challenges. “We can adapt to our customers while maintaining quality. We believe every problem has at least one solution.” Róbert adds that they do not want to be just another supplier. They want to be  and are a partner. They understand their customers and can communicate with them not only technically, but also on a human level.

They are most proud of having built, from zero, a company that now employs around one hundred people whose work satisfies clients. It is not about replacing an aircraft engine – that is simply their duty. “What truly matters is what we have contributed to our surroundings and what it has meant for the people who are part of the company and the communities where we operate. A company is like a watch – remove one gear and it stops. Fortunately, our team holds together,” say the two co-owners. Their loyalty and cohesion are reflected in the quality of their work.

Dreams, Takeoff and Restart (Part I.)

Both were born in 1977. They did not know each other at the time, yet they shared the same boyhood dream. Branislav Cifra from Trnava wanted to become a pilot. So did Róbert Piľa from Bratislava. Both studied to become aircraft technicians – Branislav at the Secondary Vocational School of Aviation Technology in Trenčín, Róbert at the Military Secondary Aviation School in Košice.

Their first shared steps came only after graduation – first during military roll calls, and later on the local football field, where they played in their spare time. Róbert was finishing his fourth year when Branislav, after completing his studies in Trenčín, came to Košice for a course that would allow him to continue in the Armed Forces of the Slovak Republic as an aircraft technician. After finishing school, Róbert was assigned to Kuchyňa Air Base near Malacky, and a few months later Branislav was deployed to the same base after completing his course. As friends and colleagues, they reunited at the Su-25 squadron, working as aircraft technicians.

However, the division of Czechoslovakia brought unexpected changes to the lives of these young men. The once-strong Slovak Air Force gradually underwent reorganisations, aircraft types were phased out, flight operations were reduced, and many skilled professionals left. Branislav’s vision of becoming a “Top Gun” faded into routine, replaced by frustration as he watched talented colleagues move into civilian life. He says the job no longer fulfilled him, so in 2003 he left the military. Róbert had left a year earlier. Branislav found work as a mechanic with a private airline, while Róbert even ventured into real estate.

The Leap into Entrepreneurship

Times were changing, though. Civil aviation was expanding and creating new opportunities. During the first decade of the new century, many new airlines emerged not only in Slovakia but also in the Czech Republic, Hungary, Poland and Romania. These carriers needed reliable partners for various services – especially technical ones. Continuous maintenance, without which safe and reliable air transport cannot exist, was essential.

Large airlines have their own maintenance teams at major airports. Smaller airports with lighter traffic, however, require flexible companies capable of serving several smaller carriers – from rapid technical checks to scheduled interventions in accordance with prescribed maintenance programmes. That is why, in Bratislava, a group of mechanics began to form around the idea of establishing a maintenance company focused on older Boeing 737 Classic aircraft as well as the newer 737 Next Generation models, which were increasingly present in Slovakia.

“The idea emerged spontaneously among people who had never done business before, had no economic or managerial education, but had a strong inner motivation to provide line maintenance in Slovakia and a vision to cooperate as effectively as possible with people who shared the same mindset,” explains Branislav Cifra about the company’s beginnings. He and a fellow aircraft mechanic stood behind the project. Their enthusiasm was so strong that, despite having secure positions at an airline that was then at its peak, they resigned. Especially as their former employer began facing financial difficulties, creating an opportunity to offer work to former colleagues. In 2008, Aeroengineers, s.r.o. was founded, employing fifteen mostly young, qualified professionals.

Although line maintenance does not require a hangar – much of the work can be performed outdoors on the apron – it still requires facilities, basic tooling, spare parts stock and operational infrastructure compliant with strict regulations. That required initial investment, which they had to secure.

They had no investor behind them and not even a preliminary agreement with a potential client. To operate commercially, they had to pass demanding international audits and so they applied. By the end of their first year, they obtained EASA PART-145 approval for maintenance of Boeing 737 jet aircraft from the European Union Aviation Safety Agency (EASA). Half a year later, they received approval for Airbus A320 aircraft as well. They then secured their first client, the Trenčín-based airline Seagle Air, which gradually expanded its fleet to include two A320-200s and four B737-300s for charter operations, primarily transporting Slovak holidaymakers to seaside destinations.

Lessons and a New Beginning

Despite a promising start, in autumn 2009 Seagle Air unexpectedly declared bankruptcy. Logically, Aeroengineers faced collapse as well. Bankruptcies of small airlines in post-communist Europe were not uncommon; owners often lacked sufficient capital and operational experience, accumulated debts, failed to pay invoices, taxes and social contributions, and frequently left employees unpaid.

Aeroengineers had to let all employees go – including friends – because there were no funds to pay them. The founders quickly realised their chances of survival were close to zero. Yet they did not give up. They searched for a new client and investor, determined to try again. At the turn of 2009 and 2010, however, their paths diverged. One of the owners left the business, but Branislav was not ready to quit. He had learned valuable lessons from the company’s collapse – among them, that in this industry, relying on a single client is too great a risk.

It is often said that success will eventually come, you simply need to be in the right place at the right time, with your eyes open. For them, that place was a shopping centre in Bratislava. Fifteen years ago, old friends Branislav Cifra and Róbert Piľa quite literally ran into each other there by chance. They sat down for coffee, reminisced, and arranged another meeting. A few days later, they agreed to try building a business together again.

And so, in 2010, they founded Aeroengineers International s.r.o. – today known as AEI^®.
