Aircraft APU Exchange vs. Overhaul: Which Solution Is Right?

When an aircraft’s Auxiliary Power Unit (APU) requires maintenance, one of the first decisions operators face is whether to choose an APU exchange or complete an APU overhaul. The right solution depends on your operational goals, aircraft downtime, and maintenance schedule.

An APU exchange program allows you to replace your unit with a serviceable APU while your original unit is repaired or overhauled. For operators looking to minimize downtime, this can be the fastest path back to service.

An APU overhaul, on the other hand, restores your existing unit through inspection, repair, replacement of worn components, testing, and certification. Overhauls are often the preferred option when maintaining the long-term value of an owned asset.

At TAG, we support both options. Our in-house MRO capabilities, available inventory, and exchange programs allow us to recommend the solution that best fits your operation, not just the one that’s available.
