The main objectives of aircraft maintenance are to avert accidents stemming from mechanical issues, prolong the aircraft’s operational life, and meet regulatory standards.

Types of Aircraft Maintenance

Aircraft maintenance is undoubtedly a crucial aspect of the aviation industry. Currently, there are two primary types of aerospace maintenance: line maintenance and base maintenance. Let’s take a closer look:

Line Maintenance

Line maintenance is the first line of defense in aviation maintenance and is often performed daily. It includes routine checks, minor maintenance and repairs, and inspections carried out before or after each flight. Line maintenance ensures that aircraft engines are in optimal condition for their next journey and addresses any issues that may have arisen during the previous flight.

Base Maintenance

In contrast to line maintenance, base maintenance is more extensive and typically occurs at predetermined intervals or milestones in the aircraft’s operational life. This type of maintenance involves more complex tasks, such as major repairs, structural inspections, and component replacements. Base maintenance is often conducted in a dedicated maintenance facility, where the aircraft undergoes a more thorough examination and servicing.

Understanding the types of aircraft maintenance is vital to ensuring safety, preventive maintenance, and regulatory compliance. It also makes the process easier to avoid future inconveniences and damages.

Key Components of Aircraft Maintenance
