Aircraft maintenance is a fundamental pillar for ensuring air safety and the continuity of logistical and commercial operations. In El Salvador, where regional connectivity is key to economic and tourism growth, this process becomes even more relevant.
“Every maintenance intervention is a precision engineering operation. At AirSupport, we work with certified processes and high-precision equipment, because in aviation there is no room for error: safety is built piece by piece,” explained Óscar Corado, Director of Operations at AirSupport Group.
On this occasion, we want you to learn how aircraft maintenance is managed, what types of maintenance there are, and why relying on specialized companies such as AirSupport Group is a strategic decision.
What is aircraft maintenance?
Aircraft maintenance includes all activities necessary to ensure that an aircraft remains in optimal operating condition. This includes routine inspections, component repairs, technical upgrades, and compliance with national and international civil aviation regulations.
“Behind every maintenance operation is a highly trained Salvadoran team that combines experience, discipline, and a passion for aviation. They are the true guarantee that every takeoff is safe and efficient,” added Corado. “Our goal is for every aircraft that leaves our hangars to do so with the highest international standards. We earn our customers’ trust by demonstrating technical consistency and operational commitment on every flight.”
In addition to being mandatory, well-executed maintenance ensures the operational efficiency of airlines and airport logistics companies, reduces long-term costs, and enhances passenger and cargo safety.
Types and levels of maintenance
There are different types of aircraft maintenance, generally classified as follows:
- Preventive maintenance: performed at scheduled intervals to prevent failures before they occur.
- Corrective maintenance: performed when a component or system fails or deteriorates.
- Predictive maintenance: uses technologies such as sensors and data analysis to anticipate wear and tear and take action before failure occurs.
Each type is applied at different levels, from light in-line inspections to major overhauls in specialized hangars.

Key processes in aircraft maintenance
The maintenance process involves several phases:
- Initial inspection: visual and technical review of critical systems.
- Diagnosis: use of specialized tools to identify potential problems.
- Intervention: repair, replacement, or adjustment of parts.
- Operational testing: functional verification after each intervention.
- Certification: official documentation guaranteeing the airworthiness of the aircraft.
Companies such as AirSupport Group apply international standards and use state-of-the-art technology in all these stages to ensure reliable results.
