Overhaul Considerations
To determine the maintenance intervals, use fuel consumption, service hours, or calendar time, whichever occurs first . Experience has shown that maintenance intervals are most accurately scheduled on the basis of fuel consumption.
Before each consecutive interval is performed, all of the maintenance items from the previous interval must also be performed.
