A runway inspection revealed engine debris on the runway.
The Danish Havarilkommission (HCL) reported a first preliminary engine inspection revealed the front compressor drive turbine had disintegrated and opened an investigation into the serious incident.
On May 12th 2015 Denmark's HCL released their bulletin reporting that the engine failure was contained and concluded:
Based on the findings, the AIB concludes that the fracture in the 3rd stage LPT blade number one was caused by fatigue. Neither defects nor structural abnormalities explained the initiation of the fatigue crack.
The HCL reported: "The visual examination of the engine revealed that all 3rd stage low pressure turbine (LPT) 88 blades were fractured at or near the airfoil root above the flowpath platform. The examination revealed that one of the 3rd stage LPT blades (blade number one) had signs of heat and fatigue in the fractured area. There were no indications or signs of fatigue on the remaining parts of the other 3rd stage LPT disk blades. All 4th stage LPT blades were fractured at the blade airfoil roots. The remaining parts of the 4th stage LPT disk blades did not reveal any evidence of fatigue. There were no observed signs of LPT or exhaust case breaches, no signs of case flanges breaches, and all observations indicated a contained engine."
The HCL analysed: "All the 3rd LPT blades were installed as OH blades during a back shop visit in 2006. The visual examination of the 3rd LPT revealed that one (blade number one) of the 88 3rd LPT blades had signs of fatigue. The SEM confirmed the fatigue area and the microstructure examination clarified that there was no material or structural abnormalities present. ... The indications for 3rd stage LPT blades notch wear could not be observed. The root cause to the fatigue could not be exactly determined. However, a possible scenario, which might have led to fatigue, might be a result of wear in the mechanical blade interlocking feature during normal operation. This might have led to worn 3rd stage LPT blade notches and loss of vibration damping."
