As the aviation industry continues to evolve, reliability, efficiency, and sustainability have become critical factors for airlines and operators worldwide. EPCOR BV, conveniently located at Amsterdam Airport Schiphol in The Netherlands, stands at the forefront of these developments. As a wholly owned subsidiary of KLM Royal Dutch Airlines and being part of Air France Industries KLM Engineering & Maintenance, EPCOR offers a comprehensive suite of maintenance solutions, leveraging a modern, state-of-the-art facility and a workforce of more than 200 highly skilled professionals. The company’s mission is to be the number one MRO partner for flexible maintenance solutions.
World-Class APU Maintenance, Repair, and Overhaul
Auxiliary Power Units (APUs) are essential components that ensure aircraft systems function reliably on the ground and during flight. At EPCOR, we specialise in the maintenance, repair, and overhaul (MRO) of a broad range of APUs including:
- GTCP131-9A for Airbus A320 family                  •    APS2300 for Embraer 175/195                                                                          Â
- GTCP131-9B for Boeing 737 family                    •    APS5000 for Boeing 787
- GTCP131-9C for Airbus A220                                •    HGT1700 for Airbus A350
- GTCP331-350(C) for Airbus A330/340
- GTCP331-500 for Boeing 777
Our ultra-modern workshop of 10,000 m² is equipped with advanced diagnostic, measurement, and testing facilities, enabling us to carry out efficient and rapid overhaul and maintenance processes without compromising on technical quality and reliability.
Our APU MRO services are designed to maximize operational reliability and minimise downtime. We offer comprehensive inspection, repair, and overhaul programmes tailored to the unique requirements of each customer. With a dedicated team of experienced engineers, EPCOR is able to ensure that every unit leaving our facility meets the highest international safety and performance standards.
Powering the Future with the HGT1700 APU for the Airbus A350
EPCOR has taken a major step in aerospace innovation by adding the HGT1700 APU for the Airbus A350 to its maintenance portfolio. As one of only two MRO shops worldwide licensed to service this advanced unit, EPCOR is able to demonstrate its technical leadership and strategic foresight. The HGT1700 offers enhanced efficiency, lower emissions, and high reliability—aligning with the industry’s push for sustainability and performance. This expansion not only strengthens EPCOR’s market position but also reinforces its role as a trusted partner for next-generation aircraft support.
The HGT1700 is derived from the GTCP331-500 APU, a model with which EPCOR has over 15 years of experience in maintenance. This longstanding expertise provided a solid foundation for EPCOR to obtain its license for the HGT1700 and underscores the OEM’s confidence in EPCOR’s technical capabilities.
Comprehensive Component Repair Capabilities
Beyond APU expertise, EPCOR is an important provider of (pneumatic) component repair. Pneumatic systems are critical for vital aircraft functions such as air conditioning and pressurisation. Our in-house capabilities cover the repair and overhaul of air cycle machines, starters, valves, pressure regulators, and other essential components. By managing the entire process within our facility, we deliver shorter lead times, consistent quality, and cost-effective solutions for our clients.
Our component services are supported by a highly skilled workforce and the latest repair technologies. We are committed to keeping the fleet of our customers efficient, safe, and ready for operation at all times.
Asset Management
Understanding the operational challenges faced by airlines, EPCOR provides a comprehensive range of APU lease opportunities designed to support the operational needs of airlines and aircraft operators worldwide. With a strong and significant inventory of owned APUs, we can offer both short-term and long-term lease or exchange options. This flexibility ensures that our clients always have access to the right auxiliary power unit solution, whether they require a temporary replacement during maintenance or a longer-term lease to optimise the operational performance of their fleet.
By making these APUs readily available, EPCOR helps minimise aircraft downtime and keeps the operations of our customers running smoothly. Our experienced team works closely with customers to understand their specific requirements and deliver tailored leasing solutions that maximise efficiency and reliability. With EPCOR as your partner, you can count on immediate access to high-quality APUs, ensuring your aircraft stay in service and your business remains agile in a dynamic aviation environment.
Driving Innovation: Advanced Maintenance Technologies
EPCOR is dedicated to driving innovation in aviation maintenance through advanced technologies. Our use of Fluorescent Penetrant Inspection (FPI) ensures precise detection of even the smallest surface defects, enhancing safety and reliability. The introduction of 3-D-scanning technology enables accurate measurement and assessment of components, streamlining inspection and repair processes. Additionally, EPCOR is investigating how to apply Cold Spray technology, allowing for efficient, low-heat metal repairs that extend component life. These innovative solutions help reduce turnaround times and maintenance costs that will deliver exceptional value to our customers.
PROGNOS® for APU: Data-Driven Predictive Maintenance
At EPCOR, innovation is at the core of our business. We offer PROGNOS® for APU, a cutting-edge predictive maintenance platform that harnesses real-time operational data to forecast potential issues before they arise. With PROGNOS® for APU, airlines gain valuable insights into the health of their APUs, enabling condition-based maintenance scheduling, minimising unplanned downtime, and optimising the lifecycle of critical assets. This data-driven approach not only saves costs but also enhances safety and fleet reliability.
