Some Boeing 787 turbine blades can crack within 1,000 flights: Chinese study
A study by Xia Xiaofeng of Xiamen Airlines found that some Boeing 787 turbine blades, specifically GE's GEnx-1B Phase 2 and 2+ configurations, can develop cracks within 1,000 flights due to thermal fatigue. The issue has led to engine removals and increased maintenance costs. As of August 2025, 15% of the global fleet still uses these blades, with GE revising maintenance criteria based on operational data.
