Do you track maintenance events or engine overhaul events?

No, Fleets Analyzer does not record historical maintenance or engine overhaul events and we do not track shop visit recommended intervals (i.e the equivalent for airframe maintenance) or are we able to track the history of the shop visit for a specific engine. One reason being it is not possible to identify which specific engine serial number is attached to which aircraft at a point in time. Engines will often be moved around a fleet or swapped in and out of engine lease pools.

However, the Aircraft - Projection tab can project future airframe maintenance checks for commercial jets.
