What are the two main types of maintenance in military aviation?

The two main types of maintenance in military aviation are rework and upkeep. Rework refers to the extensive work required to restore an aircraft or its components to a specific condition, often involving significant repairs or modifications. This is usually done on a scheduled basis or when certain conditions are met, such as following operational use or after an inspection reveals issues.

On the other hand, upkeep includes the routine and preventive maintenance performed to ensure that an aircraft remains in a safe and operational state. This type of maintenance is performed regularly and includes tasks like inspections, lubrication, and minor repairs to prevent larger problems.

Together, rework and upkeep encompass the full spectrum of maintenance activities necessary for maintaining the readiness and safety of military aircraft. This understanding is crucial for ensuring compliance with military standards and operational effectiveness.
