Understanding your engine’s true maintenance status begins with one essential question: Where is the engine in its maintenance interval — and what is that interval?

With many next-generation engines now operating under OEM-issued extensions or “on-condition” requirements, determining this accurately requires more than relying on electronic tracking programs. At West Star Aviation, our specialists always dig deeper, starting with the most authoritative source: the engine logbook.

Maintenance Intervals Are Changing — Your Tracking System May Not Reflect It

Many modern (next gen) engines have received interval extensions, while others rely on hourly borescope inspections or OEM trending systems that may permit pushing a scheduled event further out. A quick review of the logbook often reveals opportunities that some electronic systems overlook.

This past year alone, West Star has worked with numerous operators who believed their engines were approaching “a required maintenance event”— only for our team to discover, through detailed logbook research, that additional operating hours remained. As we often hear: “My CAMP doesn’t reflect this.”

The truth is that digital maintenance platforms can struggle to stay fully aligned with the latest OEM service bulletins, interval revisions, and extension criteria. That’s why we always reference the logbook: the definitive record of engine status and service bulletin compliance.

Growing Complexity in Cycle-Limited Parts Management

With ongoing supply chain challenges, the industry is seeing an increased trend toward reinstalling cycle-limited parts rather than replacing them with new components. While this is a practical solution, it introduces added complexity in tracking and forecasting what will be required at the next scheduled event.

West Star Aviation works directly with operators to interpret these changes, ensuring you understand not just the current status of your engine but also the implications for the next maintenance event.
