GE Aerospace Engine Blade Cracks on Boeing 787 Fleet Trigger Multiple Removals as Stock Slips With Industrials

A Chinese aviation specialist has reported that high-pressure turbine blades in GE Aerospace engines powering Boeing 787 Dreamliners can develop cracks within approximately 1,000 flight cycles. The defect, tied to Phase 2 and Phase 2+ HPT blade issues, has led one airline operating 787s to record five engine removals from its fleet as a result of the problem.

The HPT blade cracking concern adds scrutiny to GE Aerospace at a moment when its stock was already under pressure. Shares of GE fell alongside the broader industrials sector on November 2, 2026, compounding a slide that has brought the stock well below its August 2026 highs. The company had previously raised its full-year profit guidance on the strength of engine repair demand and spare-parts revenue, and had delivered more than 50 GEnx engines to Boeing in the third quarter as the planemaker targets a production rate of 10 787s per month.
