Out of Phase Maintenance refers to inspections and repairs that occur outside the regular scheduled maintenance activities set in the Maintenance Programme. These checks are essential for ensuring aircraft safety and performance. Typically, this type of maintenance includes precautionary inspections of components or systems at specified intervals based on completed flight cycles or elapsed flight hours. It’s important to note that Out of Phase Maintenance is carefully documented and controlled through the Aircraft Technical Log. This process helps maintain clear records and ensures compliance with safety regulations.
