• Adaptive maintenance: Upgrading and adding new capability, such as an in-flight movie system or a more powerful radar system.
• Perfective maintenance: Improving engine efficiency, reducing fuel consumption rates, or increasing intervals between scheduled maintenance.
• Preventive maintenance: Developing maintenance procedures that will avoid future problems. Examples might include inspecting and tightening fasteners, checking lubricant levels, and examining hard-to-reach areas to determine whether or not corrosion has occurred.
