ST Engineering and LOT Polish Airlines have expanded their long-running partnership with a five-year nacelle MRO agreement that puts predictive maintenance at the centre of lifecycle management for the airline’s 15 Boeing 787 Dreamliners.

While the agreement extends exclusive nacelle support, its defining feature is the introduction of a structured refurbishment programme designed to transition LOT from reactive maintenance practices to a predictive, data-driven operating model.

The programme embeds predictive maintenance methodologies directly into nacelle planning, enabling earlier intervention, more accurate forecasting and improved alignment between technical decisions and operational outcomes.

Using soft time-based scheduling combined with predictive reliability modelling, the approach is intended to anticipate component degradation before it leads to disruption.

By identifying emerging risks earlier in the lifecycle, the programme aims to reduce unscheduled removals, stabilise turnaround performance and improve aircraft availability, while giving the airline tighter control over maintenance costs and asset utilisation.

Henrik Scholtfeldt, head of global nacelle MRO at ST Engineering, said: “This agreement reflects LOT Polish Airlines’ continued trust and confidence in us to keep their Boeing 787 Dreamliner fleet flying safely. By including predictive maintenance in our partnership, we are able to further strengthen our service consistency and support LOT Polish Airlines in reaching higher cost efficiency and operational resilience.”

Wiktor Radon, technical operations managing director at LOT Polish Airlines, said: “This programme is a strategic investment in operational efficiency and long-term value creation for fleet resilience.

“Predictive maintenance provides measurable advantages: fewer unscheduled events, assured turnaround times, and enhanced aircraft availability – outcomes that underpin our financial objectives and reinforce service continuity for our customers.”

ST Engineering’s global nacelle MRO network includes facilities in Stockholm, Baltimore, Melbourne and Xiamen, as well as over 10 additional service centres and asset pools worldwide to provide round-the-clock support and availability to asset pools of exchange units.

Its nacelle MRO programmes have been certified by multiple aviation authorities, and are approved by major aviation OEMs such as Boeing, Airbus, Safran and Collins Aerospace, enabling it to provide OEM-aligned repairs to a global clientele.
