THE TRUTH ABOUT MAINTENANCE PROGRAM BUY-IN FOR OVERHAULED ENGINES

If you buy an aircraft with freshly overhauled engines, does it mean there will be zero buy-in for a maintenance program? It depends. Our expert has the details.

THE SIGNIFICANCE OF LIFE-LIMITED PARTS

In aircraft transactions involving recently overhauled engines, both the buyer and seller may assume that there will be no cost for buy-in to an engine maintenance plan. However, depending on the coverage level held by the previous owner or if the engine was not on a program, it may not always be the case.

“A potential situation involves a buyer who purchases a mid-size business jet with mid to high total time on the airframe and freshly overhauled engines,” says Delray Dobbins, Senior Manager, ESP Sales, P&WC. “Once the transaction is complete, the buyer initiates enrollment in a full-coverage maintenance program—only to be told there will be a significant buy-in. Understandably, the outcome is an unhappy new owner.”

The takeaway here is if you are buying, selling or marketing aircraft with overhauled engines, don’t make assumption. Not every engine program on the market is designed the same. Call and talk to our team for an OEM solution.

The parts category that contributes most to the cost of buy-in, Delray explains, is life-limited parts (LLPs). These parts, such as the rotating wheels and discs in the engine, typically have a life in the range of 7,000 to 15,000 cycles.

If an LLP is not replaced at the first overhaul, their life is not reset to zero. Rather, it continues to accrue. So, when you enroll in an engine program with LLPs after the overhaul, there may be a buy-in for the cyclical life of these parts consumed up to that point.

LLPs AND MAINTENANCE COSTS

For aircraft with higher hour-to-cycle ratios, many LLPs will likely make it to the end of the economic life of the airframe, so some owners may elect to opt out of this additional program coverage. For example, if the hour-to-cycle ratio is around 2:1, an LLP with a limit of 15,000 cycles won’t expire until about 30,000 hours. The aircraft will probably be out of service by that point.

However, as Delray remarks, an often overlooked point about LLPs is that they can be required to be replaced for other reasons than cyclical limits, such as environmental impact (corrosion, erosion, etc.) as well as wear and tear beyond the limits.

There is no one-size-fits-all solution for aircraft owners and engines,” he adds. “Some programs on the market cover LLPs and some do not. One advantage of our ESP program is that on most engine models it offers customers the flexibility of choosing whether they want LLP coverage or not.
