To fly or not to fly: Chinese mechanic reports short-lived GE engine blades in Boeing 787
A Chinese aviation specialist has reported that some high-pressure turbine blades in US-made GE Aerospace engines powering Boeing 787 aircraft have suffered unexpectedly early damage, leaving airlines with a difficult choice: replace the engines or continue flying under strict inspection requirements. The findings raise questions about the reliability of American aerospace products amid growing…
A Chinese aviation expert has discovered that certain GE Aerospace engine blades powering Boeing 787 aircraft are developing cracks prematurely, causing airlines to face a dilemma: either replace the engines or continue flying with strict inspections. The report reveals that cracks can form in some blades after around 1,000 flights, posing a risk of metal fragments breaking off.
Xia Xiaofeng, the author of the study, found that five engine removals were linked to defects in the Phase 2/2+ HPT blades. The 787 aircraft has two engine options, General Electric GEnx-1B and Rolls-Royce Trent 1000, each posing its own set of maintenance challenges. While early blade damage doesn't automatically render an engine unsafe, airlines must closely monitor the situation and replace the engines before the defects exceed acceptable limits, adding to maintenance costs and operational pressures.
The findings come amid concerns over the reliability of American aerospace products, following a series of incidents that have raised questions about quality control and safety in the industry.
