The Engine Assurance Program (EAP) was founded to fill a void in the marketplace. EAP offers a high-quality alternative to engine coverage for the older engine platforms. When you maintain the engines using an hourly maintenance program, you maintain the value of the aircraft. This is especially true for out-of-production aircraft. Aircraft are much more likely to be taken out of service and parted out if they do not have an engine program when the engines come due for heavy inspections. ​
