MRO services must be supplied at airports and, on occasion, at specified off-airport locations, depending on the type of service required.
Fremont, CA: MRO (Maintenance, Repair, and Overhaul) services are critical for any sector that relies on machinery. MRO aviation refers to all actions in the aviation industry that strive to keep aircraft ready to fly at all times.
Airports across the world have many types of MRO aviation services on-site. Generally, maintenance work is performed on the plane's airframe or engines. Nonetheless, MRO aviation activities increasingly encompass component MRO. MRO services must be supplied at airports and, on occasion, at specified off-airport locations, depending on the type of service required.

For example, routine in-service examinations, daily update actions, and regular troubleshooting can be performed while the aircraft is parked at the airport. If avionics, radios, or other detachable equipment need repair, they can all be removed from airplanes and hauled away for MRO services. MRO activities are classified into three types:
- Maintenance
When it's time to keep the aircraft in good condition, there aren't any snags or problems, yet the aircraft is repaired to keep it operationally ready.
- Repair
Because aircraft are sophisticated devices with thousands of moving parts and software incorporated, they frequently require maintenance. Repairs are performed if an instrument panel does not respond as it should or if there is a dent, engine failure, or a damaged window.
- Overhaul
Because of the high rate of wear and tear, most aircraft require an overhaul after a certain period of flying operations. Aircraft is dismantled piece by piece throughout the overhaul process, with each item examined and reinstalled. The overhaul procedure provides for extensive inspection of all surface & interior plane elements and is a critical component of aircraft lifetime management and enhancement.
There are numerous types of MRO facilities in use today. Here are several examples:
- Fixed-Base Operators (FBOs)
FBOs are located at airports and provide services including aircraft refueling & parking for both resident & transient aircraft. Leading FBOs have MRO aviation facilities built in.
- Commercial Airline Hubs
All airlines strive to maximize fleet utilization. That is why many airlines run their own MRO sections to assist them in maintaining their aircraft in a more timely and cost-effective manner.
- Regional Airline Maintenance
MRO approaches differ for smaller or regional airlines. They have smaller fleets, fewer flights, and poorer profit margins than national and international airlines. Some airlines operate smaller and more dispersed MRO operations. Instead of constructing their hubs, they frequently lease space from FBOs at large airports.
- Corporate flight operators
The top corporate air operators also construct their respective MRO facilities. Generally, they will have a staff of qualified mechanics working just on their planes.
