Aircraft APU Overhaul and Repair: A Market Overview

Auxiliary power units are critical aircraft systems that provide electrical power and pneumatic air for engine start, cabin climate control, and ground operations. The global APU aftermarket — encompassing overhaul, repair, and component exchange — represents the largest segment of the aircraft APU market, accounting for roughly 65% of total APU spending.

OEM vs. Independent Repair Channels

Airlines and lessors face a strategic choice between OEM-exclusive repair networks and independent Part 145 shops. OEMs such as Honeywell control approximately half the APU MRO market through proprietary repair data and authorized service agreements. Independent shops — including specialists like TurbineAero, Revima, and EPCOR — compete on turnaround time, pricing flexibility, and multi-platform coverage. Many independent providers hold direct OEM authorizations, blurring the traditional OEM-vs-independent divide.

Certification and Compliance

APU repair stations must hold applicable regulatory approvals for their operating region:

FAA Part 145
Required for operators under U.S. registry. The FAA maintains a searchable database of all certified repair stations.
EASA Part 145
Required for EU-registered aircraft. Mutual recognition agreements with the FAA simplify dual certification.
CAAC / Other National Authorities
Operators in China, India, and other markets require additional national approvals.

Selection Criteria for MRO Planners

When sourcing APU repair capability, key evaluation factors include: certified scope of work for specific APU models, guaranteed turnaround times (critical for AOG situations), availability of serviceable exchange units, OEM authorization level, and geographic proximity to minimize logistics costs and time.

Frequently Asked Questions

Q.What APU models are covered in this database?

The database covers all major commercial APU platforms including the Honeywell GTCP131 series (A320, 737), GTCP331 series (767, 777, 747), Pratt & Whitney Canada APS3200 and APS5000, as well as regional and business jet APUs like the GTCP36 and TSCP700.

Q.How is the certification data verified?

Certification data is collected from publicly available regulatory databases including the FAA repair station directory and EASA approval listings. When you request the data, our AI crawls these sources in real time to deliver the most current approval status.

Q.Can I filter by shops authorized for AOG support?

Yes. You can specify AOG response capability as a filter condition. Many listed shops offer 24/7 AOG desks with expedited turnaround times, and the dataset captures this capability where publicly disclosed.

Q.Does the list include OEM-authorized independent shops?

Yes. The database includes both OEM-operated service centers and independent Part 145 repair stations. Where publicly available, OEM authorization status (e.g., Honeywell Channel Partner) is captured as a data field.

Q.What regions are covered?

The database covers APU repair stations globally, with concentrations in North America, Europe, and Asia-Pacific — the three largest MRO markets. Coverage extends to the Middle East, Latin America, and Africa where certified facilities exist.
