Maintenance, Repair, and Overhaul (MRO) in Aviation Industry

Maintenance, Repair, and Overhaul (MRO) services are essential for any industry that uses machinery to run operations.
In the aviation sector, the term MRO aviation refers to all the activities that are aimed at ensuring that the aircrafts remain ready to fly at all times.
Maintenance – When work is done to ensure that the aircraft is in prime condition. There are no snags or failures observed, but the aircraft is serviced to simply keep it in functional readiness.
Repair – Aircraft often require repairs as they are complex machines with thousands of moving parts and software integrated. If an instrument panel doesn’t respond the way it should or there is a dent, an engine failure, or a broken window, repairs are carried out.
Overhaul – With a high wear and tear rate, most aircrafts undergo overhaul after a specific duration of flight operations. As a part of the overhaul process, aircrafts are dismantled piece by piece, each part inspected and reassembled.
The overhaul process allows detailed inspection of all surface and internal parts of the plane and is a key element of the aircraft’s lifecycle management and enhancement.
