Why is component repair important in the aviation aftermarket?

Component repair is central to the aviation Maintenance, Repair, and Overhaul (MRO) ecosystem. It allows airlines and MRO providers to reduce costs, extend component lifespan, and ensure continuous fleet availability.

In the aviation aftermarket, component repair:

Restores functionality and airworthiness at a fraction of the replacement cost
Reduces lead times compared to sourcing new OEM parts
Minimises waste by supporting sustainability and circular economy goals
Keeps aircraft downtime to a minimum during scheduled maintenance
Ensures compliance with OEM, FAA, and EASA standards

Satair supports airlines and MROs through our global Component Repair Services, connecting operators with certified repair shops and managing the entire process — from logistics to certification.

The component repair process in aviation

Each repair step follows approved procedures defined in the CMM (Component Maintenance Manual) or OEM repair data to ensure full traceability and regulatory compliance.

Stage	Description	Example activities
1. Inspection & evaluation	The component is visually inspected and tested to identify defects or damage.	Non-destructive testing, functional checks
2. Disassembly	The part is dismantled for internal inspection and cleaning.	Separation of subassemblies, contamination removal
3. Repair or overhaul	Defective parts are repaired, replaced, or reconditioned.	Machining, welding, seal replacement
4. Reassembly & testing	The component is reassembled and tested against OEM specifications.	Pressure testing, calibration, performance checks
5. Certification & return	Documentation is issued to confirm airworthiness.	FAA Form 8130-3 or EASA Form 1 release

How is component repair managed in aviation operations?

Airlines and MRO providers manage component repairs through dedicated repair management systems, which track part status, history, and turnaround times.

Common approaches include:

Repair-by-the-hour (RBTH) programmes for predictable cost planning
Repair management services coordinated by suppliers like Satair
Rotable exchange programmes to maintain aircraft availability
Digital tracking for serial numbers, certificates, and repair cycles

Efficient component repair management helps airlines reduce total cost of ownership while ensuring reliability and compliance.
