We’re excited that this high-performing engine now has access to EAP’s high-performing support,” says Sean Lynch, EAP managing director. “With EAP, you only need one resource to help with all your engine coverage needs versus dealing with multiple different OEM programs. That saves customers time and effort.” EAP continues to expand the list of engines covered by its hourly maintenance program.
