*aerospace · news · 2026-05-04 · Simple Flying*

## Key points

- Boeing offers two engine options on the 787 to drive competition and reduce supplier risk.
- GE's GEnx engine powers about two-thirds of 787s, favored for durability and time-on-wing performance.
- Rolls-Royce's Trent 1000XE triples the time-on-wing over earlier models, addressing past durability issues.
- Airlines rarely switch engine suppliers once chosen, as maintenance and operational ecosystems are complex and costly.
- The dual-engine model stands in contrast to Airbus A350’s single-supplier approach, affecting certification and flexibility.
