AMAC Aerospace Completes Maintenance on Bombardier Jets in Basel
AMAC Aerospace finished maintenance and refurbishment projects on five Bombardier business jets, combining inspections with upgrades to minimize downtime.
This article is based on an official press release from AMAC Aerospace.
On May 8, 2026, AMAC Aerospace, the world’s largest privately owned Maintenance, Repair, and Overhaul (MRO) and Completion center, announced the successful completion of several maintenance and refurbishment projects on a fleet of Bombardier business jets. The work, conducted at the company’s headquarters in Basel, Switzerland, underscores a growing industry strategy where operators combine mandatory calendar-based maintenance with interior and exterior upgrades.
According to the official press release, the recent projects involved five distinct Bombardier aircraft and were completed in early 2026. As business aviation continues to experience robust demand, MRO facilities are seeing their schedules fill up rapidly. AMAC Aerospace has reported that its maintenance slots are currently booked well into mid-2026, reflecting a highly active sector.
Recent Bombardier Maintenance and Refurbishment Projects
Global Express and Global 5000 Overhauls
The company detailed extensive work on two of Bombardier’s ultra-long-range jets. A Bombardier Global Express arrived at the Basel facility on a short-notice, drop-in basis for due maintenance. During this visit, the AMAC team performed an ultrasonic inspection of the engine’s low-pressure (LP) compressor disc. Additionally, the press release noted that technicians successfully rectified a cabin noise issue that had been reported by the long-term customer.
Simultaneously, a Bombardier Global 5000 underwent a scheduled 15-month inspection, which is a standard regulatory requirement for the airframe. According to AMAC Aerospace, this project included both interior and exterior enhancements. Technicians replaced the cabin countertops, as well as the aircraft’s windshield and nose cone. The new nose cone was custom-painted to seamlessly match the fuselage’s existing lines and colors.
Challenger 604 and 605 Inspections
In the heavy-class corporate jet category, AMAC Aerospace completed work on three Challenger series aircraft. A Bombardier Challenger 604 underwent standard 12-month and 24-month calendar inspections. Routine maintenance for the Challenger 600 series is rigorous, with industry data indicating that annual maintenance costs for a Challenger 604 or 605 typically range between $650,000 and $900,000, depending on utilization.
Two Bombardier Challenger 605 aircraft were also serviced. The first completed a standard 12-month inspection. The second Challenger 605 underwent a 24-month inspection combined with a comprehensive cabin refurbishment. According to the company’s statement, the interior upgrades featured the installation of new carpets alongside new leather covers for the seats and divan, illustrating the trend of maximizing downtime efficiency.
Industry Trends Driving MRO Demand
The “One-Stop-Shop” Approach
Aircraft downtime represents a significant cost for private owners and charter operators. To mitigate this, a major trend in business aviation is the “one-stop-shop” efficiency model. Operators are increasingly combining mandatory maintenance checks with cosmetic or avionics upgrades. AMAC Aerospace utilizes this business model to allow maintenance, refurbishment, and modifications to occur simultaneously, thereby reducing overall ground time.
“The industry is currently facing longer lead times for materials from vendors due to high worldwide demand.”
Following this observation, Kurz urged operators to plan their maintenance downtime and secure hangar slots months in advance to avoid operational disruptions.
AirPro News analysis
We observe that the aging fleets of early Global Express models and Challenger 604s, which were produced until 2006, are driving a significant portion of this refurbishment market. While these airframes remain highly viable and structurally sound, their interiors and technology often require modernization to meet current executive standards.
Instead of purchasing new aircraft, which can easily exceed $50 million, many owners are opting to heavily refurbish the interiors of their existing jets during heavy maintenance checks. Furthermore, with Bombardier’s introduction of the “Evolved Maintenance Intervals” program for the 604/605, which lengthens the time between certain inspections, accurate logbook tracking and strategic planning with MROs have become highly critical for operators looking to maximize their assets.
Frequently Asked Questions
What is AMAC Aerospace?
Founded in 2007, AMAC Aerospace is the largest privately owned MRO and Completion center in the world. Headquartered in Basel, Switzerland, the company employs nearly 1,000 people globally and is an approved center for major OEMs including Airbus, Boeing, Bombardier, Dassault, and Gulfstream.
Why are operators combining maintenance with refurbishments?
Aircraft downtime is costly. By combining mandatory calendar-based inspections (such as 12-month or 24-month checks) with interior refurbishments or component replacements, operators can minimize the total time their aircraft is grounded and out of service.
