Aircraft maintenance refers to the routine checks and repairs performed on airplanes to ensure they are safe and operational. This process includes inspections, servicing, and replacing parts as needed. Maintenance is crucial for preventing mechanical failures and ensuring compliance with aviation regulations. There are different types of maintenance, such as preventive maintenance, which aims to identify and fix issues before they become serious, and corrective maintenance, which addresses problems after they occur. Skilled professionals, known as aviation maintenance technicians, carry out these tasks to keep aircraft in top condition for safe flights.
