Aircraft maintenance refers to the routine checks and repairs performed on airplanes to ensure they operate safely and efficiently. 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 catch issues before they become serious, and corrective maintenance, which addresses problems after they occur. Skilled professionals, known as aircraft maintenance technicians, perform these tasks, following strict guidelines to maintain the aircraft's airworthiness and safety.
