The XE durability step is delivered through a redesigned high pressure turbine (HPT) system that triples time on wing – aligned to the 4–6 year operational window expected in mature widebody fleets.
By increasing cooling airflow and reducing core metal temperatures by 45°C, the XE addresses the constraints that previously impacted availability. For frontline teams, the outcome is simple – more time in service, fewer unplanned events and a lower reactive management burden.
The re-engineering also supports an approximate 50% reduction in maintenance man-hour burden versus earlier standards, reducing on-wing inspection workload and stabilising forward planning.
